- PREVIOUS VID IF YOU MISSED IT:
• Mercury 2 Stroke V6, 6...
There was an amazing response to the first episode in this series that covers the design and development history for the Mercury 2 Stroke V6 Outboard( • Mercury 2 Stroke V6 Hi... ), and the 2nd episode covered the new project boat that came with a 150hp Black Max XR2 in detail. The boat was acquired dirt cheap because it wouldn't start and the seller needed to move, so I jumped on it!

This episode skips ahead a bit on what I've done to the boat, to show you our first day on the lake with it. I'd never driven this boat before, and based on how weird it revved in the driveway, I wasn't sure it'd even get up on plane! Of course we ran into some issues, but I did get one top speed run, very limited, just to set a baseline of what this thing can do!
#MercMonday #MercuryOutboards #mercuryracing
Sweet rig! Congrats! A couple of things to help the motor run a little better; change out the poppet valve, if you've got a working tell tale, but the solid beep goes off its an overheat due to the water pressure being too high in the block, can't give up heat because the water is moving through too fast. Change the wires that run from the switch boxes to the coils, they break down with age and will cause idling issues and misses at high speed. If you strip one of those wires, the copper will show a lot of oxidation. Remove the idle stabilizer / electronic advance module; they can cause issues with the timing are are there because Mercury didn't know what propeller would actually get mated to the motor. Get rid of them and adjust the timing with the prop you're going to run, it'll wake that Xr2 up nicely. The oiler is a known weak point, the nylon gear on the crank doesn't like getting spun above 6000. Either remove the oiler / run premix or keep things below 6000. If there is an intermittent beep, its either the tank sensor or the oiler sensor, pay attention to them both. With a 21p trophy plus, 60 is very much in reach, a 23 will get you to about 65 all jacked up. Enjoy!
Thanks for all the advice! Sarah changed the waterpump yesterday, and I have a poppet valve kit to put in, and a set of thermostats. Great tips on the wiring! How do you adjust timing with the prop? I'll have to look that up. Yeah, about the oiling system, I'd like to keep it if possible, does anyone offer a replacement gear out of a stronger material, like delrin or aluminum? The prop on it right now says 22p, and it's flawless. Not sure if it's a real trophy or a knockoff but it sure looks nice.
Happy to help - I've got a Centurion with the same color scheme. :-) To adjust the timing you'll need a test tank, the spec from the factory manual, and a timing light, the test tank is needed to simulate having the boat in the water at the right level, need to have the right back pressure (the ear muffs won't create that). You'll be able to set the idle and timing in gear; that will get the idle dialed in. The in-gear idle RPM and timing is very much influenced by the prop you run, a tallish prop like that will bog the motor a little as it slips into gear. The stock buzz box that compensates for that eventually burns out with age and can introduce an unstable element to the timing curve. The WOT timing isn't set in gear, but also needs the test tank to get it just right. Its amazing what a difference a little adjustment can make, just need to be careful. On the oiler, its a nylon gear right on the crank, only Mercury makes it and the only way to reach it is to split the block. The reason its nylon is as it ages, the nylon won't tear up the crank and the bearings as it wears. If you're going to keep the oiler, make sure the sensors and the control box are working properly, they will age and stop working. Its a reliable system as long as its maintained and kept within the operating parameters Mercury intended. Happy boating!
@@philiplewis1774 Awesome information, thank you so much! I'm doing the poppet tomorrow night. Or maybe friday. Before the weekend!
new sub just for the fact that you pinned this epic comment. I find that, for me anyways, youtube or even google never has a cookie cutter answer for the weird shit im working on,,, like ever. so through comments, research, and random bits of information, that i may or may not remember, i may find a "method" to remotley get me closer to a solution... I go thru boat chapters as well lol A LOT of knowledge for older boats and stuff in general is withing the older guys (and gals) and is likely to never ever be published or even passed down unless one asks .... which is why i try to help by sharing ACCURATE informations when it comes to technical fixings and operations of vintage'y stuff.... THEN I READ YOUR USERNAME...!!! and being someone whos been ... i mean is currently and always learning how to deal and live with my add....... that was the cherry on top! if ever in GA, hmu... lol as i listen to the vid and type this, i realize your other half is ismilar to mine in the sense that shes the analytical ears, eyes, and observatory geniuis that makes it all possible. harrd to explain but im know you get it. that kind of syncronicity can only be understood only if youve ever experienced it, and can only be forever if its aknowledged.. ok, im off to check out your other vids!
@@ADDvancedp.m.
That beeping is oil level. When my 87 xr150 beeps on and off its oil. Solid beep us over heating. Hope that helps.
