[C320-list] Water on floor by water pump

[Steve Martin]

We had similar problems two years ago, although our water (a) was more than your small amount and (b) pooled on the port side by the ladder, closer to the stove.  We ended up replacing the pump, which was clearly leaking.  It was really only noticeable when the RPMs got pushed up, so we'd most often find it after motoring in or out of the marina.

After shutting down the engine yesterday, I felt all around the water pump and various connected hoses with a paper towel, it came back dry everywhere.

The impeller was changed this spring. I made sure to clean the impeller cover and mating surfaces before putting in a new gasket.
