Default 3 or 4 blade props?

Hey Barry

I am basically am looking to be able to plain at a slower speed than I am
currently achieving. My boat doesnt like to hold a plain at under 25mph, and
when it gets rough, I'd like to go slower than bouncing from one wave to
another. And yes I am also looking to maximize my range.

Thank you all, I appreciate your inputs...

Rick








Rick,

Sounds like trim tabs would do more for you than changing props. Their is
probably no better way to achieve slower planing speed than good trim tabs. Of
course, that certainly won't be the most economical speed. Most new outboards
are most economical in the 3500 to 4000 rpm range.

At certain rpm ranges, I imagine a 4 blade could be more economical than a 3
blade but I'd still be real surprised if you took an outboard motor on a
typical v-hull boat and tried just to maximize the most mileage per gallon
possible that could be gotten out of that engine, a 3 blade prop would be the
winner.

What do you think, Tony?
