Engineered Marine Products 46-46634 Marine Water Pump Housing

The Engineered Marine Products (EMP) 46-46634 is a replacement water pump housing engineered to restore proper cooling system performance on compatible marine outboard and sterndrive engines. EMP components are manufactured to meet or exceed OEM specifications, ensuring a precise fit and reliable service life.

The water pump housing is a critical component of the engine's raw-water cooling circuit. It encases the impeller and directs water flow from the lower unit to the powerhead, protecting the engine from overheating. Replacing a worn or cracked housing at each impeller service interval is considered best practice to maintain peak cooling efficiency.
