Good To Know

Q: What does a typical water pump kit include? A: This kit includes the impeller, pump housing, seals and gaskets needed to rebuild the cooling water pump on compatible Mercury outboards.

Q: How often should an outboard water pump kit be replaced? A: Most manufacturers recommend replacing the impeller every 200 to 300 operating hours or once a year, and a full kit rebuild is commonly done during the same interval.
