WINGOGO Johnson/Evinrude Impeller Repair Kit
This WINGOGO water pump impeller repair kit is designed for Johnson and Evinrude OMC outboards, covering a broad range of HP and V-series engines. The kit notes multiple interchangeable part numbers, including 05001595, 0435929, and 05007972, among others. It’s positioned as a straightforward rebuild option to restore cooling efficiency in V4, V6, and V8 configurations. Compatibility should be verified by cross-referencing model year and horsepower to the listed interchangeables. The kit aims to simplify maintenance by including the essential components to replace a worn impeller and associated housing elements.
Key considerations: confirm part number accuracy, inspect the drive cavity for wear, and verify that the included housing and gaskets match your engine layout. The listing suggests contacting the seller with year, horsepower, and model for compatibility confirmation.
QUICKMARINER 0395289 Impeller Service Kit (20-35 HP)
Designed for small to mid-range Evinrude/Johnson outboards, this kit targets 20 to 35 HP models with crossflow and loopcharged configurations. It replaces multiple OEM and aftermarket parts, including Sierra and Mallory equivalents. The kit’s breadth makes it a practical choice for owners who want a single solution for several compatible engines. Always validate the exact horsepower and model year, as cross-compatibility can vary across production runs.
Key considerations: check for the included impeller, seals, gaskets, and wear plates, and ensure the kit covers your motor’s specific cooling path. If you own a pre-1996 model, verify that the kit aligns with the correct configuration for your engine.

Designed for Johnson/Evinrude 9.9 to 15 HP outboards from 1974 onward, this kit includes a housing and a complete set of impeller-related components.

GHmarine’s kit targets higher-horsepower Yamaha outboards from 150 to 300 HP, offering a comprehensive impeller solution with an accompanying housing and related components.

This option suits boats that demand robust cooling performance in larger, faster-running engines.
Key considerations: verify the exact Yamaha model family (based on HP range) and confirm that the included housing fits your water pump cavity. The inclusion of multiple cross-reference parts supports compatibility across several aftermarket suppliers, but model-year accuracy remains essential.
Buying Guide: Key Purchase Considerations
- Engine compatibility: Cross-reference your engine’s horsepower, model year, and whether it’s a crossflow or loopcharged design to ensure the impeller kit matches your cooling path.
- Housing and seals: Confirm the presence of a compatible housing, gasket, seals, and wear plate. Some kits assort multiple gaskets and seals, while others are more focused on impeller blades alone.
- Interchangeability: Many listings show OEM and aftermarket cross-refs (Sierra, Mallory, GLM). Verify that the interchange numbers align with your engine’s OEM part or listing references.
- Parts completeness: A complete kit reduces the need for additional purchases. Check if the kit includes the impeller, ключ or keyway, gaskets, o-rings, seals, and a wear plate.
- Installation difficulty: Some kits come with more components than others. Assess your DIY capability or consider professional service if the housing alignment or seal seating requires specialized tools.
- Brand and supplier trust: Choose reputable brands or sellers with clear return policies and compatibility guidance to minimize the risk of incorrect parts.
- Maintenance interval planning: Impeller life depends on water conditions and maintenance schedules. Consider stocking a spare impeller or a full service kit for seasonal maintenance.
- Warranty and support: Review any included warranty terms or manufacturer support for post-purchase assistance if the part fails within a reasonable window.
