Impeller for Yamaha/Mariner 6-8 HP (2-Stroke Models) – Durable 6-Blade Water Impeller

The 52.400.00 impeller is specifically intended for small Yamaha and Mariner two-stroke engines in the 6-8 HP range. It replaces the original water pump impeller (Yamaha OEM #6G1-44352-00, equivalent Mercury #47-11590M) and restores full cooling performance to your outboard. It is compatible with popular models like the Yamaha 6C, 6D, 8B, 8C and their Mariner counterparts that powered many small boats in the 1980s and 1990s. The marine-grade rubber construction ensures longevity and reliability without cracking or tearing under prolonged use.
By swapping out the old impeller for this high-quality replacement, your engine will once again maintain proper operating temperature. Installation is quick and straightforward – the new impeller fits exactly into the water pump housing. This ensures an optimal flow of cooling water to the motor, which is critical during high RPM operation and hot weather.
This impeller is a must-have spare for anyone relying on a Yamaha/Mariner 6 or 8 HP engine. Regular inspection (and replacement as needed) of the impeller will protect the motor from overheating and ensure trouble-free performance during fishing trips or boating excursions. Keeping a spare impeller on board at all times is an inexpensive insurance against costly engine repairs.

• Application: Ideal for small fishing dinghies, inflatable boats, and yacht tenders powered by 6-8 HP two-stroke Yamaha/Mariner engines. This impeller provides reliable cooling even when the engine is running at full throttle carrying heavy loads.
• Recommendation: Recommended for vessels up to about 3–4 meters in length driven by Yamaha/Mariner 6-8 HP (2-stroke) motors. Replacing the impeller every 1-2 seasons (depending on usage) ensures your engine stays properly cooled and protected.
