I sprung a leak in my raw water pump. It took a while to identify it. I noted some water under the cushion in the aft cabin. I thought it was the AC pan overflowing as the sump was clogged with that orange sludge. I cleaned it out. Still water under the cushion. I also noted a salt build-up on my battery charger. I cleaned it off a few times and could not see how it got there. It kept on showing up. My raw water pump had some rust stains on it. Then one day I was going to replace my impeller. I reassembled everything and started the generator. Lots of dripping under the pump. I removed the cover and checked to make sure the gasket was seated. It was. I reassembled and started the pump. Still dripping. I replaced the o-ring. Still dripping. I was about to reorder a new cover plate when I noted a needle like spray coming out of the back side of the pump, landing on the charger. I realized the leak was coming from the other side of the pump, not the cover plate. There is a rebuild kit or I can buy a new pump. Anyone have experience rebuilding or replacing the raw water pump on a Kohler 5E?
