Good To Know

Q: What does a jet pump assembly do on a personal watercraft? A: It draws water through the intake and pushes it past the impeller to create thrust. A failing pump can cause cavitation, vibration, or loss of speed.

Q: Does this unit replace the entire pump? A: It is a complete jet pump assembly intended to replace the factory pump on compatible 1503 models. Confirm your model and year before ordering.

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