I had the XR4 version of this motor on an 18ft VIP ski boat and it was BA! Best sounding outboard around! It would do 72 mph on a 21p Quicksilver Laser II prop. These motors are tempremental.1. Add 1/4-1/2 throttle and push the key in for the fuel enricher to start easier 2. They do not like to idle for long stretches. The carbs load up and it floods out. These were made to run, not troll. 3. Don't trust the water stream to determine if water pump is cooling. I changed water pumps every two years on mine. The impeller is undersized and, for some reason, wears out very quickly. Add a water
pressure gauge to help monitor cooling and predict water pump replacement. 4. Ditch the oil injection, it will eventually fail. I was quoted $700 to replace it and that was in the late 90's. Previous owner converted it to premix because it failed on him and that's how I always ran it and never had a problem. Watching this makes me wish I had it back lol.
I have a 92 mercury 175hp 2.5 on a 19ft SeaRay. Won’t do 60mph with the ski prop on it. This video made me so happy. You two are great. Keep up the great vids! P.S. I hope you heal up good as new,. I’ve had broken ribs and it’s a slow healing process if you don’t take it easy.
Will do! I'm not sure I'll have one this week, it's been raining since Friday afternoon here. Hope it clears up tomorrow; Sarah changed the waterpump and I want to run it and see if it stops overheating.
That sounds extremely high. I had a 1991 Sea Ray 160CB with a 150 XR2 which makes about 10-12 hp less than the 175. Boat was not painted and well dialed in. Best I ever saw on GPS in saltwater was 58 running a HighFive. Not sure how a 175 will ever push a 190 to 60, even if it was running a Laser II.
It was an un expected obsession but I just watched the entire build to this point on the other boats and both about this one. Loving the content. Its hard to find boat content.
I'm liking this guy's boat content as well - you're right, there isn't enough of it for the few of us who are obsessed with them.
Personally, I feel like some of the older and smaller runabouts (1950's through 1980's like this one) are going to start to becoming more 'hip' and popular as time goes on. Especially ones that are small enough to be towed with a passenger car or small pickup truck. Just like the 'cafe racer' craze and what it's done to the motorcycling world.....
I guess it'll be cool to see it gain in popularity if that happens, but deals like this one will definteily dry up too!
I feel like most boat content is new stuff for super rich people, and it's just out of reach for normal working class people. I don't get it. When I was a kid the rivers were full of 16-20' "sporty" go fast boats, ski boats, bajas, hydrostreams, glastrons, etc etc etc. I work in the marine industry and that entire segment is just gone; people buying new boats either get a pontoon or some boring open bow family camry type boat. Or a $150k wakeboard boat, or $250k high perf cat. The "affordable" performance boat is gone.
High temp alarm wired to temp guage (tan wire or tan with light blue tracer) @ dash.
On the engine side the temp sender's located near top of each head facing back near the thermostats.
You need check the pisser, it's the tell tale visual indicator for water circulation.
I'm so happy for you both.
BTW push ign.key in before turning key to activate your electric choke you will hear the audible click @ the powerhead (yellow with red tracer).
Your ign. Kill & neutral safety is (black with yellow tracer)
Your ign. sending is violet & your instrument lts. navy blue
Thanks for the wiring help! The tell tale was consistent, so I'm not sure why it was overheating. Sarah changed the WP yesterday, and I have a new poppet valve kit to throw in.
I love the sound of those v6 mercs..it's music 2 my ears
Mercs sound amazing
This engine does NOT have a “ choke “ as in choke butterflies, it has an enrichener. It’s a solenoid that opens a valve draining fuel from the top carb bowl to the lower cylinders, turn the key to “ on “ then push in the key for 3to 5 seconds ( depends on outside temp and if engine is warmed up ) the engage the started, that should help .
Thanks, I'll give that a shot next time!
Love your boat projects. Keep them coming. Couple things i recomend. Obviously replace the water pump impeller. I would put new thermostats in the heads, the previous owner may not have done that or replaced them with washers to restrict flow. And me personally on an engine that old i would ditch the oil tank and premix the fuel 50:1. You are missing the oil resivor on the top front of the motor. In part two you aske about those three mounting points on the top front, thats what goes there and there should be an oil level sensor that goes into it.
The 150 has vertical reeds as where the 200 has horizontal reeds. That is one of the main differences.
You should try your coned lower unit on this boat. Raise the motor to where the nose cone is about a 1/4 inch below the pad, that would be a good starting point. Make sure you have a water pressure gauge and that its working. But at a 1/4 inch below you should be fine. And if you run the coned lower unit see if you can borrow a 24 or 26 pitch chopper prop, or some other over the hub surface piercing prop that will help carry the bow. You may be okay to run the prop you have but dont run it any higher than the 1/4 below the pad.
