Sierra 18-3075 Neoprene Impeller Kit, Replaces Jabsco 22405-0001, for Volvo Penta Stern Drive

The Sierra 18-3075 is a neoprene impeller kit built to restore raw water flow in Volvo Penta stern drive cooling systems. The kit includes the impeller and gaskets needed to complete a water pump rebuild in a single service, saving a trip back to the parts counter for a missing seal.

The impeller itself is molded from neoprene, a synthetic rubber compound chosen for its resistance to heat, wear, and marine fuel and oil exposure, and it is rated for salt water use. It measures 2 1/4 inches (57.2mm) in diameter and 1 1/4 inches (31.8mm) in width, with 12 fins driving water through the pump housing on each rotation. The neoprene compound flexes to seal against the pump housing while resisting the set and premature cracking that lower-grade rubber impellers develop after repeated dry-running or storage.

This kit is intended for Volvo Penta stern drive units and directly replaces the Jabsco 22405-0001 impeller, so it drops into the same water pump housing without modification.
