Thank you so much for this tutorial. Very straight to the point, highly educational, and easy to follow. The examples you give are perfect and I can honestly say that I now know the exact prop for my boat after watching this. If your shop was local to me, you would certainly have a new client for life. Keep up the great work guys!
Have to agree with Barry Bebenek; the most informative video on props I've ever watched.
My left ear loves this. My right ear is lonely.
i use to have 3 props for my boat . low pitch for fast acceleration went getting skiers up and/or heavy loads. medium pitch for all round use and a higher pitch when going out in to the Ocean because it go a LOT better gas mileage and range. Range is very important on the Ocean.duh
What boat you Running i have a 19 1/2ft Starcraft GM 3.4 3 liter OMC Out Drive i pull Tubers and Skiers i run a 3 blade Prop i can get up on plane in the blink of an eye my boat shop says you want a Brass prop better out the Hole and top end
@@garyburbank8895 we have not used brass in 150 years....lol stainless steel dude ......or NYBRAL which is a mix of nickel and brass ,,,,,brass alone is way to soft.......
This is THE MOST informative video I’ve watched on this subject. It’s all crystal clear now. Thank you so much for explaining so thoroughly. 🇨🇦👍🏼
Great advice. What about switching from a 3 blade to a 4 blade on a 30hp Johnson that is running a 10x15 3 blade prop. I do alot of small river fishing and need a great holeshot for that skinny water. Normally 2 guys and a livewell full of cats. 1754 Grumman mod v flatbottom
Run a 4 blade... They create more lift quicker
It's 3 am and I don't have a clue how I ended up here.
Wow Andrew now it is one year later and it is exactly 2:59 a.m. and I'm not sure how I got here either.
Wow it’s 3:19 am and I know why I’m here lol
@@mikencrew8885 And I'm back here 3 years later at 3 am
Great video you guys covered a lot I learned a lot... at least I feel I did watching this video thank you
Hi i wonder if I can ask you 1 thing.
Have a holland steel boat about 12 tonns.
New was whit 60 70hp and i dont know gearbox aksel and propeller.
Upgraded 1996 to volvo penta tmd31A ore tmd31B.
Papers on both in a 1 ownder sens 1981.
But this new propeller is wrong i belive..
Aksel goes stright back and on to a propeller.
I do have exact propeller diameter way, and I belive this pitch. Not really shure.
But I am out traveling whit the boat, but not in boat now.
But if you can help me whit ur knowdleg and smart brain, I send it to you all info i have.
Problem is when them goes from 60 70 ore 80hp 3selyndret diesel, TO A VOLVO PENTA DIESEL TMD31A.
Them sey from penta it is "probably" right.
But them alsow telling me that ore this spesific diesel engine goes lowest on diesel in like 3600RPM. YES 3600 RPM.
Have tryed that, but thats sucks and when i hsve had 100eds of diesel cars and engine over the time, I like it more about 1800 to 2400 at max.
1800 to 2200 is the same speed in knots. But low like 5.0 knots .
If I goes babans and drive 2400 ore say max 2500rpm. It will make 6 knots.
But some are noy right here i belives.
Can i get your thinking of this now after see ur awsome video ????
There is a tumb of roul that have to Spear so much spare over topp of propeller to floor of boat.
I think i heard this in european COUNTRIES hsve to be 10 centimeter??? From topp of blade to hull of boat ????
Maby more pitsh so i lower rpm more and can drive at 1800rpm like all european fishing boats ????
My boat is holland curtevene 950.
9.5 meter. 32 33 feet ?
It is a famely cruiser ore famely hollydays boat.
I Just made it over to cabin/aparmant on the sea. And pensjonist cos of a broken back.
So my dream for 19 years now have bean traveling down european waterways from norway to MIDELTERAINEN and around there.
And as a 40 year of have hsd diesel trucks and cars. IT GETS HARD FOR ME TO USE RPM THATS PAPER SAYS.
HAVE TO BE BETTER WHIT LOWER RPM ???
AND WHIT SAVING OF DIESEL???
PAPER FOR ENGINE ACTUALY SAYS GOES LOWEST CONSUME AT 3600RPM.
