Pitch/Prop size?

[gdean7]

Force 125 on a 19 Ft. Bayliner Bowrider Capri. I am pulling tubes and skis. Along with 3 to 4 passengers. anyone have any idea of what I could get for a prop?

Re: Pitch/Prop size?

Basically you need a tach to know what to get.<br />The Max RPM is 5500 on that motor. The closer you are without going over is what you want.<br /><br />Personally I think a 17 pitch is what you want. I know your boating at least 4000-6000 ft altitude and are losing power due to altitude. Me too. Make sure you have the right jets in the motor and you will be a lot happier.<br /><br />Heck if your not over reving a 15 would be better for hole shot/ski but not fast top speed.

I have the same motor an an 18.5' bayliner capri. The "stock" prop is an 15 spline, 13 1/4" diameter, non-thru the hub exhaust, 17 pitch 3 blade. <br /><br />I have a new prop on order, should have it tomorrow and I ordered the same.<br /><br />15 pitch will give you better pull from a standing start, 19 pitch will give you higher top speed but in the end Realgun gave you the best advice based on RPM.<br /><br />Jeff
