I just got a Key west 1720 with one of these, I'm coming from a 26ft CC and I was impressed with how this motor ran, was super fast to

[@Daphoid]

That motor sound / trim adjustment is childhood memory city for me. We had a few of them. Practical was a 40 hp on a pontoon boat. Fun was my uncle's 90 hp on a 13' fiberglass shell (no decking/bow covering - just the boat, some fiberglass bucket seats with boat cushions in them and some cut foam, and a rudimentary dash).

[@uhklixzy]

just bought a 06 90. The man had it garage kept, but kept it well maintained. Very pleased with my purchase. It's a beast!

[@pioneerz450]

Three cylinders and two stroke, this is how an outboard should sound.

i bought a 30 hp suzuki 2 stroke last year and it sanked in saltwater from a bad storm i rinse it all day with water and dry it put some new spark plugs and that´s it it ran like brand new still i love it

When I popped a piston in mine, I toyed with the idea of getting a new motor. Alas, there isn't another 90hp motor out there that comes close to the weight of the old Yamaha 2 stroke 90's. Just had mine rebuilt and absolutely no regrets. Love this motor.

[@InfoVblog]

Great Sound, I have a 2001 2 stroke 3 cylinder 90h. can only reach 5000 rpm SOMETIMES.. haha

[@Texcajun06]

If that motor is running properly, then your prop needs to be tweaked. Reducing the pitch will add RPM's.

[@sayaRiddles97]

It pretty cool that this single 90 hp can run trough the water that fast, may i ask waht is tonage of your Boat for this 90 hp engine and how efficient the fuel consumption is?

I got a 16.5 ft deepv center console with an F115 outboard, aluminium propeller 19 pitch original Yamaha. It goes 40 knots at 6300 rpm at full trim. It is mounted at the second lowest position. Motor has 5300-6300 wot range, feels fast but I think the last 400 rpms don't bring much speed. Should I go SS 19 inch?

Same angine on a yamarin 5120, I have a solas 13,5x17" aluminium but at my wot I can only reach 33 knots @4900, marsch speed at 26 knots with 4000rpm. Definitely not a good combo and I can hear that the engine is working a little bit too much, not easy to plan. Any suggestion? I still have to test a mercury 13x16 ss i have but I want a yamaha ss on next.

Good question I have to same combo and mine just revs to 4500 not much top end

[@330da]

Lift up your engine as high as possible on the transom ( new holes may be needed higher up for that ) Or use the simplest application to get that motor up,,after that,,test your 16” SS or a 15”SS

what is the maximum speed

[@Jetrider91]

You are pitching it a liiiiiiiitle too high. Upwardspray means not all power is dissipated into the water.

[@330da]

At the time i was using a,, Four Blade 13-1/4 x 18” pitch Propeller. The Stern Lifting Four Blade prop @ w.o.t + the high trim you can see in the video ,, got the 500kg Yamarin boat the highest speeds. The bow lift wasn’t there b. o. the oversized 18” four blade stern lifter. With this Boat and engine, i compromised Cruise speed over top end speed. Cruising 19 knots @ 2700rpm. With this carefully selected stern lifting 4-blade prop,the application has the best of two worlds. All the power are perfectly in the water. If you’re thinking of a random 3-blade prop,,then maybe you could be right. Have a nice day. : )

[@Number1Cowboy]

who told you a 4 blade was for fishing,,lol,,that is funny,,a 4 blade is for fast out of the hole but looses 3 to 4 mph on top end ,a 3 blade is slower from take off but is 3 to 4 mph faster than the 4 blade ,,I know this because I put them both to the test ,,so instead of a jack plate just change to a 19 pitch 3 lade and it will give you at least 4 mph more on top end ,,and trim it down a little more on WOT ,you loose forward thrust when you make a rooster tail,learn the proper trim

[@330da]

This four blade was the best of two worlds at the time,,,on plane,20 knots at 2700rpm,,just awesome satisfying cruise speed,,, and the fuel consumption,,,ear to ear smile Low.. On to WOT and tilt,,,that four blade sacrificed WOT top end speed for great low rpm cruise. The prop was a aggressive STERN lifting prop Not a BOW lifting one ,,,that’s why it could hold the grip without venting at that high trim ,,,I got out 37.5-38 knots that way and 35 knots at the “normal” trim.. That is so much to say about this topic and setups for what you want out of your boat performance please ask anything.
