Re: Prop Pitch

What rpm do you wish to turn the engines?
What is your gear ratio?

Have you run other props?
Is cruising or speed most important to you?

Re: Prop Pitch

I run w/ 23 pitch Bravo props.
My motors should run @ 5,200 RPM's.
Gear Ratio ? I don't know but I will find out. They are Mer Cruiser TRS Drives and transmissions.