Looking forward to the next video.
Great tips, thank you! Will hopefully have an update in a few days. Cheers!
I got my 78' sleek craft rebel... Big block chevy and a panther pump for $500.... It sat for over 20 yrs.. I just wet sanded and buffed it, started the motor and put new carpet and seats and have been running the hell outta it for 3 yrs now... So nice one...
Join the Sleekcraft group on FB! Post pics!
I like your videos. I purchased a 135 black max. It blew up 1/4 mile from ramp. Sometimes you can't go back in time and make things work. I am glad that you like these motors. Mine going to the scap heap.
Oh no! Were you running oil injection?
Wow, what a deal! The motor alone is worth several times what you paid total for this!
It's hard to beat the sound of a Merc 'Tower of Power', brings grins every time.
Keep up the good work - I stumbled on this channel a bit ago, and the content is above and beyond other channels with way more subscribers from what I've seen so far!
Scope the previous episode if you haven’t seen it. Goes into detail about the boat and why it was cheap.
This isn’t the tower of power; that’s an inline 6. Still a super cool engine, but this is the narrow deg v6 2 stroke that’s still raced to this day on modern tunnel hulls.
Cheers buddy, appreciate the kind words! 🤙
@@ADDvanced - now I see - although you still lucked out. 'Have to get rid of it price' for a boat like that most times seems to go from the 'meh' price of $5000 to the 'I'll now somewhat seriously think about it' price of $2500. There was no decision to be made in this case!
You are correct, that was a stupid comment, which I've apparently grown used to applying to every older, larger Mercury. Thank you for the correction 🤣
Not stupid man, no worries. You wanna see stupid watch me burn my thumb print off on the battery terminal again. Suckkssss.
That’s not a tower of power.
beeping is related to the oil system only. It is normally that the oil is not completely to the top in the little reservoir on the engine. With the engine idling, loosen the cap and let it run till oil just starts to come out. Other options are the Oil warning module, not likely as it was not like that when you first started. Other option is the drive shaft in the oil pump is not turning. To make sure it is getting oil, add some oil to the fuel till you sort out the issue
I tried that, but the reservoir was full. Gasket looked okay too. Temperature was definitely going up tho... I think it was overheating.
@@ADDvanced Maybe listen friend. It is not the heat alarm it is oil. That sensor in the small tank fails quite often. Disconnect the wiring, it is only two wires and see if it still goes off. If not, there is your issue but man... OCD should not stop you from thinking and researching good advice :-)
I’m loving the videos! I can’t seem to find the link to the video about polishing the gel coat.
I didn't finish it in time, it's going live tomorrow! Cheers!
If you push the ignition key in while starting that activates the choke to help get it started on cold starts. Also use trim up when plaining out to help bring the bow down to compensate for pourposing. But make sure trim is all the way down when taking off for quick hole shots. Make sure your engine height to the hull of your boat is set by using your manual jack plate for optimum performance. Delete the oiler and premix never trust the automatic oiler on any two stroke ever.
Yea, it dribbles fuel into the car throats on I think the lower two carbs? I forget, it uses fuel from the bowl of the top one I think, and dribbles it into the ones below
Yes. On my 225 Black Max I would pump the ball, with throttle in neutral choke and crank until it popped. Add a bit of throttle and crank with no choke. For me this never failed. Wet it. Then give it air.
it will actually start better if you hold the key in choke position for 10-15 seconds then crank to start. you’d be surprised. that’s also the way mercury wants you too.
Honestly it's always so warm when I'm boating that I've never really used choke on my sterndrive/carb'd motor. I just left it disconnected.
@@ADDvanced carb outboards are a different beast. 2 strokes in general are, your gonna wanna use that choke, and the right way to have quick starts. she’ll purr
had a 19 foot stearling with a 200 black max growing up your boat has the same shape and listening to it start was very nostalgic. good luck dude! beeping is usually heat or water pressure IMO
Same here! My dad had a 200 Black Maxx on his V191 Checkmate when I was a kid and the sound of that engine taking off in the video brought me right back. Amazing the power of memory. My father passed away recently and just found out I am inheriting his old boat. I plan to rehab the boat and motor and bring it back up to Dad's standards.
Dustin, start a youtube series about it! Would love to see more of these being brought back to life!
