I have an 89 242ss with a 350 and i am looking for the best all around prop. I don't do any water sports I am looking for what's going to get me the best mph.

3 blade 18-19 mirage,is what I had on my 242. However I traded for 4 blade rev 4, needed hole shot and ability to get on and off plane for boating in Lake Erie!

A 19' mirage plus with a stock motor. If you have enhanced the torque curve you might be able to use a 21" but with that combination thats about the best you can do...sorry...no magic bullets for that one.

Thanks guys I will look for one