BUT THIS HAVE TO BE IN A PLANER BOAT ?????
SHULD BELIVE LOWER RPM MAKES LOWER CONSUME ???
I CAN BE WERY WRONG.
BUT HOPE YOU CAN SHARE SOME OF UR THINKINGS ????
HEAVY BOAT AT 12 TONNS ABOUT THAT ZISE.
BUT NO ONES CAN MAKD ME ANY RECOMENDINGS ORE ANYTHING.
SO NOW I KROSS MY FINGERS THAT YOU CAN GIVR ME SOME POINTERS.
WILL HAVE ALL SPEC AT ENGINE AND PROPELLER LITTLE LATER TO DAY.
AND NOW I AM IN HOLLAND THAT HAVE SOLAS PROPELLERS FOR SALES.
ANOTHER ONE, HAVE PROPELLERS MADE HUGE INPROVMENTS LAST YEARS??
I KNOW MOTOR THST WAS HERE BEFORE 60 70 HP ABOUT. SAY 80 TO BE SAFE.
BUT THEM SOLD ALL WHEN VOLVO PENTA WHIT PENTA GEARBOX SHAFT AND PROPELLER NON ONE CAN TELL ME HOW IT SHOULD BE.
ALSOW GEARBOX I DONT KNOW HOW THIS IS GEARED TOGETHER.
THATS SAYS ON THE GEARBOX MABY ????
I REALLY HOPE YOU ONE OF THIS DAYS IN FUTURE CAN GIVE me some pointer.
Will see after ur coment daily 😂🎉😂❤❤❤
Propp is 21 i tvink left Turned and some number for pitsh.
Have had some boats before. But use to go BETWEEN 6 7 8.
Not down in 4.5 to 5 on normal power.
If gives more power, the ladys Ass just going down and ur diesel consume gets way up there.
And all boat yards and shop all say strange, cos over power motor and still slow and not up BETWEEN 6 8 them say them belived i would get to be in that range.
Hello Family marine I have a 21ft fishing boat with F100hp efi merc it has a 13.25 x17p prop engine tops out at 5000rpm would you know if this is the correct prop for the boat thanks
This informative video is by far the most educational and precise detail 1,2,3 and why and what for boat propeller presentation that I have ever seen!!! (and I've watched and read numerous mercury and other brand boat propeller video and articles) Thank you kindly! Also might mention elevation and hot season and cold season performance limits on outboard motors.
Good day to you,for 26ft Pontoon 115Hp Suzuki what propeller you would recomend and what speed your expectation ?
very good explanation.
jussst a curious question but i have a marlon sp14 and honda 9.9 what is the best pitch for this setup ?
Can you please tell me what type of prop I should use on my Johnson 25 hp ac lightning seahorse?
Watched the video and thought it was great and decided Family Marine could help me with getting the right propeller for my boat. I called them several times on different days and all I could get is.... "leave a message"...... oh well.... Anyway, It is a great video and thanks for the info.
Even a blind squirrel finds a nut sometimes. Some useful information here presented with a good dose of BS. His description of "Forged" is incorrect. Cast would be correct as forged is a stamping process. Cast is a pouring of hot metal into a mold. Big difference! Silica in Aluminum does not necessarily effect the "flex" of a metal especially in a prop with such a short cord. Certainly if over done but his statement that a prop can be made cheaply by adding excess silica is silly. There just isn't enough material in a boat prop to make that much difference. It's the name on the prop that drives the cost up. Period! He never mentioned things such a cupping which can easily solve cavitation problems and solve that "hole shot" thing he constantly described while maintaining top end speed. (To some extent) I'm sure these points and others have been made below but who reads beyond the first page of any TH-cam video?
I agree if he doesn't know the difference between forged and cast I don't think he knows anything new.
He really had me cringing when he was talking about propeller "efficiency". I'd love to hear it explained again with some founding in science.
Good information .It is so hard to get folks to understand the truth. Everything is a trade-off in regards to performance. Nailed it. Only caveat OEM Aluminum props are Cast (exactly what process is ??) Liquid metal into a mold is cast. Solid using thermal and mechanical is forged. Those cheap props ? Cheap cast pieces welded together , not sure what to call that. Besides junk.
