Hi,
I have a three blade stainless prop, 14 1/4 x 17 along with a Permatrim which seems well suited for the motor (Yamaha 150hp) boat tops out at 5700 rpms and 42mph. It planes pretty quick now. I'm not concerned about top end. I am headed up north to a less sandy more rocky cruising area (Maine). I want to switch my prop out to aluminum and wondered if I used a four blade should I keep the diameter and pitch the same? I like the idea of faster planing and better mid range fuel mileage if you can believe the promotional advertising. Also when switching from stainless to aluminum with a standard three blade does everything usually stay the same with diameter and pitch?
