Good To Know

Q: Should I replace this gasket every time the throttle body is removed? A: Yes, gaskets compress and harden with heat cycles, so a fresh one is the safest way to avoid a vacuum leak after reassembly.

Q: Does this fit other Sea-Doo models with the 1503 engine? A: Fit depends on the specific model and year, so match your machine to the fitment listed above 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.
