More about this item

EMP 46-07415 Water Pump Kits

The EMP 46-07415 is a complete impeller service kit for MerCruiser sterndrives equipped with the brass sea water pump. It fits MerCruiser MCM V6 and V8 engines from 2000 and up, covering the 305, 350, 496, and 502 cubic inch displacements. The 4.5L and 6.2L MerCruiser engines are excluded from this fitment. If your MerCruiser falls into one of those covered configurations and runs the brass sea water pump, this is the kit for the job.

This kit is a direct replacement for Mercury/MerCruiser part 47-8M0137219. It includes a shorter heavy-duty impeller and an overmolded inner wear plate for the front of the sea water pump impeller housing. That wear plate is the detail that sets this kit apart from a basic impeller replacement. The front face of the impeller housing is a common wear point on these pumps, particularly on engines that have seen debris ingestion or extended service without impeller changes. Installing a fresh impeller into a worn housing without addressing the front wear surface leaves cooling efficiency on the table. This kit handles both in one service.

The raw water pump on a MerCruiser sterndrive is the engine's first line of defense against overheating. It pulls raw water from outside the hull and pushes it through the heat exchanger or directly through the engine block depending on the cooling system configuration. The rubber impeller is a wear item that hardens and loses its vane flexibility over time, reducing flow volume and cooling efficiency. A failed impeller can leave a V8 MerCruiser without adequate cooling in minutes under load.

Water pump service on MerCruiser sterndrives is recommended every 100 hours or once per season, whichever comes first. Given what an overheated engine costs to repair, a fresh impeller kit every season is one of the better investments in a MerCruiser's long-term health.
