Independent Product Description
This heavy‑duty marine water pump impeller is a reliable aftermarket replacement designed for Yamaha 4‑stroke 9.9HP outboard models F9.9 and T9.9, production years 1991‑1997.
Constructed from high‑grade marine‑grade rubber compound, this impeller provides excellent elasticity, superior tear‑resistance and solid salt‑water anti‑corrosion performance. It maintains stable blade geometry under continuous rotating load. Regular service intervals effectively prevent blade cracking, scuffing and premature wear under harsh marine boating environments.
Every physical dimension and inner‑bore specification strictly meets OEM standards, enabling quick, accurate and hassle‑free drop‑in fitting. This replacement resolves common cooling‑system faults such as engine overheating, insufficient cooling‑water flow, weak water discharge and heavily worn‑out impeller blades.
Swap your worn‑out or damaged impeller with this unit to restore stable cooling‑water circulation for your Yamaha outboard motor. Apply dedicated water‑pump lubricant during assembly and never run the motor without water supply. Correct fitting guarantees long‑term dependable cooling performance under real‑world marine working scenarios.
