    which impeller for a 440-550

    I have a 1985 js440 that I put a js550 engine in with a 44 carb, high comp head, and half pipe exhaust. I still have the 440 pump in it. I have a 16.0 prop and a 17.0 prop which one should I use?

    I am with John on this. I pull a 17 with my 4mm stroker reed motor.
