Malibu & Axis Sherwood Impeller Kit – M5/M6 Engines (2018–Mid 2021)

Keep your Malibu or Axis wake boat's engine cooling system operating properly with the Sherwood Raw Water Pump Impeller Service Kit. Designed for select 2018 through mid-2021 Malibu Boats and Axis Wake models equipped with M5 or M6 engines, this kit provides the essential components needed to service the original Sherwood raw water pump.

The raw water pump impeller plays a critical role in circulating cooling water through your boat's engine. Over time, impeller blades can wear, crack, or lose flexibility, potentially reducing water flow and increasing the risk of engine overheating.

This replacement kit services Sherwood pumps G1502, G1503, G1503-01, G1503-02, and G1503-03 and replaces Malibu part number E100090.

Important Fitment Note: This kit is intended for boats that still have the original Sherwood raw water pump. If your Malibu or Axis has been upgraded to a Johnson pump, use the Johnson 09-707B-1 impeller kit instead. Verify the pump manufacturer before ordering.

Why Replace Your Raw Water Pump Impeller?

The raw water pump draws water into the engine cooling system to help regulate operating temperature.

As the rubber impeller ages, its blades may become worn, brittle, or damaged. A failing impeller can restrict cooling water flow and contribute to engine overheating.

For reliable performance, service the impeller every 100 engine hours or once per year, whichever comes first, following the applicable engine manufacturer's maintenance instructions.

Regular impeller maintenance is particularly important for wake boats that operate frequently during the boating season.
