Specs At A Glance

Good To Know

Q: Is this a bolt-on replacement? A: The assembly installs as a unit, but confirm the impeller pitch, seal, and driveshaft splines match your hull before fitting. Original fasteners can usually be reused if they are sound.

Q: How do I know the pump needs replacing? A: Rising RPM without matching speed, vibration, or visible wear ring scoring usually points to a tired pump. Measuring impeller clearance will confirm whether a replacement is due.

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