I have a 18 ft CC with a 90 Yamaha 2strk on it, it currently has a 17p Aluminum prop. I get 5200 RPM with a full fuel load and 2 people on it which is my normal fishing setup, this gives me around 38mph GPS<br /><br />I want to get a SS prop and am looking for suggestions. I was thinking about a 15p Michigan Match and was wondering if that would be ok.<br /><br />Thanks<br />Rick
