[C320-list] Simple Hose Replace? - Between sea water pump and heat exchanger (resend w/o images)

[Joel Krauska]

Well, I replaced the hose, and it looks like it was never the hose, but
rather the pump.  I can now give the new hose a little squeeze and I hear
and see water coming from the pump.
(looks like at the shaft -- same issue as Doug reported just now -- maybe
it's something in the water! -- and thanks also Ted.)

I see a thread from last summer about taking it to a shop to have the seals
rebuilt.

Need to check prizes on replacements.

Doug: What are you going to do?

Best,
