Another prop question, need advise please.

[mogley]

My boat is an excursion made by forest river marine and is 19.9 long. I also have 4 stroke yamaha 90 and my current prop is 13.5/8x14 and my RPM at wot is 5400. I am looking to get closer to 6000 at wot open throttle. I am thinking just dropping to a 13 pitch, but hoping you guys might help me with recommendations.

Those are some nice looking toons

My 90hp Mercury Optimax (5000-5750)

In just went the opposite direction, I was running a 14 x 13p at 5800 RPM
And I switched to a
13.75 x 15p and dropped me to 5400

I would suspect going the opposite direction would work for you.

Nevermind, I found the pics... Sharp looking pontoon the dark and aluminum really look sharp together.
