Replacement piston ring set for Sea-Doo 1503 4-Tec engines, sized for 0.5mm oversize pistons and cylinders. Worn rings lead to low compression, loss of power, hard starting and increased oil consumption. A fresh set of rings restores the seal between the piston and cylinder wall.

Before You Order

Measure the cylinder bore before ordering to confirm the correct size. Oversize pistons and rings require the cylinder to be bored and honed to suit, and piston-to-wall clearance should be checked by your machinist. Always check ring end gap before installation.
