This water pump impeller for Honda outboard motors is a CEF Marine spare part with manufacturer number 500337. The impeller is installed in the engine's water pump, where it creates the necessary cooling water flow through the cooling system.
The impeller is made of neoprene with a plastic hub and has six flexible blades. The hub is keyed, so the impeller transfers rotation from the pump shaft via a key connection. The product is the impeller itself and not a complete water pump kit.
The inner diameter is 23.35 mm, the outer diameter is 87.8 mm, and the axial width is 31 mm. Please check these measurements along with the engine's original spare part number before replacement.
Compatible engine models
The impeller is intended for select Honda Marine 4-stroke outboard motors: BF75 and BF90 in the AV-AX series from 1999 onwards, BF115 and BF130 from 1999 onwards, as well as BF135 and BF150 from 2004 onwards.
Replaces OEM numbers
Directly documented Honda OEM references are 19210-ZW1-B02 and 19210-ZW1-B04. Honda 19210-ZW1-B04 is also a documented successor to the 19210-ZW1-B02 and 19210-ZW1-B03 revisions.
Cross-references and separate water pump kits
Documented aftermarket cross-references include Sierra Marine 18-3250, Mallory Marine 9-45104, and Recmar Marine REC19210ZW1B02. The Honda water pump kits 06192-ZW1-B00, 06192-ZW1-B02, and 06192-ZW1-B04 are separate complete kits with serial number-dependent application and should not be confused with this loose impeller.
