Good To Know

Q: Should I replace head bolts when swapping this gasket? A: Check your Sea-Doo service manual, as many head bolts are torque-to-yield and meant for one use. Using fresh bolts helps prevent a repeat gasket failure.

Q: Does this fit my 2014 RXT X AS 260? A: It is listed for 1503 engines from 2011 to 2016, but confirm your serial number and engine code first. Match the OEM number 420950772 against your original gasket.

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