SAweet brother!! Your hat is on point! I've driven a 16' Tahiti ski boat with a 150 hp 2 stroke Suzuki on it with a jackplate to the tune of 60+ mph and that was indeed a handful! I know the warning alarm for my 2 stroke Johnson is under the dash
I think I can hit 60 with it as it sits, once I solve that overheating issue. Then it's time to plug some of the higher water pickups and start jacking up the engine a bit more.
I had a XR2 on my Stratos Bass boat, sweet sounding engine! Seeing this video brought back those memories. Nice job on the boat!
Thanks! How fast did you get?
My 83 20ft Avenger had a steady horn under the dash for overheating. 225 Black max so no oil warning circuit. My yearly service I would always dip the sender in some boiled water to make sure it worked. Water pressure gauge on the dash to show the condition of the impeller. Running and idle. I learned the hard way. Don't go 2 years on an impeller. Don't worry about speed right now. Speed is over rated. What's fun is getting the boat 'loose'. Trim out until the boat starts to misbehave then bump down a bit. In my case I would then start jacking until water pressure bounced. No steering of course so just along for the ride at that point. This is a great boat to play around with before you dive into that SST. That's going to be a wild ride
Yeah, not too worried about speed, need to solve the overheating issue. Sarah changed the waterpump yesterday, one of the gaskets did not look great, and was missing a chunk. Going to do the poppet valve soon too, and test it again on the water to see what happens. Then next steps are block some of the upper water pickup holes, and start jacking up the outboard a bit at a time. Maybe cut that skeg into a straight fin again too.
I would definitely get the rear wrap around bench seat for it, and some nice swivel bucket seats for front. Just re-carpet the whole boat, and get new rubber stripping for the rub rail on top cap. Next, I would get a 3-blade 26p Fury or Tempest racing prop. Keep in mind, if you do spend the money on a prop, have a shop balance that prop, and polish it out. That will improve things dramatically. Bilge pump needs to be installed. Yeah, raise that motor up.
Very good videos! I have a similar boat with a Mercury 1400, I want to ask you what propeller do you recommend to have speed and I also want to ask you at what level it is ideal that the propeller is with respect to the back of the boat? higher, lower? aligned with the floor of the boat? Greetings we follow you
I have the exact same motor, only it's an 84, on my 82 BAHA S&S. These motors are very temperamental at a cold start. Mine has an electric choke that engages if you push the Key in. Only way it usually starts. Once she gets warmed up it runs great. Oil injection was already removed when I got it.
Thanks for the tips! Getting better at starting it now.
Regarding water in your transom pan. I had two 1" ID drain fittings on my 20 footer. I learned not to chop the throttle. Just leave 1500 rpm in when coming off of plane.
Used to that with the sleekcraft, since the engine is exposed. Swamped it pretty good once. Sucked.
It’s the gift that keeps giving
Sweet boat! Those V6 Outboards sound so good. If I had it, I’d start with rebuilding the carbs. Either service the oil injection to make sure it’s working properly or delete it and run premix fuel. That boat with a good tune up and the right prop, turning about 6500 rpm at full throttle and trimmed up after plane should do 65 to 70 mph easy. Also, I think some of those have thermostats and yours may be sticking and elevating the temp. Something to check into. Super cool!
That's the plan! Sarah changed teh waterpump a few days ago, video incoming, but then going to do the poppet valve and thermostats to see if it stays cool. Once that's solved, it's time to start dialing it in and raising it until it's barely drivable :D
Yeah I have a Black max Oil injected 135 and we Deleted The oil injection Because if it goes out it will blow up your motor
I’m really enjoying merc mondays! 😎🤙🏼
Cheers buddy! Wish you were closer!
Idle stabilizer is also a timing advancer 5 degrees past timing set to give it better hole shot and top end it needs to stay so it jumps from 20 degrees to 25 and back to 20
The XR2 made 150hp(+/- 10%) at it's rated Rpm. but it had a different Torque Curve when compared to the regular 150, the Midrange was beefier, but it also burned more Fuel. The main difference was the Port Timing, and the Exhaust Tuning.
Late to the party and it’s probably old news by now but didn’t see it happening in the video. Once the bow breaks over start trimming up. Less wetted surface=more efficient use of horsepower. Bow lift is your friend (to a certain extent) on a v hull. There will be a sweet spot where the steering gets soft and easy. Look for a rooster tail but if it’s higher than the cowl you’re wasting horsepower. A water pressure gauge is a must. You can tune the jackplate and trim to see what speeds the boat is actually capable of.
Make sure you do the entire water pump.also look up the water tube with pen light for holes.
Loved the Letterkenny reference gotta get that W boys!
Wheel snipe celly!
On my old suzuki constant beeping is overheat, that fast pulsed beeping is oil low/no oil going through the oil line. The alatm is in the remote, not sure about Mercs though. Gas pedal could be a good choice for that boat.
