hi i have a 1976 evinrude 35 , the problem i am having is that the engine even on full throttle is hardly pushing the boat along , the boat is a 14ft cabin boat , various friends have told me that it is the wrong prop (10x13 fitted) when i bought the engine a couple of years ago it had a brand new prop on it and now im just wondering if the guy just chucked any old prop on so he could sell the engine........please help
