Good To Know

Q: Does this piston require any machining? A: No, this is a standard 81 mm bore piston designed to drop into a stock cylinder that is within specification.

Q: Can I replace just one piston? A: It is recommended to inspect all cylinders and pistons, as wear often affects the whole top end on a two-stroke watercraft engine.

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