SS vs AL prop on a 15HP 2 stroke?
I will be starting to get my 3m RIB and 15 HP Yamaha 2 stroke rigged shortly. Assuming that when I get everything dialed in, and the stock aluminum 9 1/4 x 11 J prop will allow the engine to run within the correct RPM range, would there be any advantage in switching to a Stainless prop? I'm a bit surprised at how crude the Yamaha prop looks, but perhaps it's not an issue with engines of this size.