I think this one was overheating for realsies. Oops.
@@ADDvanced Might be sensible to get a borescope and check the cylinder bores to make sure they didn't get scuffed up by a bad overheat at some point. I've almost seized my little 3.3 Merc before due to the water pump impeller being stuffed, first I knew of it was the engine bogging down because the piston expanded so much that it was binding in the bore. Thankfully there wasn't any obvious damage to the cylinder afterwards.
Need to bump the idle up a bit so it doesn't stall. It's the sensor in the little tank under the cowl causing the beeping.
Just needed to warm up, then it shifted fine. All my boats are sort of like that. Little tank was full/good/sensor moves, I think it's actually overheating. Going to change the WP and poppet valve.
Love the thumbnail wow Sarah 👌
YEW
check thermostats at top of block on both sides close to spark plug follow water hoses to top part of engine. my XR4 stuck and i burnt a piston so i put a 175 powerhead on mine ,i went from a 2.4 litre to a 2.5 litre and boat improved tremendasally mine is on a 18ft ranger bass boat .....
Both thermostats are new, also ran without them in one of these videos
Hello , boat looking awesome ! I have a question I have a 1986 mercury 150hp 2stroke , when ever I put it in full throttle the rpm won’t go pass 1000rpm and it was bogged and almost die . Any idea ? I took the card and clean it .
Gotta be fuel pump, fuel filter, or clogged carbs. Or possibly a fuel line failing internally and inhibiting flow!
@@ADDvanced ok thanks !!!
Nice outboard,I've got a 99 2 stroke 135 and that thing rips....pushes my old 20' proline bay boat at 46 wot with 2 guys and gear.
What a blast seeing your $500 boat run as well as it did!! That bargain's gotta be as much of a buzz as going 60 mph in it! it's a beautiful boat as well. Save the floor replacement and the transom upgrade for later, you've got the the SST to finish!
Glad to see that Sarah is recovering nicely. Sorry to hear about her broken rib. She's a sport!
My dad took a similar spill on gravel. He was a dedicated road bike enthusiast. After that, my stepmom wanted him to give it up. Wasn't gonna happen! We spent many hours cycling together as I was growing up. I have his bike now and will never sell it!!
Keep the videos coming!!
Yeah, thing is super fun! I love how it pops out of the water so quickly, my heavy cast iron stern drive won't do that in the red sleek at all; it will cook up top but if you floor it in the water it just won't hook up. I'm definitely not going to tear into this anytime soon. I am wanting to build seats for it pretty bad, but I think I can do that over winter.
What kind of bike is it? I ride an 80s peugeot, steel. Love it, I've put thousands of miles on it and have maybe $3-400 in it, total.
@@ADDvanced It's a Fuji from the mid '70's. All Chrome moly double butted tubing and Campagnolo components. It also has sew up tires, that as a kid, I always wondered why Dad bothered with the trouble compared to the more conventional beaded tires. He found out how those super thin tires handle in gravel when he encountered a road that was resurfaced with tar and chip (don't know if they do that in Wisconsin). He ended up in a ditch, and luckily a county sheriff saw him and took him to a hospital. He hurt his back pretty good but nothing permanent, fortunately. I wasn't with him on that outing. His bike came out of it relatively unscathed. We resumed riding together a few years before he passed.
My hobby boat (I only have one...so far 😆) Is a '98 Sea Ray boring bow rider family boat that I picked up for $2500 for boat and trailer, The previous owner didn't winterize it properly and the 5.0 L block cracked so I replaced it with a stroked 350 (383) That I built over the winter. Did a bunch of cleanup and replaced the skanky carpet too. Been getting it out a fair amount this summer and have been trying to find the right prop for it. Had it up to 50 mph with a 23P prop and just picked up a SS Ballistic 26P to try. With the 23p I kept hitting the rev limiter so I know the boat's got more in it.
Now that I've been bit by the boat bug I'm looking for a 20 ft maximum Formula, Donzi or Scarab 1 to make my next project. Know where there's any languishing and unloved?
Nice chat. Keep boating!.....And biking!!
I never got water in the transom well when I slowed down to pick up a skier. I wonder if the transom jack on your boat might be causing your problem. You did a good job polishing up the gel coat. Your boat rode very well and seemed to track straight, that and the quality of the gel coat, show what a high quality boat Cee Bee's Avenger was and can be if taken care of.
I'll get the gelcoat polishing video up as soon as I can. I think it took 2.5 hours. Turned out amazing tho! I still think that with equal power, the SST is going to walk right away from this thing.
