Water pump impeller for Honda 4-stroke outboard motor from CEF Marine is a spare part for the water pump in the engine's cooling system. The variant is CEF 500343 and is intended for Honda 9.9/15 HP with OEM reference 19210-ZV4-651.
The impeller is made of neoprene and has six blades. It measures 14.1 mm in internal diameter and 41 mm in external diameter, while the C-dimension is 28.55 mm. The drive profile features a keyway for a Woodruff key and must match the existing impeller and the engine shaft.
Compatible engine models
Compatibility includes the Honda BF8 8 HP with suffix C and CX, Honda BF9.9 9.9 HP with suffix AM, AX, B, BX and M, as well as the Honda BF15 15 HP with suffix AM, AX, B, BX and M. The engine's full model designation, suffix and original part number must be verified before replacement.
Replaces OEM numbers
The impeller corresponds to Honda OEM no. 19210-ZV4-651. Documented aftermarket cross-references include Sierra 18-3247, Mallory 9-45102, GLM 91009 and RecMar REC19210-ZV4-651.
The variant with keyway must not be confused with Honda 19210-ZV4-013 and item no. 52.326.00, which has a flat drive and a different internal diameter. The choice must therefore be made based on OEM reference and drive profile – not solely based on the engine's HP.
