[C320-list] Water Pump Repair or Replace Recommendations

[jim brown]

One option is to get a new pump and try to repair the old one. Good project to 
try and even if you screwed it up you would still be able to use the boat and 
have one good pump. If it worked well you'd have a complete spare. Probably 
easier to change the whole unit than just the impeller when that needs to be 
done (since the darn thing is backwards). Then put a new impeller in the other 
one at your leisure so it's ready to go in an emergency. Also, I always find 
that if I have an expensive spare I'll probably never need it (as I'm frequently 
reminded)

I'd do the job myself (particularly if replacing the whole pump), and I'm no 
mechanic.  The pump is easy to reach and has few parts.