Oh yeah?..yeah!..golly jee..you betcha!..oh yeah?🤣🤣
I own a propeller repair shop and have to say this is one of the best videos I've seen to explain how they work to the novice boater
i agree that
Hi, I have Fiberglass boat 5.5 meters 650kg, on it I have Mercury Optimax 115hp, 2008. year with prop 13.25x17. maximum rpm is 5750 at speed 28knots. Can you recommend me another prop to get more speed at 4000rpm, because I ofen use it on that rpm with wife and 2 kids?
Regards
Forged metal is pounded into shape. Cast metal is poured into molds.
At 13:13, he says, " This is what we call a forged propeller".
As far as I remember, forging is heating it and bashing it with a hammer to form it.
Casting is a case of melting the metal and pouring it into a mold. This is the manner they make propellers either gravity fed sand molds or ceramic molds with a wax replacement or injection systems.
Really great video! Listening is the best advice. I have a 2001 Mercury 150 hp 2 stroke that will be installed on my 1981 Baja 16ss. What would be the best prop in this set up? Thanks.
HOW MUCH MONEY YOU GOT TO SPEND WILL BE THE FIRST MOST IMPORTANT QUESTION?
I've got a 17 ft boat with a 50 HP 2 stroke I'm happy with the wot rpm and top speed (5600rpm and 21 knots) but the hole shot is so bad, takes over 15s to plane, it bogs down at 9 knots and about 3 K rpm and just slowly climbs untill about 13 knots it suddenly jumps to 5 K rpm the nose is down ect , it's a 1.(5 gear ratio and I've put a 10 pitch prop on it
Now my left ear knows all about propellers. My right ear is still clueless.
Very good video ive owned 17or 18 boats so far always used O,E, M. Props prefer Aluminum as a safety feature of sacrificing a prop tp save my outdrive or lower end My preference has been inboard /outboard Mervruiser or Yamaha outboards yet ive had good luck with Nissan/Io gatsu products as well for overall reliability and maintenance although they aren’t the fastest motors in their class they have been a good value to me Ive always stressed the same thing to my freinds about the numbers on props you will. Gain one but lose the other in the process many of my boats hav been Ski boats for myself and my family as A Florida jud Waterskiing was a passion and as i got older i enjoyed a lot of wakeboarding as it was easier on my knees
I'd be embarrassed too, if I couldn't get her up in front of 13-14 people.
I see what you did there! lol
i get stage fright bro!
Evinrude and Mercury are both made in Wisconsin, with long traditions of made in America.
And guys like this chap really do know their stuff - generations of living in the details.
Even though now in Florida, still have kids in Wisconsin.
Currently in the process of replacing an outboard engine on one of my boats, and found this very informative,
reflecting back on propeller mistakes in the past - that he describes.
your 1/2 right lol.......evinrude wont be made anywhere ....BRP.....STOPPED PRODUCTION END OF THE LINE .....
technically evinrude plant was in waukegan , IL.
This is very informative if you can sit down and understand all the technical stuff. Thanks for the video
This is by far THE BEST tutorial I have ever seen on propellers. Not even in manufacturer's web pages you can find such a great information explained in such a clear way. Congratulations, keep the outstanding way of educating customer. I wish you had a branch in Texas.
I dont even own a boat and i found this pretty damn interesting.
Same here
Same !
I work in a boat shop. Came here for some added knowledge for the everlasting debate on which pitch someone should use. Awesome video, subbed and about to watch them all.
Appreciate your guidance. Well done and very informative.
I purchased a 2019 Sweetwater 2286 with 3 27 in toons. Rigged with a 150 yamaha. The boat turns 5700 rpm at 31 mph on a 16x14 black max alum. Prop. The boat as run weighs 3300+- lbs. The Yamaha is a F150XB. How would you prop this boat?
I would suggest a 15.75 x 13 pitch Yamaha painted stainless steel prop.
Very good video. Just for your information to Forged is the process of hammering a piece of red hot steel. As a blacksmith would hammer out a horse shoe.
Propellers are made in a foundry by melting aluminum or stainless steel and pouring it into a mold.
Many propellers and and hand guns are made in a molding process called loss the wax method or investment casting.
