[C320-list] Simple Hose Replace? - Between sea water pump and heat exchanger

[Doug Treff]

Joel, 

I had the same issue a while back. I replaced the hose with the OEM part from Yanmar. Same thing. Mine was the factory original, painted to match the engine. In the end, in still had a leak. Turned out to be the water pump. I replaced it with a new pump and the leak stopped.
