Collection: Crankshafts
Crankshafts and crank assemblies for PWC engine rebuilds. The crank is the most expensive single component in most jet ski engines, and it is the part most often destroyed by problems that started somewhere else — water ingestion, a spun rod bearing, or running with contaminated oil.
Two-stroke cranks use pressed-together assemblies with rod bearings that require specialized tooling and truing to rebuild. For most owners, a rebuilt or new complete assembly is the practical path rather than attempting to true a crank at home.
We stock crankshafts and assemblies for Sea-Doo, Yamaha, and Kawasaki engines. Before installing one, find out what killed the last crank. Water intrusion through a bad carbon seal or a cracked exhaust will do it again to the new one within a season.