I'm sure there are videos on TH-cam about this process.
Not trying to knit pick
A lot of people are confused with the difference between foundry an forge.
Once again thanks for the great video,
This mess important. Engine RPMs, fuel mileage, etc. I agree, I want to get on plane easily and quickly, then level off. Tom, you're a long way from me, or I'd be a customer.
Your explanation on the nuances between blade types and factors was really well explained.
This kind of knowledge and customer service is priceless. I’m in the middle of buying a boat and it so far been an absolute horrible experience I’m almost giving up.
Yes give up.
This is the absolute best presentation I have ever heard on the subject of choosing the right prop & pitch!!
I wish you had been my dealer several years ago... The two I dealt with did not have a clue... :( .. I had to learn the hard way which cost a lot of $$$$ & time. This was a commercial boat also... Which resulted in lost revenue before I finally figured it out myself.
Thank you again for this excellent video!!! :)
Well wht would y recommend on a 87" Champion bass boat 150 marnier
Did you get a reply
I have a 2017 Sun Tracker 20ft fishing barge and I need to replace my prop. The current prop is eaten up by gravel. This was my “learning” prop, as I’m new to boat ownership. The motor is a 2017 90 ELPT CT 4S with a 16” x 13p p/n: 78114A45. I’m considering moving up to a 14” x 12p p/n: 8M0084491 4 blade prop. The pontoon holds 10 people and I constantly have 10 people, mostly large adults. Do you think that would be a good prop choice?
What size 4 blade mercury prop should be on a 18 ft aluminum boat with a 115 mercury pro sx . I’m turning 5400 rpm now. What rpm should it be turning?
Check with mercury and see what the max rpm is. Sounds like your in the ballpark with what you have now.
Hello, what type (3 or 4 balded) and which pitch (17 or 19) PROP would You recomend for a 1988 Bayliner 2250 Cobra with 5.7 (loaded weight 3KP) it has 260 HP ? I was searching at www for an answer for a long time and looks there is no real one answer. At the moment we do use 3blade 17 pitch and thinking going for 4blade 19pitch - we do think that would save some RPM and fuel consumption at the "cruising range". The question remain, wont we overload the engine ? what would be Your recomendation ? Thank You for Your help. Best regards from Europe.
Great work Tom! I am very much a "boat guy", mechanically inclined, and I learned more about props in your video than the rest of my life combined!!
Hi I yes got a 2006 evenrude 250HP e-tec on My 1997 Wellcraft 22ft My old Motor Had A 15x17 Prop The mechanic Did not Have other Prop He instalet The 200hp Johnson from my old Motor Prop he sey I need A 19 pitch prop is this Ok and will you recommend aluminum or stateless?
I currently have a mercury 150 4 stroke with a 14.5 x 19 mercury black max prop. I'm having issues with control at WOT. Chine walking.... I am near the top of the rev range but may have a LITTLE room to go up in RPM. I found a 13 x 18 pitch stainless. I'm wondering if this would help with control? My boat is a 19' bowrider but has a shallow vee. It seems lighter than my old boat which was a 1991 with a 4 cyl 3L Cobra and it was only a 17'. The boat currently does about 52 mph wide open so I probably can afford to lose a few mph.
Hi hello I wanna ask you if you can help me with my motor. I have a fiberglass 18ft 1998 Nitro. With a 1998 120hp tracker by Mercury and Manufacture top RPM is 5250
And right now I have a 14 inch 17 pitch and I roughly do top speed of 40-50 mph but I have a lot of problems getting out of the whole a 30 gallon tank on the back and 10gal live well on the back to what prop would you recommend on my motor

I have a bass tracker 16.8 with a 50 hp merc. 4 stroke. Running at 4600 ft altitude it only runs about 5000 - 5100 rpm. it has a 12x22 prop. what can I do to get more performance from this boat? Thanks ,Roger
So what is the correct size and pitch etc prop for a 1993 Maxum 1800 sr with 4.3 liter and alpha one gen 2 outdrive. I bought the boat in the fall and it had a very chewed up prop. It was an aluminum prop and I had to file it off to get the chewed up parts cleaned up enough to even test drive the boat. It seemed to have a vibration so we didn't push it too hard but it seemed really poor out of the hole so I didn't want to put any trust into the prop size that is on it.
