Description
The ProX Piston Kit for Sea Doo 951 0.50 is a half millimeter oversize kit aimed at engines that need more than a light hone but do not yet require the largest overbores. This size is frequently chosen when moderate wear, scoring, or several seasons of heavy use have taken a toll on the cylinder. ProX manufactures this kit to OEM style standards so 951 engines can continue to deliver the strong performance riders expect.

With proper machining, this ProX kit can help restore lost compression, reduce piston slap, and improve throttle response from idle through top end. The ring set is designed to seat correctly in a suitable cross hatch pattern, supporting durable sealing and reduced blow by. Riders can enjoy a more responsive, reliable engine that feels closer to its original character.
Always partner with an experienced machine shop for the overbore, verify all measurements, and inspect bottom end components such as crank bearings and rods. Use new gaskets, fresh fluids, and follow the service manual torque and assembly procedures carefully. After a controlled break in period, the ProX 0.50 mm oversize piston kit can provide many more hours of satisfying Sea Doo 951 performance.
