Compatibility

Parts Desk Insights
Best use case: Piston kits are a core component of any outboard powerhead rebuild — used when pistons show signs of scoring, ring wear, or seizure damage, or as part of a scheduled top-end overhaul. WSM is a well-regarded aftermarket supplier for PWC and outboard engine internals, offering a cost-effective alternative to OEM piston assemblies. When rebuilding a powerhead, always measure cylinder bore for wear and taper before installing new pistons — if the bore is out of spec, honing or boring will be required before the new kit can be fitted. Confirm model year and serial number compatibility before ordering, as Yamaha outboard piston specifications vary across engine families and production years.
