Sherwood 15000K Impeller Kit – P151 Raw Water Pump

The Sherwood 15000K Impeller Kit is a genuine OEM Sherwood replacement impeller service kit designed for Sherwood P151 and 15000 G-Series raw water pumps. A properly functioning raw water impeller is critical to maintaining cooling-water flow and helping protect your marine engine from overheating.

This 12-blade neoprene impeller features a single key-drive design and measures approximately 2" wide x 2-9/16" diameter. The complete service kit includes the impeller, two paper gaskets, and one O-ring for servicing compatible Sherwood raw water pumps.

The Sherwood 15000K is commonly used on select US Marine Ford, Marine Power, Ilmor, MerCruiser, and other marine engine applications equipped with the appropriate Sherwood pump. It is also commonly found in some older Bayliner and Supra inboard boats.

On fresh-water-cooled engines, always confirm which pump and cooling circuit you are servicing before ordering.

Why Replace Your Raw Water Pump Impeller?

The raw water impeller is a critical maintenance component of your boat's cooling system. Over time, neoprene impeller blades can become worn, cracked, permanently bent, or damaged. A failing impeller can reduce cooling-water flow and potentially cause an engine overheating condition.

Routine impeller inspection and replacement is inexpensive preventive maintenance compared with the potential cost of an overheated marine engine.

Bakes recommends keeping a spare impeller kit onboard your boat, especially when boating in remote areas or during extended trips. A genuine Sherwood 15000K kit gives you the impeller, gaskets, and O-ring needed to service many Sherwood P151 applications.
