Good To Know

Q: Does this sleeve come ready to install as-is? A: Cylinder sleeves are commonly finish-honed to final bore size after pressing into the cylinder, so confirm the required clearance and machining steps before assembly.

Q: How do I know this sleeve matches my machine? A: Compare the engine displacement and model year of your watercraft against the fitment list, and inspect the existing cylinder 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.
