I want to talk about the speed board problem

Do you do this with outboard fully trimmed down

THIS IS NOT GOOD IN ROUGH WEATHER COS THE MOTOR CANNOT HOLD THE WATER PROPERLY

Go down a pitch and add a blade, THEN tell me how good it drives and lifts after that.

Remember ..... the higher you go with that cavity plate ? The less water pressure you have for the water impeller pump to work efficiently !

great video

Flat out speed ..great !…cavitation..problems when choppy or rough conditions on turns …got a jack plate it’s all good..permanent mounting..not good idea…

*👍супер и привет от тренера по футболу!!*

Oliko nopeus tässä kohtaa 24 solmua ja kulutus 1,16L/1kts vai 1mph. Kierrokset näytti olevan 4200rpm. Yamaha 90 Aetol on huippuhyvä moottori. Paljonko tällainen moottori suunnilleen hörppii bensaa?

did you notice any over trim with motor raised? mine runs better raised but unable to trim up as far!

Sweetest idle of all outboards.

Looks to be about 3 or 4 inches too low..

But very bad in waves.. Not good..😅

get a permatrim...

Пусть покажет как на поворотах будет вести себя катер?

I spent a bit of time doing the exact same things for my 40 2 stroke suzy on my 18ft lund alaskan. i made a few vids on it. the biggest differences i found was swapping to a stainless prop with 1 inch greater pitch and motor height. also weight reduction. i went from around 26mph to 34.2mph after a few small upgrades. now im looking for a jackplate.

what size prop ya running there

Sweet👍🏻👌🏻

Super

Having a problem with mine going from neutral to forward stalling and the same from neutral to reverse. anyone know why?

That anti cavitation plate should be below water line so you can adjust your trim. That’s where I get speed and fuel economy. Please anyone correct me if I’m wrong. Safe boating 🇦🇺

once you get it up on plane you just trim the motor up a bit and play with the bow height. That will get more boat out of the water and you'll go faster, so you should be able to pull RPMS. If you are going to hit a rough patch of water and or do a sharp turn, trim down first and get the bow in the water for better control. Looked like the engine was in the perfect spot on that 4th hole, once you trim it out you'll pull RPMs and probably get like 5 more knots i bet.

The best engine/ transom height match is the one achieved when water flow skims right under the small upper plate. Raise or lower engine accordingly to match that given height and by visual inspection check if you're already there. Trim must be set at neutral along a perfect deck weight distribution. Once there prop will achieve the best prop thrust as there's more water level for blades to grab better on water compared to flow skimming around AV plate area. Once correct engine/transom height matched has been achieved, you should go for a prop maximizayion to a usually less pitch prop whether aluminium or SS ones in order for engine to rev at least middle to max wot rpm range factory stated and as usually loaded.. This engine/traansom match works very well in most water situations such as flat calm, windy, choppy conditions and at close tight turns at speed, be my guest and check if for yourself....

Да тут все понятно. Мотор 90 , ямаха. 😁

Love the steering setup clever innovation!!! Plus it hauls ass!!!!

someone at the marina suggested my motor is set to deep into the water.

احسنت

I have a Speedrace with a yamaha 6 and it goes as fast as that

Two things. Get that anti ventilation plate 1½-2" above the keel, and get that horrible alu prop off it. Find something like a Mercury Laser II for that boat. Getting the engine height right and the proper prop, you'll see at least a 4-5 mph gain in your case, with better overall performance.

умные ребята

if that boat came to you stock don't fuck with it if you want a high perform prop by one it's that simple

The thing is. Is that your under Erving the crap out of that 90. Those are meant to turn 5200-5500. At the rpm you are running at what I guessing is wot. You are way loaded up and that engine is going to toss a rod out pretty freaking quick.

хоть что нибудь по русски напишите, гады

BAD VIDEO FOR RACEBOAT THE MOTOR SHOULD BE 15+ GRADES UPP THE ANGEL IS SO WRONG ON FIRST PICTURE IT IS O DEGREDS ON PICTURES

Check to see if it cavitates when you're turning at WOT.

Help i cant turn off my 90aeto. recently changed the ignition solenoid so im guessing ive done something wrong there. switch and cut off was all working fine before

Thanks for the video and the test, it really made help for me. But is that the 90hp had the height hole to adjust? My 115hp seem didn't have that thing ... or I miss it?

Best video on yt

yes i agree…. great information on u tube to know what of an idea to perform at optimum out board motor height. thank you Salty Seaman.

I really like these 3 cylinder 2 stroke Yamaha, take a look at my 90 Yamaha 3 cyl kzfaq.info/get/bejne/m6x3hrKekp3Fj6s.html

Mahtava mootori! Since I was a kid, I´ve been in Finland each summer visiting my uncle near Vammala/Sastamala. He has always had Yamaha 2-stroke 90hp-engines on his boats, and every summer he takes us "Swedopelle:s" on a ride at Pyhäjärvi. Enjoyable moments.

Jack-Plate.

love the sound! same yamaha 90 hp

Fast and sweet! Good work Bud!

Love it!!!

what length is that boat?

what diameter and pitch is ur current propeller?
