When to give up on an outboard motor
ฝัง

- This video is about when to give up on an old outboard and just replace it. Eventually an outboard will just be too far gone and fixing it is no longer a good option. In this step of the Green Machine restoration project I remove the old motor from the hull in order to get ready for the new one arriving. Removing an outboard from a boat involves removing the wiring loom, the control cables, the steering cable and the four bolts that secure it to the transom. I then use a standard engine crane to lift it off the back of the boat and put it onto a wooden outboard stand.

great vids mate, your vids have vastly improved my knowledge on boat engines. Ive even been able to work on my outboard confidently. Cheers
Thanks Luke, glad the videos helped you. :)
Gently tap on the ends...
BAM BAM BAM BAM
LOL
Yeah-- I loved those 'gentle taps' too... I fell out of my chair...
When I did a rebuild, I had a feeling it was 1 piston bearing failure. Took it all apart and checked on part availability before I started. Ended up being much cheaper to rebuild the entire outboard than buy a used one or new one. Luckily no damage that couldnt be mended, 2/4 pistons needed to be replaced but other than that good to go. All new seals, gaskets, and some serious cleaning.
I've had great success with Evinrude motors all second or third hand, I've never spent more than a $1000 on one. I use them for a season tune them up and get rid of them to finance the next project. My favorite are 80's- 90's 40-45 hp Evinrude/Johnson our boating season is short so they tend to last longer than most places. I had a 69 Evinrude 18hp that I bought for $120 and turned it into $500 with a half hour of wrenching. Looking forward to your restoration vids of the boat.
There is no doubt you can get great second hand motors, that's for sure. It is a good point about having a short boating season. All the second hand motors around here have been used 365 days a year in salt water, so by the time they are 20 years old they've done a lot of work.
“Gently tap on the end” as he reaches back for three full swings.. hahahaha.. looks like you couldn’t wait to beat the hell out of that thing💪🤣
It deserved it. ;)
On the ocean. When to give up is a bit different than if you’re on a pond. In my opinion. I can live with the occasional hiccup with my freshwater boat. I have an oar and a trolling motor that can get me to the shore line. On my center console. It stays on the saltwater all summer. If I start having issues while offshore. That’s a totally different animal.
Agree completely. Running around the river here with a boat that might conk out is no real risk at all, there is always someone around to give you a tow.
B.O.A.T= Bring Out Another Thousand$.
You have no idea how many people I’ve had that wanted to repair a “dodgy” outboard. When they insist, and get handed a repair bill for more than what the outboard is worth, they get upset. I’m certain you see more of it dealing with salties than I do dealing with freshies, but I digress. Greetings from Ohio, USA. One day I’d love to come to your country to pay a visit.
Yeah, old outboards are definitely DIY only if you hope to keep them running. The bill will exceed the value of the outboard very fast if you pay a pro to work on it.
I just had a customer ask after a full rebuild on a 1979 Merc V200 what his motor is worth....about half of what your bill is going to be!
Steve, I’ve got one in my shop presently (1978 Merc 25) that’s had the snot beat out of it, has electrical issues, and a gearcase leak. When I asked what his budget was, he replied “between $800-$1000.” 😳 It’s your money pal!
@@ripperace I think he’s over budget with the needed repairs! Craigslist?
As odd as it may seem, I instantly have more respect for anyone that actually owns a cherry picker.. cheers!
Those of us in the auto repair industry will say to "jack the radiator cap up, and roll a new car under it" when a car has all the good wrung out of it.
As always, very informative. Thanks for posting another of many excellent videos.
I like that saying. :)
Hey Dangar, Your videos are so perfect i think I've seen almost every one. I watch them just to learn not that i need to change my dog clutch. lol But this video hits home. I recently gave up on a 50 HP seahorse Johnson that ran great and Have kicked way to much money into its replacement Anyways. What happened was the Gearcase wouldn't split from the midsection because of either driveshaft corrosion or twisted splines. I tried wedges and even cold steel chisiels. I could only get 1/16 separation around the whole thing. I took to a local mechanic he's said i was *&$%ed. In your opinion do you think i gave up to early? I should say I gave up when i saw gas and oil burp, then run down the from of the cowling by the driveshaft, which i thought was the crankseal. THANKS FOR THE AWESOME VIDEOS
Hi mate, glad you've been enjoying the vids. It's really hard to say exactly when to give up on an outboard, but when you can't get it apart to work on it it sure is hard to move forward. Sometimes buying a similar model and using the old one for parts can be a good way to go.
