Good To Know
Q: Does this set include everything needed for a full top end rebuild? A: It supplies the gaskets and seals for the upper engine assembly, though fasteners and wear parts like pistons are typically sold separately. Confirm the set contents against your rebuild plan before ordering.
Q: Will this fit my specific Sea-Doo model? A: Fitment depends on the engine platform and model year listed, so verify your machine matches the 1630cc 2018 RXT, P, or XRS 300 before purchase. Serial number variations can affect fit.
