Good To Know

Q: Is this gasket reusable if it looks intact? A: No, gaskets are single-use and should be replaced each time the housing is removed. Reusing one can lead to coolant leaks and uneven sealing.

Q: Will this fit other 1503 watercraft? A: It is made for the 1503 engine platform and pump housing configuration, so verify your model and serial number before ordering. Fit can differ between production runs.

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