This CEF Marine water pump impeller is a spare part for cooling water pumps on documented Mercury and Mariner engines in the 65–225 HP range. The variant is intended for select 2-stroke engines, including documented EFI and OptiMax applications, and is identified as CEF 500313G with reference 313.
The impeller has 6 blades, an inner diameter of 22.3 mm, and an outer diameter of 60 mm. The axial width is 33.8 mm, and the hub has profile number 12. Mounting is performed on a shaft with a key/keyway. A gasket for the pump cover is included.
The engine's HP rating cannot be the sole factor when choosing an impeller. Compatibility also depends on the engine series, serial number, number of cylinders, stroke, and existing OEM number. The variant does not have general approval for Mercury/Mariner 4-stroke engines.
