What the difference between the two motors, Most after market part #s are the same and a site called JOHNSON-EVINRUDE-BOMBARDER REMANUFACTURED POWERHEADS HAD THE 50,55,60, as the same head.
But when I checked on piston part #s, they do not match? I don't understand the difference in the motors or how this can be if that site is selling the same head for all three horsepowers.
I have a 1978 55 Evin and a 1981 50 Johnson. I think between the two I can get one good motor. Can this be done or am I missing something? I would like any advice and to better understand why the Horse power difference