@@ADDvanced oh yeah without a doubt I concur LOL
If the oil mixture is not correct it may run rich or lean and could also make it run hot.....?
Yeah, maybe? I'm not really sure.... the oil injection reservoir on the front of the engine was full, so I am assuming it is working based on how smokey the exhaust is.
the oil tank under the cowl has a sensor in the cap. if that tank isn't 100% full the beeping will continue just fill the tank under the cowl and the beeper is located in the control bow itself. look by the key and you will see the speaker for the beeper
I checked that and it was full. I edited out that part of hte video since it was boring, but I checked a few times. Hmmm
Yeah hit the lower unit of the motor and the cowling with that buffer and polish and sealer it'll shine up nice too it's almost looking flat black in the video love you guys
Pre mix it and delete oil injection and oil alarm module, you will still have overheat alarm which is constant… that’s a hell of a boat you guys got for the price. I’d throw some good reed valves in and go through carbs , put a new impeller on it too . These motors are super easy to work on .
well, might want to watch the rest of this series. We just pulled the floor on it and found a disaster, lmao.

Dude, I love this boat. So cool.
Trade for space tractor
@@ADDvanced Oh, you drive a hard bargain, mister ...
I have a 150 also a 35 year old bass boat ,,, great fun ,,
I have an old 18' Miller similar hull design with a 1989 Merc Black Max 220 Laser (wearing 150 decals just for the coast guard rating) with a speed master lower unit (no reverse and no threw prop exhaust). Fast & loud toy.
Nothing like my 300 HP Black Max on an 18' Brindella pickle fork. Stupid fast & scary.
Sounds awesome. What kind of speeds are you getting with the miller hull? Pickles are nuts.
@@ADDvanced It's set up for endurance ski, it will run 85 + with my current SS cleaver props.
Talk about the deal of a lifetime!!! Even if you have to tear into that engine to remedy the overheating issue, do some maintenance, and throw a couple mods at it, that has to be the best $500 anyone could pretty much ever spend!!! Its too good to part out or anything like that either. Needs some decent Autometer, VDO, Defi, etc gauges so you can have a little peace of mind. I'm not big on outboards, but in the 2-stroke dept. I build hot saws/ work saws for customers and myself, I'm sure the usual tweaks apply, and if it were me for fun, I'd pick up a spare to do some mild port/ blend work on. I'm guessing you can mod your carbs, advance the timing, etc. Imagine some sick ass velocity stacks! Theres probably loads of these things just sitting around since they are older tech, and I'm sure less folks (except guys like us,) want the 'responsibility' of operating/ maintaining a 2-stroke in general. The great thing like you said, is the 'mixing/ matching' of the best parts, which is def the way to go for the best 'bang-for-buck.' These engines have quite a pedigree, and us 2-stroke guys can certainly appreciate them! 👍👍😎
Check the float sensor in the oil tank on top of motor. And disconnect the oil pump and oil pump sensor. Mix your oil in the gas. Change the water pump. max rpm range is 5800-6000.
Going to keep the oiling system, for now.
@@ADDvanced His suggestion was the most valid thing you could do to extend the life of that engine friend. A bunch of mercs had a planned failure neopreme gear on the crank to run a metal gear to the oil pump. It fails always and kills the engine. Mixing gas and oil is simple. 16 oz to 5 gal fuel. Never die engine after that as long as you maintain it right. That is a no oil or low oil alarm going off. Is there more than a half gallon of oil in the remote tank? Is there a mini tank on the engine above the carbs? It has to be topped off always or an alarm comes.
I have been an outboard mechanic and shop owner for just over 50 years now. Just fyi. Mixing gas and oil is simple and you will never have an oil issue ever again. Just sayin....;
Great Job on repairing the Boat and Motor. With it getting hot would it be the Impeller or rubber hoses could be Plug? How the sheds doing
Nice buy. That motor sounds killer. Great deal
Thanks bro! Still overheating but determined to solve it in a few weeks
Always wear life vests. I had a 89 black max 150 on my glasstream 180 elite and loved it. Have fun but be safe!
The beeping is most likely low oil in upper oil reservoir
Checked it, it was fine. I think it's overheating. Sarah changed WP and I am going to do the poppet asap.
2-stroke POWER
Love the 😁
Whoa! There's no such a thing as "Didn't need another boat." That's crazy talk.
place a level on the back pad of the boat and level it using the jack at the front of the trailer. after that is level run the level from the back portion of the boat toward the motor. it should be above the top water intake on the motor if not adjust he jack plate down.
