Description
The CP Carrillo M9041 forged piston kit is aimed at Sea Doo RXP and related 215, 255, and 260 4TEC engines that need a substantial 0.5mm overbore and a low 8.2 to 1 compression ratio. With a 100.5mm bore and 63.4mm stroke for about 1508cc of displacement, this kit restores heavily worn or damaged cylinders while delivering a boost friendly compression spec. It is an excellent foundation for high boost builds where cylinder pressure and heat must be tightly controlled.
Each M9041 piston is included in the CPK9041 configuration and is designed to pair with rod 5476, 905 2250 19CP3C wrist pin, 905X073 SWL locks, CPN 3957 ring set, and H30220305 gasket. The forged design features strong ring lands, a robust crown, and skirt geometry tuned for stability at high rpm. This combination supports serious power levels and hard use in demanding marine conditions.
- Application 2005 2015 Sea Doo RXP 215, 255, 260 turbo engines requiring a 100.5mm 0.5mm overbore.
- Compression ratio 8.2 to 1, ideal for high boost and advanced tuning strategies using proper fuel.
- Forged oversize pistons bring major strength and reliability improvements over standard cast parts.
- Designed for use with 5476 rod, 905 2250 19CP3C pin, 905X073 SWL locks, CPN 3957 rings, and H30220305 gasket.
- Engineered for strong ring control and crown integrity under extreme load and temperature.
- Targeted at serious performance and race builds where the engine will be pushed to its limits.
For Sea Doo 4TEC projects that require a half millimeter overbore and a low compression, boost ready forged piston, the CP Carrillo M9041 kit is a top tier choice. It provides a strong, reliable base for making big power on the water.
