Description
The CP Carrillo M9064 forged piston kit is engineered for Sea Doo RXP 300 and other 1630 Ace based models using a 100mm standard bore and 69.2mm stroke for 1630cc of displacement. With an 8.45 to 1 compression ratio, this kit is optimized for high boost supercharged use where managing cylinder pressure and heat is essential. It replaces factory cast pistons with a much stronger forged design capable of supporting aggressive performance tuning.
Each M9064 piston is designed to work with rod 9086, 866 2250 20CP3C wrist pin, 866×063 SWL locks, and CPN 3937 ring pack. The forged construction, strong ring lands, and carefully contoured crown help the engine maintain reliable combustion and ring seal under heavy load. This makes the kit a natural upgrade for riders who push their 300 horsepower Sea Doo platforms hard in real world conditions.
