Engineered Marine Products 46-46633 Marine Water Pump Housing

Engineered Marine Products (EMP) part number 46-46633 is a replacement water pump housing designed for Mercury and Mariner outboard engines. EMP manufactures aftermarket marine water pump components built to OEM specifications, offering a reliable and cost-effective alternative to factory Mercury parts.

The water pump housing is a critical component of the outboard's raw-water cooling system. It encases the impeller and directs water flow through the engine to prevent overheating. Replacing a worn or cracked housing restores proper sealing and cooling efficiency.
