Good To Know

Q: Are these piston kits compatible with supercharged Sea-Doo engines? A: No, these are designed exclusively for non-supercharged (non-SC) models. Using them on a supercharged engine can cause failure.

Q: Do I need to bore my cylinders to use these pistons? A: Yes, these .020 oversize pistons require the cylinder bores to be machined to 100.5mm to achieve proper clearance and ring seal.

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