Yanmar 3ym20 pre mature water pump failure
I have a 2 1/2 year old 3ym20 with about 400 hrs on it. After returning from a six week cruise I found the raw water pump leaking. I thought it was the hoses but it turned out to be the bearings in the pump itself. This seems to be a bit early for a water pump to give up the ghost. Any one else have this problem ?
