This durable aftermarket water pump impeller works as a solid substitute for Mercury and Mariner carbureted 4‑stroke small‑horsepower outboards. It matches OEM part numbers 47‑16154‑3 and 369‑65021‑1 for direct replacement.
Built with premium marine‑grade neoprene rubber, this component delivers reliable tear‑resistance, stable anti‑aging performance and good salt‑water corrosion resistance under tough marine operating environments.
The impeller holds precise blade shape under ongoing rotational load. It effectively lowers risks of blade cracking, surface abrasion and irreversible shape deformation.
Every core dimension meets OEM specs, supporting fast and simple drop‑in installation with no extra adjustments. This part fixes common cooling‑system faults. These issues include engine overheating, inadequate cooling‑water flow and poor water output, which normally come from worn original impellers.
Swap your old or damaged impeller for this unit to restore steady cooling‑water circulation for your Mercury‑Mariner outboard. Apply professional water‑pump lubricant during fitting. Avoid running the motor without water source. Correct operation extends impeller service life and maintains dependable engine output while on the water.
