Hi Folks -
What is the correct prop pitch for a Tender 11 "Sport" fitted with an OMC 9.9 horsepower outboard?
Will upgrading OMC 9.9 to a 15 horsepower have any significant effect on performance, or is a 20 horse engine required to see any real change in performance?

With a 15hp Yamaha (tiller) the boat will hit about 26mph. At that speed the boat starts to dance because the middle hull is slightly bigger than the 2 outer keels so the boat tries to balance on the middle the end result is dancing buy it not that bad.Thats my theory.Every weekend there is about 3 of them in the bay near my house racing up and down.

I had a 11' Sport with a 15 hp, 20 hp, and 25 hp. I think the 20 hp is the best engine for that boat. I think the 15 hp is just a glorified 9.9.
