[C320-list] Maint list

I think that winter storage in cold climates may take a toll on impellers that can't be measured just by counting hours. When our boat was on Lake Ontario the blades would harden up over the winter and take a kind of hard set. I think the antifreeze stuff might also make a difference. Changed it every spring--not in the fall! Here in NC they seem to last longer. Maybe just my imagination however.

Very embarrassing for the seller (a good friend of mine). I learned a lot about sailing her that day. Turns out the annual replacement had not happened yet. We have replaced it at spring commissioning ever since.

Turns out there were 7 blades from 3 impellers (different colors) from the previous owner. They had just worked into a configuration in the front of the heat exchanger that blocked water flow. I resolved to change every year.
