Water pump impeller for Honda outboard motor from CEF Marine, model 500348, is a flexible impeller for the cooling water pump on Honda 8/10 hp 4-stroke outboard motors. The impeller replaces Honda OEM numbers 19210-ZW9-A31 and 19210-ZW9-A32.
The impeller circulates cooling water through the engine's cooling system. It is made of neoprene, also known as CR rubber, and is intended for normal operating conditions in both fresh and salt water. Neoprene is not intended for heavily polluted water containing, for example, oil or chemicals.
The outer diameter is 45.6 mm, the inner hole diameter is 16.2 mm, and the axial width is 14.8 mm. The impeller has six flexible blades and a key drive hub.
The primary application is Honda 8/10 hp 4-stroke outboard motors. The associated OEM numbers also appear on selected Honda BF and BFP models with other power ratings, where compatibility may depend on the full model code, gear housing, and shaft configuration.
