Re: Recommended Prop for 4.3L mercrusier I/O?
I had a 165 stright I/O when I got mine, it had a 15 1/5 by 5 and it ran fine, buty that said I needed a loy of hole shot caused I carryed a lot of weight.
Most boats here wil run a 17 pitch for good over all performance.
I have a 175 OB now and the motor came with a 19 pitch Stainless prod and it does well.
