[C320-list] Slow Leak From SeaWater Pump

[Doug Treff]

I had a similar issue - replaced mine with the YEU pump. Problem solved for about $200. The new pump uses different impellers and an o-ring instead of the paper gasket. So I also had to dump (sold online) all my old spares and buy new for my spares kit. The new pump moves a LOT more water. I'm assuming the old one was worn enough to affect the flow, even with a new impeller.

I have since replaced the impeller, the impeller cover, the seal washer that goes on the inside of the impeller, the O ring and the hose that goes from the raw water pump to the heat exchanger. I also used a silicone sealant around the O ring before tightening the impeller cover plate. It still drips. :|
