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

[Joe Geiger]

Hi Joel,

I had the same issue and it’s the result of a worn shaft or bearings to your seawater pump. You can:
- Get a rebuild kit for $75 that will replace all the innards of the pump except the shaft. 
- Replace the entire pump (between $200-$550).  

If the shaft is scored or damaged then your only option is to replace the pump. That’s what I did.
