I have a 25hp Tohatsu, which is the same thing as a Nissan. I put a SS Solas prop 13 ptich, on about 3 years ago, but was not enough go power for me , so I traded a buddy with a 14'boat for his 11 pitch prop, and holy crap!!! Props are a good thing, but make sure you get the right pitch or you won't get take off, but might get top end, or might get take off and no top end, or when you hit the nail onthe head, it all works out like magic. I would not go back to any of the 3 aluminum props I had before this. i have hit numerous "things" (with the ss prop) in the white and Arkansas rivers, and only have a couple nicks in the 1 blade, wher eI had replaced the Al props 2 times. The only good thing about al props, is you can bend it back if it bends. But then again, if you bend a ss prop, you got other problems.
