Since rebuild cost is close to cost of new pump, I'm going the new pump route since it gets me back sailing sooner. I'll get the old one rebuilt. thanks to all!!! Pete W. Siren Song '91 C&C30-2 Deltaville, Va.

So, I replaced the impeller [old one looked perfect after extraction] and the "O" ring seal. After renewal of impeller and "O" ring, I ran engine about 2 to 3 hours, and no leakage was observed. However, yesterday, it was leaking at about 10 to 20 drips per minute while motoring. Are these pumps similar to an automobile water pump? That is, when the auto pump's bearing fails, it starts to leak? Is the leakage telling me that I have a bad bearing in this pump?? Thanks, Pete W. Siren Song '91 C&C30-2 Deltaville, Va.