When you cant get jets out or any screws that are stuck, strip the part to metal then take a fire torch and heat it up then throw it into cold water quick change in temperature changes the size of screws and rest of materials that makes it easier to move off the screw
Yes, you can't beat heat (and particularly heat changes) to free up stuck parts.
Watched few of your videos and I must say that I like that you are thorough and reasonable about your marine repair.
I had that happen when a carter pin some how got in between the teeth and broke the starter mount but tig weld it right up no problems
Another superb video by mr Dangmar as usual..Thanks 😊👍
Thanks mate, glad you enjoyed. :)
The old yammy and the green machine were married and didn’t want a divorce...:)
I would of named that engine on the green machine Frankenstein Stu.It certainly has had some butchering.It must be nice to have Paul lend a hand helping out with a bit of camera work.Good work guys and keep em coming.
LOL, I like the FrankenStu. :) It is great having Paul in the shop when we film, certainly makes things easier and more fun.
That outboard was holding on for dear life even after you pulled the bolts. It just didn't want to retire!
A testament to the strength of Sikaflex.
*This video title is my life’s question*
I've been wanting to buy me a boat and totally refurbishe it. but was concerned about the motor work part of it. I must say you've made that no longer a concern. thanks for all the great videos you've posted and look forward to your future videos. I WILL BE BUYING MY DANGAR T-shirt
Thanks Quentin, sounds like you've got a great project ahead of you and I really hope the vids can help you with it. Good luck and safe boating. Send me a photo!
Great channel! Honesty and clarity! Brilliant though, after watching for an hour and a half a dude walks by with a stubby..... Great channel! 😁
+Ronan o hEidhin Thanks Ronan, glad to hear you've been enjoying the vids. :)
You're welcome: keep up the good work.
Dang, that's a tear-jerker! I hope I don't ever have to give up on my 1986 Johnson Looper. It's power/weight can't be beat, but parts are increasingly becoming an issue. :-(
Feel the same way about my '81 Johnson. Many years of dependable service. Realistically, many parts are weakened by age and becoming worn, she can't last forever.
I have a 2006 - 50 Honda and I been trying to figure out i switch my trim motor twice now o have a click on the motor and on the gear box what else can I try to do next besides getting a whole new one I have switch them twice and I get the same out of both of them any tips
"Just give them a slight tap on the end"...... BAM! BAM!!! BAM!!!!!!! :D I lolled to much from that....
Great video's, your voice is all over the place though. Get a lav mic and a small zoom recorder you can wear. Sync audio in post, and your voice will sound much better and consistent. Keep up the good work!
Thanks mate. I think the audio is much better in the newer videos. I went with a shotgun mic on the camera in the end although I did use a wireless lav mic for a while.
Sennheiser MKE40 is a great choice ;)
Can't wait to see the new install will it be yamaha a mercury or a honda.......
I'm looking forward to the new motor too, and to be honest, I really have no idea what it will be yet! :)
"Stick with the devil you know" Truer words have never been said considering boat motors lol
Its probably not a misalignment.
Its more than likely simple fatigue.
All that aluminum dust looks very familiar to me. I have been running a 1989 40hp Johnson for 3 years. This motor was given to me so I have very little money in it and no particular attachment to it. Something under the flywheel is grinding away, that is the source of the dust on my motor. It also has low compression in on of the cylinders and a leaky lower unit. it is time to give up the ghost... I happened across a 2006 40hp Etec for a good price. The best thing about this new motor is that it is basically brand new. It only has 2 hours of run time! The previous owner thought is was too much motor for his boat so he swapped it and the motor has been in the shop for years. It was properly winterized before it was stored. I picked it up for 2500. I am keeping my fingers crossed that it will be ready to pick up tomorrow!
+mike underbrink Sounds like you've made a very wise choice. I hope the new motor gives you many years of happy boating. :)
Good point..
I used to make aluminum support brace for weak starter mounts bolting to other spots. Also low speed screws can be heated to back out..I grew up on salt water motors in NY...needed torch for everything..Not good for a daily commuter motor though...cheers.
Sounds like a good idea. You can't have enough reinforcing with the torque these motors generate.
