This Water Pump Impeller for Yamaha/Mariner Outboard Motor is a CEF spare part for cooling water pumps on documented 2- and 4-stroke engines in the 115–300 hp range. The impeller replaces Yamaha references 6E5-44352-00 and 6E5-44352-01 and has CEF product code 500371.
The impeller is located in the engine's water pump and circulates cooling water through the cooling system. It has six flexible blades and is made of rubber/elastomer. The hub insert has a keyway drive. The impeller has an inner diameter of 22.4 mm, an outer diameter of 89 mm, and an axial width of 31 mm.
General compatibility includes Yamaha/Mariner 2- and 4-stroke engines from 115–300 hp. However, compatibility within this power range depends on the specific engine model, year, and OEM reference. Documented Yamaha models include C115, DX150, F115, F200, F225, F250, L130, L150, L200, L225, L250, LF115, LF200, LF225, LF250, LX150, LX200, LX225, LX250, LZ150, LZ200, LZ250, LZ300, P115, P150, P175, P200, PRO V150, PRO V150D, PX150, S225, S250, SX150, SX200, SX225, SX250, V6 Special, V6 Excell, V150, V175, V200, V225, VX150, VX200, VX225, VX250, VZ150, VZ175, VZ200, VZ225, VZ250, VZ300, Z150, Z175, Z200, Z250, and Z300 in the documented years up to 2005.
The impeller is also documented for Selva engines of 115, 150, 200, 225, and 250 hp with original reference 6E5-44352-01. For Mercury/Mariner, it is documented for the 225 hp 4-stroke engine with OEM no. 47-898689. The specification of 115–300 hp should not be interpreted as compatibility with every engine in the power range; OEM number, model, and year must match.
