Re: 30hp etec prop opinions

So I found a 10 x 13 prop that I ran on the motor, gained 2 MPH, but also noticed an INCREASE in RPM from my test run with the 10.3 x 12. Load was comparable on both trials, same body of water, same water conditions.

I’m planning on bumping up to a 10 x 14, but was wondering if anyone had an explanation for the slight increase in RPM (I’m thinking that 1/4 inch decrease in diameter?).

I clocked the motor on 6 test runs at 5780-5810 with the 10 x 13. It was an aluminum too. Will and Fleetwin – I’m going to stick with an aluminum prop as per your recommendations for long-term gearcase health.
