Fellas, I need a water pump impeller for my Majestic 7.8 hp probably a 1954-56 motor. Has anyone found a source/modification of existing etc. impeller that would work on this motor. 1/2" shaft 1,5/8" diameter and 5/8 " deep
Many Thanks
Mike
I have a 1956 7.8 Majestic and I used a Sierra 18-3008, it was a little fat and I sanded it some. Also you need to drill a hole for the pin that goes through the shaft. When I got through it pumped real good and I got 18.3 MPH on my test run.
