Sierra 18-3251 Water Pump Kit for Chrysler/Force Outboard Motors 85-150 HP

The Sierra 18-3251 Water Pump Kit is a complete water pump rebuild kit designed for Chrysler/Force outboard motors. It supplies the core wear components needed to restore proper cooling system operation, bringing the pump assembly back to reliable working condition rather than requiring replacement of the entire pump housing.

The kit includes an impeller (18-3017), a wear plate gasket (18-0416), a water pump upper gasket, a water pump plate, and an O-ring (25-69202). Together these components address the parts of a water pump assembly that wear out or lose their seal over time from heat cycling and impeller rotation, restoring correct water flow to the powerhead.

This kit fits Chrysler/Force outboard engines rated 85 HP (1989 model D, F, G, and H), 90 HP (all model years except 1995-1997 and Sport Jet), 120 HP (all model years except 1995-1997 and Sport Jet), 125 HP (1988-1989), and 150 HP (1989 and up). Because fit is specific to these engine and model designations, confirm the part numbers on the existing pump assembly before ordering.