One of the most informative video, on this channel that I’ve seen in a while.👍👍
Hi Tom,
We are creating a 'kayak' site for marine/boating parts and accessories to help people find the best deal vs. having to go to lots of individual stores to research - we may also provide links to content on youtube such as yours so people can also get advice.
What do you think about this idea? Do you think it is a good idea for yourself/your audience? We would like to get some feedback before we get too far down the road.
If you do like it, is it the kind of site that you would feel comfortable advising your audience to check out?
Thanks!
Cheers,
Steven
I need your help. I have a mercury mercruiser 1.7 liters 120 horsepower Diesel engine with alpha 1 gen 2 from 2001. What propeller do you recommend? The boat is a Angler 2100 Walkaround. Please I need your help.
We have a 19 cc Hurricane with a 4 stroke 2016 150 hp Yamaha, could you please tell me which propeller would work best for us? We want a Stainless prop as we moved to Florida from PA
A bad pitch generic prob like Michigan Wheel or Solas is just as bad as a bad pitched OEM prop on your boat...correctly pitched for you boat, a generic prop will perform just as nice as a OEM prop but will cost you less money. I'm not buying the OEM prop rhetoric.
I have a 350 Chevrolet v8 motor with an Alpha one tranmision and currently using a 23 Prop, not giving me enough RPM! what prop am I supposed to use for this motor and transmission?
Great informative video !! Thanks for sharing your knowledge
Excellent vid. Here's one... Two props, same pitch, let's say one is 8 in. Diam. by 8 in. Pitch and the other one is 8 and1/2 in diam. 8 in. Pitch. Does the boat go faster with more diameter?
so I have a 20' fishing Barge pontoon with an aluminium propeller that has an 11 pitch and 14 inch. this is for a mercury 60hp Bigfoot engine, this is what Bass Pro Shop. Which is the correct propeller for this engine?
Holy cow, does he know his stuff or what?! Wouldn't it be nice to have that personal experience when you prop shop?
ANY GOOD PROP SHOP SHOULD HAVE ONE GURU THAT CAN ANSWER ALL THESE QUESTIONS.....BIGGEST PROBLEM IS THE CUSTOMER WALKING IN WITHOUT A CLUE WHAT HE HAS OR NEEDS, NO OLD PROP TO MATCH UP OR A SERIAL NUMBER FROM SAID MOTOR,???? LOL " ITS A MERC 50 HP WITH A BLUE STRIPE " DON'T CUT IT....LOL
Not so sure about that one, did anyone catch about 5:50+ in video, he says that the pitch determines prop diameter?
If that was the case, how can you get a 12-1/2" DIA. prop in an 8", 13" and 15" pitch? ...it is still a 12.5" Dia prop.
OMG! I thought I wanted to learn more about props until I watched this. The problem is that the guy is too good at teaching and I didn’t know how much I didn’t know. Now I think I need to go vomit.
So here’s my new plan. I’m going to go to my local marina and just tell them what I want to happen when I throttle my boat and simply say “ make it happen”!
I’m sorta kidding and sorta not. This guy is really great at explaining stuff and he actually made me understand stuff I really don’t care to understand. I’m simply too busy being the best at what I do so I’d rather leave this stuff to the pros. Now having said all that it is good to have a little understanding so that you don’t get bullshitted by a money hungry Marina butthead!
Ok i have a 1988 mako 171 sport with 9o mercury elpto, i run wot 5ooo rpm iam about 33mph, prop is ss prop was 17 repitched to a 15 from what i gather to be able to push alot of weight i feel i need to reprop to get to that 5500rpm motor is 89 mercury elpto thanks for any help?
my problem with my boat was not sitting upright did have the take it to the lake and see for themself well it was fixed after that the 90 26-year-old and still get out and moves along had to take it in the fishing all-day switch to charge all batteries halfway across the lake the boat died lost power and the rpm raised
the place I had it in for new batteries put the wrong batteries in I was not the only one that weekend had the same trouble taking the boat back to were the batteries were bought he had given me a list of repairs before I had any done pick the boat up taking to another place the next day he plane and said the boat is fixed and 150 dollars he charged put the right batteries in the boat
What do u recomend for a 90hp 4 stroke 22ft pontoon with load capacity of 13?
what do you have now? what is the rpm wide open loaded with fuel and people? let me know ill tell you....lol
did you watch the video?
