The prop needs to be matched to the engine.

So far the fastest I can go under power is 2.5 knots. There is a 2 bladed prop on the boat from the original atomic 4. Can i change the prop to a 3 blade or different pitch will I get more speed? The engine has a 2:1 reduction. ________________________________ Ahhh...imagining that irresistible "new car" smell? Check out new cars at Yahoo!
