1975 SF20 Repower - Prop Suggestions
 

I'm changing power from a 1989 Yamaha 130 to a 2003 carbed 2 stroke Johnson 175. I was running about 42 mph @ 5300 with a 13 1/2X 19 prop. Anyone out there running a similar Johnson 175 - what prop are you using and what kind of performance can I expect ? Thanks
