5001595 Water Pump Kit for Johnson Evinrude OMC 75-250 HP - Durable

Our review of the 5001595 Water Pump Kit finds it a practical repair option for owners of Johnson, Evinrude and OMC outboards in the 75-250 HP range who need a complete replacement lower-unit pump assembly without paying dealer prices. The kit includes a housing, neoprene impeller, gasket and wear plate, coupling assembly and all small parts, so the single biggest reason to buy is convenience: it supplies every component needed to restore raw-water cooling quickly and avoid costly downtime.

Key Features

• Wide compatibility: Fits a broad range of Johnson/Evinrude/OMC outboards from 75hp up to 250hp, making it useful for many multi-engine fleets.
• Complete contents: The package ships with housing, cup, neoprene impeller, impeller key, gasket, wear plate, O-rings, grommets, bolts and coupling so installers rarely need extra parts.
• OEM cross-reference: Replaces commonly referenced numbers such as 777802, 5551595 and 435929 so it can be used where those parts are specified.
• Neoprene impeller: The included impeller offers good pumping ability for routine cooling demands when installed with correct torque and seal placement.
• Cost-effective repair: Buying the full kit is a lower-cost alternative to dealer parts and professional overhaul while keeping the engine serviceable.

Who It's For

This kit is best for do-it-yourself boat owners, marine mechanics and small fleet operators who need a full lower-unit water pump replacement for Johnson/Evinrude/OMC outboards in the 75-250 HP range. It is well suited to people who want a single purchase that contains the housing, impeller and all small parts required to complete the job without scavenging additional fasteners or seals.

Those who should look elsewhere include owners with outboard models outside the stated horsepower or year range, and anyone who needs factory warranty parts or prefers dealer-only branded components; the kit is a third-party alternative intended for repair and maintenance rather than original-equipment reconditioning.

Pros & Cons

Pros

• Includes a full set of parts so the repair can often be completed in one visit to the workshop.
• Reported to fit as expected and provide solid pumping ability on compatible HP ratings.
• Good value compared with buying multiple OEM items or paying for professional replacement.

Cons

• Some users report sealability concerns and occasional loose fit of the impeller on the shaft, so careful installation and shaft inspection are advised.