I am failing to see what leveling the trailer does here; a straight edge off the pad vs the gearcase should be all you need. Why would I level the trailer as well? Thanks!
your not leveling the trailer, you are using the trailer to level the back end of the boat so you can now level from that point the the water intakes on the lower unit of the motor to make sure you are getting adequate water flow
@@tomsales263 But why do you need to level the pad? A straight edge against the pad should be all you need.
@@ADDvanced just to make sure you are getting a good water flow to the water pickup on the motor
when I check a transom on the trailer tilt engine up grab lower unit and lift it by hand up n down while watching transom
That's just EPIC!! Five hundred dollars!! Amazing!
500!? No fair!
2+2 is like a turbo when the second pair of cylinders kick in at 1800. Love our old 100.
The beeping could be the bottom end low oil warning.
Solid beeeeeeeee is “ hot “ the beeping is telling you that the oil in the engine mounted oil tank is low or the float sensor is bad .
I was thinking the same thing! It's out of oil in the sending tank!
I checked, it was still full. Meanwhile the temp gauge was climbing and climbing. I think it was hot.
That is an oil alarm. If the top tank is full your plastic gear that drives the pump is worn/stripped. It has a rotation sensor that detects when pump is not rotatating hence the temp climbing. Premix fuel.
The beeping could also be a faulty sensor as well for overheating
Good idea, tho it was going up and up and up. Sarah changed the waterpump already, and I will replace the poppet. Then another test rip to see if it solved the problem, if not, sensors I guess?
@@ADDvanced yes, it’s definitely a possibility, but the temp could also be showing hot from a faulty sensor feeding info to the gauge. However, good call on the water pump. It could also be a blocked passage somewhere too, but I kind of doubt that or it would start almost instantly when it gets up to temp.
@@ADDvanced check your thermostat too, might be stuck closed or badly corroded.
I thought they only made the XR2 for one year 1985 155 hp I thought XR4 came out in 86 ???? witch had the high speed gearcase from an inline six and different gear ratio
I think there were 2 different XR2s. One was a hardcore race motor sold primarily in Europe. The other was this one based on a black max that’s slightly hotter.
I'm a merc dealer and as far as I knew they made a XR2 1985,an XR4 1987 and a XR6 1990/ 1991 USA. I dont know about European@@ADDvanced
I’d wanna see you put hydraulic steering on that 150. Above 115 hp it should have either dual cable steering or hydra iac. Also that beeping is part of the oil alarm system. Overheat will be constant tone. Look to see if either the tank on engine is low or if the oil pump drive is bad,( it’s a plastic gear driving the oil pump). Hope you guys enjoy that boat!
I'm not sure that's correct. I checked the oil reservoir under the cowl several times, and it was full every time, meanwhile the temp was climbing towards the upper end of the gauge. I think there is some confusion between beeping (beep beep beep beep) and a single tone (beeeeeeeeeeeeeeeeep), both of which could be "continuous" or "intermittent".
Check the heat sensors
Another rabbit hole to research, thanks!
Sarah video !
It is a darn good looking boat!
Really happy with how it's turning out. Can't wait to do carpet and seats.
Beautiful views, the boat is cool to :)
Cheers!
That is totaly normal for the big 2 strokes. they don't like to be cold. gotta warm them up and then they run perfect
I have the same engine on my 18 foot tide craft Wildfire bass boat and it does 72 mph with 2 ppl in the boat. and those engines are bulletproof
You have a 150 XR2 and hit 72?! dang!!! What prop?
@@ADDvanced i beleive it's a 19 pitch but it has 1 degree of cup added to it. Up here in Canada where i am there is a place called the prop shoppe.( on lake of the woods Kenora Ontario Canada) I took my whole boat to him and he made me a custom prop based on the boat I have. it runs 5300 rpm wot trimmed all the way up
Don't know if it's been said yet but hopefully it's going to power
What is going to power?
Super nice...Mercury xr-2 = Mercurys answer too bass tournaments 150 h.p. regulations. hot little 150! 168 h.p. at the prop!!
For real? Dang that's more than I was told.
Over heat would be a solid beep
$500 with that engine idling and revving sound, that's a win..minus the beeping alarm
Watch the previous vid, seller couldn't get it started and slashed the price. I figured it was at least $500 worth of parts if the powerhead was burnt up.
Awsome! Now got that SST done!!!!!
Running out of summer! We will see. 911 is next!
first time watching a vid, I gotta say, I LOVE videos with the two of you working together on a project :) Sarah is the Ultimate Babe! Bad As* AND Brains! ;) She gets in there and turns wrenches and gets dirty with you! Smooooookin!!!!
