Good To Know

Q: Does this pump come with a gasket or impeller? A: Confirm what is included in the box before ordering, since pump kits vary in contents. Replacing the impeller and gasket at the same time is common practice on marine cooling systems.

Q: How do I match my old pump? A: Compare the numbers stamped or cast on your existing pump against 21212799 and 3812519. Engine serial number and cooling setup can affect fitment.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
