[C320-list] JMP Raw Water Pump?

[islgirl3 at aol.com]

Has anyone had any experience using the JMP pump as a replacement for ;
Yanmar 128397-42500 , Johnson 10-24509-01, F4B-903Does it take the same impeller, o-ring etc?

The pump I have is leaking around the seal, I have the seal out but hate change the seal and still have a problem down the road.The bearings seem fine and no scoring on the shaft.
Thoughts?