Nice!!!
Best prop for a 115 VMax SHO on a rubber boat of 6m? I am normally alone or 2 people max to go SW tuna fishing. thanks
best video ever
Tom need to ask you a ? Buddy i have a 2006 mercury optimax 150 what is the rotation of the prop ? Thank you for any help
Custom prop guys will cup, or take cup out to adjust the RPM.
Prop tuning is an art as much as it is a science.
the work done by hand is an art the pitch and rpm are a science..... yes grasshopper you are correct
21ft Maxum Sport open with the 350. Want more “hole shot” and don’t really care about go-fast.
Any recommendations?

Love this, we just sold our marina but still have a shop I really have to upload more videos
I wish you wore a mic so i could hear you.. road noise trying to listen while driving didnt work out.. i hear mumbling.
Fordged and cast is not the same!! Alu impellers are casted.
Hole shot and top speed are great, but what about fuel consumption and longer distance cruising?
good morning Tom THIS IS GREAT INFORMATION AND WELL EXPLAINED, I have a 2019 triton 18TRX WITH A 2019 MERCURY PRO XS 200HP AND I WAS THINKING ABOUT PURCHASING A ALUMINUM PROP WHAT WOULD BE YOUR RECOMMENDATION THAT WOULD GIVE ME THE BEST POSSIBLE PERFORMANCE AND HOLE SHOT
Aluminum. No. More like a 24-25 pitch tempest plus would be the best
I have a 2006 Mercury Bigfoot 50 horse four stroke. Has 11-pitch on it went down to the boat store and bought a 9 pitch.. it acts like a bad clutch. I have an 18-foot Bentley pontoon boat. And with the 11-pitch with for adults and two kids 4700 rpm 12 mph .so I'm going to purchase a 13 prop and we'll see how it goes. I think I'm going to be in the market of buying a 75 horse Mercury 4 stroke. Or find somebody that is willing to do a little Trading with my 50
i hope they are 4 blade props.
Hello i have Honda BF90 4 stroke installed on my 24 ft pontoon. I want to ask which propeller dimensions are better for my outboard. 13.8 x 13 4 Blade Mercury spitfire or 13.4 x 15 4 Blade Mercury spitfire ? I drive my pontoon very often loaded with 11 persons.
Some help ?
Hi. I like the truth you speak Sir. My question to you is do you have a prop for a 1986 85 horse 3 cyl, Merc Force engine. I could not find a prop number no place on it. But it looks more of a 12 inch then a 10. It is a aluminum prop. Better yet could you please sell me your preference on a prop. But now I did transfer the engine to a 1964 Sea King 15 foot boat. I had to use everything from the 17 foot Bayliner. My prop is chipped so very badly. I won't run it this way. Also I may need an impeller kit. It hasn't been run since 2002. I've bought the boat recently. Yes please always OEM from you. Or could I send my prop to you by mail? I build Custom motorcycles, not boats. So I know very little about boats. But I do compare my videos. Thank you.
Hi there. Very nice and informative video. I have a small rib, 4.5m, with an old mariner 40hp 2stroke. It really really struggles to come to a plane with two (large) people on board, and I would ultimately like to be able to come to a plane easy with 3 people on board. My top speed is 28 knots but I don't really care to go that fast with that small of a boat. My prop is a 13 pitch and I am thinking of going to an 11. Any thoughts? Thank you!
I would like to see if you could recommend the correct propeller for my boat. I have a 24' pontoon approx (1900 lbs) with a 60Hp big foot merc 4 stroke with a 10 pitch (3 people on boat at the time) propeller. It will rev out at 6300 rpm and 15 mph. Looking to go faster and not have to change motor. Possibly change propeller

How does ainboard outboard engine rated 170hp@3800rpm compare in relation to propellers vs something like a 170hp@6000rpm outboard compare. Leads me to believe inboard has way more torque down low. So could I push it with a higher pitch vs the outboard?