Hi sir first of all I want to thank you for the video
My question is there's a very Ald 17' ranger 115hp jonhson, for sale for $2,500 start ok and sound normal he sad the compression on 2 top was 125 and the 2 bottom 120 but I saw oil on bottom by the spark plugs he sad that that's normal on that engine due to the carburator, it's that right?
Yes, it is very common to see in oil in the lower cowling of a two stroke motor.
one thing also is the parts value if u got the time can be worth alot towards a different out board
I bought an old evinrude 15 hp 4 stroke of a kid who gave up on it. everyone told me these were bad engines, they said even the dealers gave up on them. HA!! it just needed a new powerpack. I rebuilt the carb, did the waterpump and gearcase seals and it runs like a champ, it's quieter than my 2021 suzuki 20 hp.
anyone know how your supposed to transport these things? the bumpers are on the back, not the sides?
Take those corroded carbs and soak them in a pail of oil for a couple weeks before you try moving any screws.
My Yam f40 needs a fuel injection HP pump. The cost is 450... I am thinking twice... I heard a bad clicking sound too upon my last run up
Hey enjoy your shows do you answer outboard trouble shooting question
my favourite channel on the hole of TH-cam 😀 love it
Wow, high praise indeed! I'm glad you like the vids. :)
I'm a welder and i say you can't weld that. It will break of. Good video.
Yes, as well as breaking the alignment is critical so you would need to build a jig first and even then I'm not what caused it to happen in the first place (an therefore happen again as you say)
Well the engine housings are usually made out of metal alloys not a metal it self, so welding it would probably make a big mess.. Aluminium with some combining components are used in these engines.. Aluminum can be welded by a fast and alu educated welder, but if it is alloy you cant weld it no matter how hard you try.. These engines are molded and drilled. Not everything can be welded. Aluminium and metal alloys are very hard to weld and combine.. They melt rapidly and are tough to control. Impossible to make a good weld by hand if it is alloy mixture. The thread you add will never combine the way the mold will. Your weld will break to hand force. It won't hold at all. Good video, make more of them :D
What confuses me is why are outboard motors so expensive? Did the mfgs collude and price fix? A motorcycle engine has 5 valves per cylinder. EFI and a lotta other goodies and yet still cost much less. 3k for a cylinder bore and pistons also seems INSANE to me. Maybe you should be in the cylinder boring biz me tinks ;)
I like the tribute display
:)
Dangar Mar
That's the spirit Stu, only one way to get over an old girl is to get a new one!
I’m at a crossroad right now on my 1990 Johnson GT 175 and it has a serious issue it won’t go over 38 mpg and I believe it’s the reeds engine is fully rebuilt and all new electric s and fresh plugs very well could be the carbs but at this point I’m lost I’m ready to sell it and move on to better things
I’m there, $100 for boat and motor. After watching video I notice my 1960s motor seems beefier, like starter motor bracket, but it has been stripped of carbs, coil, bug, wires, and cowling. Also notice my flywheel nut is recessed, seems the old merc was better quality at one time.
I definitely think all things are made more cheaply these days, and particularly out of thinner metal.
Hi stu.like your videos..very detailed ...i have a question for you : let’s Say you have an engine Like this in your video and in the midle of the SEA IT stops,and you Cant Get home Ulnes you can row like a m...f...my idea is to have a small 2,5 hp engine that you can easily put up so you dont have to row home....can you Then let that 2,5 hp lay down horisontally in the boat without IT being damaged or anything?it is a 2 stroke so maybe gasoline or oil will come out of IT or reach parts of the engine that is not good?
Tord from Norway
Aidan Thank you Aidan.I have done that....i did not want the motor to Lie loose in the boat and may do damage to the boat or motor.if i met big waves.....my boat is an Alicraft 16 feet.
hi im a new subscriber in your channel from morocco in north africa i admire what's you are doing i almost seen all your youtubes it's usefull im a bike mechanic i wonder if you need a help in your shop let me know
Hi Omar, glad to hear you have been finding the videos helpful. I want to get better at working on bikes so we might get to share knowledge one day! :)
lm glad you replayed so let me know when u r ready
nice videos . Love your work ! I want your opinion , is it easy to find a replacement block ? Someone is offering me a Yamaha 85HP two-stroke that has a hole/crack on the block , you can almost see the piston through it . I am still not sure is it a good project to start icebreaking with outboards . Thanks mate .
no1 fan from Malaysia
Hi mate, that's a tough call. You will almost never get a block from a wrecker that isn't already a complete engine (with the price tag that goes along with that). It would be interesting to see what a block costs from Yamaha as they do sell them separately. If you are interested in giving yourself a project to sink your teeth into it could be a good one, but it certainly wouldn't be simple one! :)
Nice, hopefully I'd see this video before getting into my adventure with my 1968 evinrude boat/motor combination. Actually it was running very well some times but one problem after another killed this idea. Hull and trailer was good like one on the video. In any case everyone needs a starter boat and all of us learn from mistakes.
