Sierra Impeller Kit 223-3306, Replaces Westerbeke 46622 Generator Water Pump Impeller

The Sierra 223-3306 Impeller Kit is a replacement water pump impeller kit built for select Westerbeke marine generators. It directly replaces Westerbeke part number 46622 and is engineered to meet or exceed the specifications of the original equipment part it replaces, so the raw water pump continues circulating cooling water reliably through the generator's cooling system. The kit carries a machined exterior finish and is designed as a straightforward drop-in replacement during routine water pump maintenance or when an impeller has worn, cracked, or lost blades from age, dry running, or debris intake.

This impeller kit is compatible with a range of Westerbeke generator models, including both 60Hz and 50Hz configurations across the BEG, SBEG, BCG, BCGA, SBCG, BCGC, and BCGD series. As with all Sierra products, it is backed by Sierra's customer satisfaction warranty covering defects in workmanship and materials.