The aluminum prop is NOT FLEXING enough to LOSE 25% !! Put a prop in a hydraulic press and bend it 25% and it will STAY BENT if not SHATTER from the abuse. The Stainless prop is more expensive and thus has a BETTER PROFILE just as the OEM props have a better design than the "Grey" generic props.
Hello great info for beginners, got a question , just bought a used 2005 Bayliner 185 ,with MCM 4.3Lt v6 engine and alpha one stern drive , it came without a propeller , what is the factory specified propeller for it and what would you recommend , thank you much , Bob Alabama
Dear lord, all i want in life is a 250 Yamaha with the right pitch on the prop.
I have a stratos bass boat 15.5 feet long with Yamaha 55hp 2 stroke, I can't seem to get it on plane and rpm seems very low will downsizing my prop help? I'm almost thinking my timing isn't advancing. Just bought the boat runs amazing.
I have a 2stroke 85hp Johnson. What is the best pich for me ? 16ft skiff
Hey Family Marine!,
I have a 31ft. IMP Eleganza with two 454's, transmissions, and TRSdrives. 4,800rpms is about the limit on these. I've been running the stock Mercury Cleavers, right hnd., and left hnd. (1985)boat.
I hear from a number of sources that Mercury Mirage Plus 23p is a good idea to start with for better performance all around. Supposed to be faster on plain and better top end, so what do you think? I'd like to look at a graph and see if this is corroborated. Are there listings for older boats (stock) that relate to the newer tec. props.
I've heard TRSdrives can handle some more pitch that 23's, (Mirage Plus), if they, (the outdrives), are in good shape. Gonna rebuild them nice sometime this fall say, and have the gears & shafts cryo-hardened!
Nick: good comment. You might want to contact Mercury's corporate engineering dept.
Want more overall performance? Incredible Hole Shot with Blazing Top Speed? Go with a Stainless 30 pitch prop and Nitrous!!! The torque of the big block engines will turn those props while on a plane, the nitrous is only for hole shot to get on plane, adds about 100hp to each engine. When used briefly for hole shots no damage is done in the motor, that's only if held on until block overheats. Fix the actuator switch to the throttle 7/8 or better it's activated. Cruise at 5/8 throttle. We've done more than 50 boats this way, ultimate performers!
@@ceisarsrepair7958,
Thank you for the ideas. I've heard of some guys running higher 20's, and a guy that runs 30pitch's on there-his TRS's!
I'm gonna work these Mirage Plus 23's this year, then maybe experiment when I make everything back there stronger!
Probably next year for higher pitch experimentation! :)
Nitrous, (or blowers, or turbos), might be OK for my motors, but NOT for my Borg-Warner gear boxes right now! They are probably my weak link. Much more power now, their plates will just spin and get roaches out! I'm gonna rebuild them with carbon fiber packs this fall though! Outdrives I'm gonna rebuild too. Gonna have a good company in Chicago that I trust cryo-harden shafts & gears then, so long as them gears aren't too bad. That makes these TRS'S good for some more power I'm hearing. Way higher pitch, though. I think I'd have to get some high-end lowers! Some day, maybe, and I can raise my "X" dimension with them then, I guess.
Gonna put blowers on the 454's,
probably cheaper than scammin-up some 502's or bigger. My compression is stock (8 1/2 - 1), that's good for blowers, so I'll be thinkin that way. Haven't ever put Nitrous on anything! That could be cool! Gonna start lookin into that! Thanks for the ideas again!