Did you know that temp gauge sender only reading metal temp not water temp
It sure skyrockets when I get on plane, and there is NO WATER COMING DOWN THE EXHAUST. There is a blockage somewhere and I haven't figured out how yet.
12:07💀💀💀💀💀💀💀💀
Nice video and nice boat !! What was the problem with the engine?
Thanks buddy! Sarah pulled the lower unit and found a gasket on the waterpump that was missing a section. Next video will include her changing the waterpump and another test run.
Does Sarah know how to fix the engine? : D
Probably there was little water pressure and the buzzer sounded.
Ok I wait for the next video! Greetings from Italy
I know everyone's saying choke but these motors in particular have an enricher. It allows gas from the top carb bowls to flow into the bottom carbs. I have an 83 150 black max. To start hold it for 10 seconds then tumble.
Thanks for the tip! I'll try that next itme for sure
Bud I have the regular carburated steel sleeve 150 Black max 1987. It pushes my 19' CC wich is a lot heavier than that boat 50 mph. In that boat your looking at 60 to 70 mph.
ALWAYS service the cooling system on an unknown motor! at the very least make sure its not overheating at idle by taking temp at the TOP of each head. 125-152 degrees no more no less. thats nuts great way to stick pistons wow.
Looks and sounds great! But I feel like I wouldn't go on a maiden voyage in any old rig, regardless of how good it looked, without maybe having my life jacket at least draped over one of my shoulders! 😂
Swimming is fun, too
sometimes putting it in neutral and giving it some RPMs can push more water through a weak pump and cool it down. Shutting it off can take longer to cool it down. This obvsiouly depends on the situation. That being said, your fuel guage is at Zero.
Fuel gauge no workie :P
Are you using the trim at all?
Of course. That’s why it was porpoising sometimes; gauge doesn’t work so just listening to the rpm’s.
Nice, did good job cleaning, waxing the boat! Couple questions: what was that peeping, no oil??, and how long is the boat??/ For $500, that is a Sin ;o))
It was overheating. I think the boat is 18', I was told it was 16 but I have not measured it yet.
Ah I can see your drain plug now. Center the lower subfloor plug right at that yellow/orange border. I went back to look at pictures and that's where mine was. Weird deal man.
I'm not even sure how to check if there is water down there. Ideally you'd want the two brass drain plugs to go into each side, then use a drain plug installation clamp to compress them together. Without access to that lower area from the inside IDK how you're supposed to install one.
@@ADDvanced Yes from outside only. Once my hole was drilled. I cut the sleeve roughly an 1/8" longer. Used resin with a bit of cabisol to thicken. Middle finger to coat the bore and shmag a bunch on the inside around the hole. Tapped in the sleeve and fingered in more resin on the inside. In my case I could hear water when lifting the trailer tongue up and down. It was enough to hear sloshing. Ear to the floor? Screw driver trick or stethoscope? If no water don't do it. It is a hand laid boat. Not sure how I got water in mine. It was well sheltered.

Get a nice chopper raise it. Another 3or 4 inches you can probably fly it up to 70. Also some stainless reed
Most people want over $500 for choppers. Gotta find a deal....
@@ADDvanced Gotta pay the price for everything that is worth it.
@@ADDvanced speed ain’t cheap lol but hey 500 for the intial setup your way ahead
I would love to find a $500 deal like that. Very cool!
I look at boats all the time. This basically never happens. And if it does happen, somebody else is usually there first. i saw a flawless daytona eliminator go for $3500, pristine gelcoat and hull interior, no seats, no drivetrain. Total steal and it looked AMAZING
2 stroke is awesome.
BRAP
That top speed though! Totally worth it
yeah and I didn't get on it long because it was overheating. Once I fix that I'm hoping to see 60.
I. Bought a 1980 thompson 2 yrs ago 500.00 remodeled it completely
Be sure to check out the previous vid, shows the initial inspection of this thing. It has some issues...
If possible and you can afford run a test run with the sharrow prop propeller
That prop is slow. It’s for efficiency and torque. Not speed.
150 xr2 engines have 175hp at least here in holland.
Maybe it's thermostat that is not opening all the way. Take a look and see.
Going to replace both of them
You should trim it up more to get more speed, you should get a rooster tail outta that 150
Cool ole boat
Agree! I like this better than most new boats to be honest
Didn't notice any water coming out. But the water pump is gone It's not spitting water out
th-cam.com/video/4t8DMHdi5qU/w-d-xo.html
Get to the chopper! it will be a lot quicker than the over-bladed prop on now (more holeshot, but more drag & less speed)
Nice! It looks like it will be the best boat ever! Cheap!...er
SST will destroy this thing, but still love it!
