Specs At A Glance

Good To Know

Q: Does this gasket fit other Sea-Doo models with the 1630 engine? A: Fitment depends on the model and year, so confirm your machine uses the 1630 engine and matches the listed application before ordering.

Q: Should I replace the gasket every time the throttle body is removed? A: Replacing the gasket during throttle body service is good practice, since a reused gasket can leak and cause idle or performance issues.

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