Specs At A Glance

Good To Know

Q: Does this gasket fit both the RXT 260 and other 1503 models? A: This gasket is listed for the Sea-Doo RXT 260 1503 from 2011 to 2016 and cross-references OEM 420950820. Confirm your model and serial number before ordering.

Q: Should I replace the valve cover gasket every time the cover comes off? A: Gaskets can compress and harden over time, so replacing it when the valve cover is removed helps prevent leaks. Always inspect the mating surfaces for damage during installation.

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