Good To Know

Q: Does this sleeve need machining before installation? A: A cylinder sleeve is typically pressed in and then honed or bored to the correct piston clearance, so final machining is usually required. A: Have a machine shop check the bore and piston fit before assembly.

Q: Can I install this myself? A: Pressing a sleeve and setting the bore clearance calls for specialty equipment and measurement tools. A: Most owners have this step handled by a machine shop experienced with two-stroke watercraft engines.

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