Prop for Bombard Aerotec 420
I seem to have gotten my prop messed up (the rubber hub) and I'm thinking about changing it since it's only $50. And I'm not expecting the USD to come up any time soon.
However, I felt like I should do something different while I'm at it, and perhaps get a bigger prop. I have a 15 hp evinrude from -78, and it now has a 10" pitch. It's available with 11" pitch, so that's what I'd like to get. How does this sound? It's pretty slow now, even though it sounds loud and goes on a high rev. 14 knots even if I only measured in a strong current (up streams).
And also, it's available in 3 or 4 "wings", what's better?