@@oldnick4707 one thing you can do this year is just get the nitrous "cheater" kits, low cost, instal them and the high pitch prop. "Ease" on the throttle smoothly as you reach 7/8 where the nitrous helps you, just don't snap the throttle (like dumping the clutch in a car) that's what breaks components. We've had Alpha 2 outdrives withstand 1,200hp blown hemis, just smooth application of power, no snappy snap. You'll totally enjoy this summer for cheap. Nitrous is not some Explosive Volatile Rocket Fuel like most people think, I'ts simply a gas that breaks up the atomization of your existing fuel and makes your existing fuel burn more efficiently. Also be sure to go to your local small airport for 101 octane. 1 last thing (sorry😁), get a set of trim tabs or good hydrofoil fins for the drives. They cut your planing effort in half and increase top speed efficiency and turning by getting that hull up and out of the water as quick as possible. We did an experiment with a 21 foot cuddy cabin bayliner with a Mercruiser 5.0, we put a 35hp outboard on the kicker motor bracket. It took everything the 5.0 could do to get on plane, took over 60 seconds. Once on plane, we lowered the 35hp and started it, went to 3/4 throttle and lifted the 5.0 outdrive out of the water and shut it down, no drag. We not only stayed on plane but at full throttle we increased speed to 31mph.... with only 35hp!. This proved that all that horsepower is mismanaged just trying to get on plane, it can do so much more once on plane. That's why the 2 speed prop was designed and such a huge hit!
Have a Great Day!
Hi I have a Volvo - Penta 3 blade propeller on a chevy v6 4,3 motor which has a 14.3 x 21 propeller and is 18 ft long bow rider. I want to replace it with a 4 blade propeller to get more torque out of the hole and get it to a plane quicker. I am not concerned with top end so much as I am getting out of the hole faster. What size and pitch would you recommend?
I have a little old Honda 8hp 4 stroke on my 16' aluminum Sylvan. I'm looking at getting a new propeller because I cannot get the boat to plane out I tried all different trim positions and it won't do it unless I move myself towards the middle seat of the boat then it goes from about 6 or 7 mph bow sky high to about 14 mph and planes nicely, like a whole new boat! Thanks for this video.
I found your information on youtube. Very interesting! Thank you.
150hp and down= aluminium. 150 hp and up =Stainless!
I have actually a Mercury 150 hp VERADO 2008 on my 18 ft Crestliner Super Hawk 1800 boat driven by a Mercury 4 blades propeller # OA2184X 18P . I’ve always been satisfied. But I’m about to buy a Ranger 1850 MS equipped with a 150 proXS. The boat comes with a stainless-steel 17” prop but I prefer an aluminium propeller since I often go into shallow water (I had to change the propeller 2 or 3 times over these 12 years!!!). The Internet Mercury propeller guide doesn't work for my application. The information I’ve provide on their site is as follow: boat is 2265 lb, people and gear are 850 lb, motor is a 150 PRO XS with a 2.08 gear case, 34 gallons fuel tank and I'll go for general good performance.
What would be good choices for an aluminium propeller for this dream fish and family ride boat. Is a 19” Spitfire Aluminium propeller would be a good choice? Or a Black Max 19”?
PLEASE HELP!
Thank you!
I have a 2005 Bayliner 185 with a 3.0 Mercruiser. What would the optimal propeller be for my boat. Im more concerned about holeshot than top end due to pulling skis
Do you have a tachometer installed on the motor?
Thank you for the information. On the FIRST example with the generic vs Yamaha prop, you don't explain the physics of what you say is a "cheap" prop. Price and money are not variables in the physics of how a prop work. What was the "design" difference?
when you say RPM's, do you mean propeller RPM's or engine RPM's? Are they the same? I would think there would be some ratios involved but as this question may lead you to determine, I'm very ignorant on this issue.
BSM1989 engine rpm
Currently there aren't many if any motors equipped with prop speed sensors.
Engine RPM
@@ceisarsrepair7958 That's determined by the gear ratio...unless you're running a V-drive with a transmission.
I gained rpm but lost top speed ??? Im wondering if i am down a cylinder??
I have a 20’ open bow with 305 V8 228hp use it for skiing , tubing, kneebord mostly but also cruise around. currently running 14.5x17p 4 blade and it gets out good and top speed 46 at 4800rpm would going to 19p be a good idea and if so should I stay with 4 blade or go to 3 or SS? I would like a little more top speed but not drop to much low end any suggestions? Thanks
Hello
Odds are that the maximum Manufactures recommended RPM on you engine is 4800. If the 17 pitch allows you to reach 4800, Wide Open Throttle, light load, stick with the 17. If you are over 4800, then you can go up to a 19 pitch. A 3 blade stainless will only increase your top speed by maybe 1-2 MPH, however you may loose a small amount of hole shot.
