Independent Product Description
This durable marine water pump impeller serves as a reliable aftermarket replacement compatible with OEM part number 646‑44352‑00‑00. It is purpose‑built for Yamaha 2‑stroke 2HP outboard models 2C and 2CMH built between 1989 and 2016.
Constructed from high‑grade marine‑grade rubber compound, this impeller delivers excellent elasticity, tear‑resistance and salt‑water corrosion resistance. It maintains stable blade performance under continuous rotating work. Following regular service intervals can effectively prevent blade cracking, surface scuffing and premature wear caused by harsh marine operating environments.
Every structural dimension and inner‑bore specification strictly follows OEM standards, enabling quick, precise and hassle‑free drop‑in fitting. This aftermarket component resolves common cooling‑system faults such as engine overheating, insufficient cooling‑water output, weak water circulation and worn‑out impeller blades.
Swap your aged or damaged impeller with this unit to restore stable cooling‑water circulation for your Yamaha outboard motor. Always apply dedicated water‑pump lubricant during assembly and never run the engine without water supply. Correct fitting guarantees long‑term reliable cooling performance under practical marine working scenarios.