For sure, the truth is that with many motors you don't know until you try. Some you can get running fine, some are more trouble than they are worth, but there is always another one around the corner.
I have been watching othe videos because I had to fix my wife car but love all your videos. And how many times have you jbwelded that bottom
Sailor Jerry's in the background! Sooooo Goood
I got a Johnson seahorse 5hp TN 28 made in 1953 still starts first pull after I rebuilt the carb . looks good on my 1955 John boat
Nice work, sounds like a great combination. :)
give it to burt monroe if he was still alive.
Carbies!
One of the best introductions on youtube. Great images , good sound, and brief.. very good,,
Wow, thanks!
Just a little tap tap tap!!... lol!! Great vid as always!
Thinking of removing our outboard it runs super great on land but bloggs non stop in the watet can't count on it ...it lets us down just don't want to deal with want to do solor electric troiler and pull the motor up to sell it...some outboards are non stop issues then cost of parts its a 1976
Yeah, they certainly become more trouble than they are worth in the end. The solar electric motor will be great for fishing.
hi mate love ur vids they have helped a heap over last 6mths with my new/old boat lol just wondering if u have a vid on dual battery setups ???
Not yet, but I do plan to put a second battery and a solar cell in the Green Machine soon so I'll definitely be filming it.
cheers bro
Love the videos. I collect antique outboard. Videos are very helpful. Keep them coming
Thanks Gary, glad you enjoy the vids. :)
special edition sailor jerry in the background at start good taste stu. thanks for the info in the other video about block tell tale help me out heaps
Thanks David, co-incidentally having a Sailor Jerry while I go through the comments. ;)
Great video again stu!!! Keep em coming mate!!!! You should smash a water jet pump in it! Have a good one mate! Cheers
Thanks Dan! The hull is almost finished now, looking forward to flipping it back over again. :)
I have a 04 Yamaha 4 stroke 25hp was running and lock on me now won turn any idea what went run
Hi mate ..great vids! Curious where are you? QLD? Im North of Bris near Bribie. Love some of your wisdom re Yam90 I just got.. not sure to bin it or try fix.
Hi Greg, in just north of Sydney. It is a tough call to know when to bin a motor or not. Even if you are doing all the work yourself, parts can still be expensive.
Dangar Marine cheers man. Was hoping you'd say Bris.. I'd offer you $$for hands on wisdom. Best of luck with your future vids. You've got a great demeanour and delivery man, matched with know-how. Many thanks!
Thanks for the great videos, do you ever consider the pollution that some of these old motors produce? I guess that goes hand in hand with fuel efficiency. I love recycling old stuff but like my (really) old truck that I kept fixing, it kind of bothered me that it was a bit of a polluter. I loved that truck and really miss it but the frame was rotted, and it was too old for a complete rebuild. So I traded it in.
I much prefer 4 stroke motors because of the pollution side of things. With regards to replacing the old truck or car, it turns out that the pollution created to make the new truck is much more that the old truck would produce for the rest of your life.
Yes, someone also said that to me, so we come full circle, it makes sense in some cases to fix what you have for environmental reasons. I am in construction, and have demolished several old houses to build new homes, and it was many large truckloads to the dump, really a lot of waste. So in a way, I am guilty! Thanks for the reply and great videos.
Great Work!! You got it to last long enough so you could get some use and now you can get a new one!! :)
I did get a few years out of this one and it was free given it had already gone under the water about three times before I got it. ;)
5:57..'Bout Ready to Go To One Myself! (REST IN PEACE!)
My condolences. I hope you find a great replacement.
I had to replace a belt on my 2005 Mercury but I could not find a new one at all, not even dealerships could order one. I only found ONE on ebay from some guy in Africa. So yeah with that kind of difficulty to find a part, my outboards time is almost up. :(
That's really surprising. 2005 isn't that old at all and I find American brands are normally good at stocking parts.
