Prop pitch

Rate this topic

Go to Yamaha's website and search the performance bulletins for a similar boat (length, beam, deadrise, and weight) and engine. They will give the prop specs that was used - rest assured that it was the optimum for the application.

 

BTW, you can deviate on the pitch slightly to tweak performance for greater low end power or for high-end speed. Both are mutually exclusive.

got it thanks, apparently with my exact boat.....it's a 19 pitch that was tested, which is the exact info I was looking for. I don't know how I missed the Perfromance bullitin on their website- it was right there.

theres a bunch of online calculators that can give you "advice" on what prop is best.... basically, if you decrease your pitch by one size (usually 2 degrees) you pick up 2-400RPM on the top end; it also revvs easier as a result. I just got done dinkin' around with my prop....its tedious and can be expensive, so choose wisely. ask LOTS of people is my best advicecwm15.gif
