I'm waiting on the delivery of a new 14ft saltmarsh skiff and picked up a old Evinrude 15hp. It currently has a 9 1/2 x 10 aluminum prop. I ordered a tiny tach today and will see how it performs when the boat gets here. What I'm wondering is what options I have as far as performance stainless props in the small hp? Powertech SRT vs SWA? Sola? Ect.