I'm just hoping that if something does need replacing its not hard to find.
Time to go Evinrude ETEC! Good tips on deciding if it's time to repower.
You sounds like Peddley. He's always trying to convince me to buy an ETEC! :)
We have been an Evinrude dealer for 50 years! We sell tons of them. We're also a Mercury dealer and sell lots of the 40-60 Four Strokes
Really have enjoyed all of your videos. Just learning how to fix my 3 outboards and your videos have helped! Thanks!
Thanks Greg, glad the videos have been helping you with your outboards.
Learned a lot and got all three of them working! Thanks again for sharing!
Can't wait to see the new donk Stu...Oh.. and the docking lights
Me neither, on both accounts. :)
i had the same problem on my catamaran yacht power cat 40 footer and the Yamaha Four Stroke Outboard 200 hp v6 3.3l and i was heartbroken when i had to give them up
Yes, it's a shame but as some point it just isn't worth keeping them going.
Yeah i sold them motors and went bigger becuase i wanted bigger more badass twin g2 300's on the back now now its going just under 75 mph with 20 inch 3 bladed stainless steel rebel props at 6000 rotations a min
w/ the old motors i got 47 mph with 18 inch three bladed stainless steels
Thankyou I will check the stat and let you know.
Dam i wish you had a shop near me (sydney) my 2004 Mercury optimax 150hp is having heating issues, impellar changed but no fixes yet
I would be looking at the thermostats next. Even if the pump is working well, if the thermostats are stuck closed then none of that water will flow through the head.
I've noticed that the tell tale takes 1-2min when the motor has started for water to flow out, and also the tell tale looks weak, anymore suggestions you could throw at me before i take it to a mechanic? thanks in advanced
Jay was it the thermostat?
On of those points is if it’s a Force. Replace it.
Cast is better brazed. Brazing-bronze will soak into cracked ferrite casts, and it'll be the last to break when you give it the right position.Carbs? No need to replace them. Boil them in the best dish soap and water for a couple of hours. Clean with a soft toothbrush when clean. Boil again, not too long, just until the next commercial... Rinse in tap water. Dry by air or low (140F) oven.
But those other problems? Those are death to the motor.
Love your videos. Thank you for all the great info. What are your thoughts on EFI engines? I'm specifically looking at purchasing a 15hp Suzuki outboard.
Discovered your channel recently. I really enjoy it. I just repowered my 2000 Lowe 1648 that had an original 1999 Mercury 30 hp with a new 2020
Tohatsu MFS 25 horsepower 4-stroke. I couldn't be happier!
I've just about had it with my Johnson! Lol! I have a 1977 Johnson 70 hp motor that's giving me fits! I've rebuilt the carbs, swapped out the reed valves, and found a weak coil which I replaced. My timer base seems to have a mind of it's own just taking off at random! I've made/posted 2 videos showing my problem. If you have 5 minutes to spare some day please watch "What's wrong with my Johnson?!! Part 1 and 2. Let me know what you would do! Cheers from Canada!
I will stick with my 1956 30 HP. Evinrude it will and out run a 40 HP. 1989 Evinrude on a16 ft johnboat!
feel for you and agree
Hi Dangar Marine i have a issue we my 1995 yamaha 90 2 stroke running foward they dont go more that 3500 RPM I remove the oil tank mixer i mix the oil we gas now ,i change the spark plugs i clean the carburattors ,i change the fuel line ,the prime i clean the little filter inside the motor,i check the fuel pump don have any hole on the diagfragm the compression on all 3 cillinder is 140 on each cilinder and is working better but not more than 3500 RPM, I dont know if is the CDI SAFE MODE or any other Issue,can you o any person here can help me PLEASE.
Thanks

Mine kind of guy! Boats and motorcycles! Ride on!
Thanks Anogoya! If ever I went cruising on a large boat I'd definitely take a motorbike with me. So cool for exploring any islands you pull up to. :)
I have a 1996 75 hp 2-stroke mariner , and it needs swivel pin bushings replaced. In your opinion is it worth all the work to fix ? Has 130 psi across all three cylinders, and good t&t , super clean under the cowl. but I know it has seen some salt water . What are the odds of tearing it down without breaking bolts ? Should I just run it as is ? Has lots of play .
The dog knows more than he's saying.
