Hello all,

Might have a problem.....

I have a 4.7 Trail craft with a 90 Suzuki four stroke top speed 55km with 3 guys + 120L of fuel RPM is 6200 glowing red, prop that I am using is (3451-139-17 Solas).
Any suggestion on how to go quicker or bring the RPM down?

Bigger prop maybe the answer?

Cheers

Yep. Go up in pitch to a 19".