It's always the quite ones.
rebirthing of the green machine...I love it
Thanks mate, can't wait to get her back out on the water! :)
Dangar i like your videos and your honesty. i have a 1978 85 hp Johnson since new and its been on several boats. i rebuilt it 5 years ago the power head that is and taught myself to do it. i have spent 4 grand on this motor. i paid the dealer to completely restore the lower unit and electrical systems. he was reluctant to do the work and as you said he advised buying new. i explained to him that if it were a 1965 corvette would he refurbish it and he said of course. So i said well this is my corvette and i want it restored. He insisted on payment up front which i just reached in my pocket and handed him 3 Grand for his work. i have a lot of sentimental value in this motor. and it has been running for 4 years now better than new. The mechanic is always asking me about the motor as he said he never finds people like me who will spend money on old motors. he was also thankful for the job as he was able to train his two young techs on my motor so they could get the experience. thanks again for the great videos!
Hi, love your videos. How good do you think 1975 85hp evinrude is. Are they good motors that will hold many years? Are they reliable? Thanks!
That depends mostly on the condition of specific outboard and the life it has had in the past. As a general model though I think they were pretty solidly built.
Not sure what to take away from this video. You go on about how you did many half assed repairs and they are now showing up as unreliable. Maybe more time should be invested in an engine like this to do a proper maintenance and repair regimen..?? If you're going to do repairs on something that your life and those you love might depend on then would make an effort to replace parts with new, and if I have to make my own then I'm bloody well going to make it as good or better then the original.
Gday mate this is always a worry when you buy a second hand motor , you just never know if it is as good as the seller says it is when i bought a motor for the haines a 50 yam although there were a few cosmetic problems it seemed to be in half reasonable condition but i still did my own maitenance work on it to be happy in my own mind with it ,reliability is everything in an outboard motor if it isnt you will always have that nigling feeling about that problem "will that be ok ?,scrap it for parts try to recoup some of your money and move on is sometimes the best way .
Moby Marine will be right onto this one ;)
That would be nice! :)
Why do they make salt water machines from aluminium ? it corrodes faster than stink. Same goes for fishing reels
gently tap off they ends verry gentel indeed
Nothing is gentle in the world of corroded outboards!
Give up on a motor? Never ha! Unless its a salty i guess
Check out my chanel
+Rat Sleds This one sure saw a lot of salt during its life!
when the powerhead water jacket rusts through the cylinder wall, it's over
very nice shop to work in...
Thanks mate.
Hello Dungar Marine ,
My ? : My brother has a 1999 Johnson 150hp w only low hours ( about 100 or so ) , the compression was over 100 lbs. in all four cylinders , but now all four cylinders are showing only 92lbs on each one & he says it has a little jumpy miss at idle h
What r ur thoughts as to why this might happen to this 150 Johnson 99’ yr model : all four cylinders were
over 100psi & suddenly all four cylinders go down to 92 psi with a little jumpy back miss ! Why would You Say in Theory ( motor is used in a saltwater
bay well above freezing all year every year ) ?
JB weld man!
I could make a new outboard from JB Weld. ;)
Dangar marine do it
I fixed a chainsaw with JBweld still running to this day from two years ago
The main thing with JB Weld is to give it plenty of time to cure . On a fix like that one I would give it at least 2 full days 3 if you can .
Why don't you just throw a shrimp on the carbi? :o)
first + love you vids
Thanks mate. :)
I've heard from several people that mercurys are notorious for constantly needing work as they age but Yamaha is a way more reliable motor is this true?
I've personally found the Yamahas to be more reliable, yes.
I've personally found the Yamahas to be more reliable, yes.
Not much of a mechanic, but what to see what I can do about fixing my 2002 outboard 25 Mercury or to accept it as a loss. Newbie boat owner, did not realize on a 2 stroke I needed a mix. The motor is seized up now. Any advice or educational material you could recommend would be appreciated. I have the full motor manual and a decent set of tools and would like to learn how to fix this out on my own. If all else fails I can always take it in to a professional. By the sounds of it, is it a complete scrap or do I have a chance at fixing it? Im mostly worried about permanent damage, if I can unseize the thing. Thanks for any the info!
If it is still seized tight then it will need to be disassembled to see if there is damage to the cylinder walls. Often outboards will seize from lack of oil and free up again once they cool down. If the cylinder walls are badly damaged then it is likely to need to be rebored and over sized pistons installed which is pretty much what I did with the recent series of videos on the Evinrude 150.
