Independent Product Description
This heavy‑duty marine water pump impeller is a dependable aftermarket replacement designed for Yamaha 4‑stroke 9.9HP outboard engines produced from 1998 to 2005.
Constructed from high‑grade marine‑grade rubber compound, this impeller delivers excellent elasticity, outstanding tear‑resistance and reliable salt‑water anti‑corrosion performance.
It keeps stable blade geometry under continuous rotating load. Regular service intervals help avoid blade cracking, scuffing and premature wear under harsh marine operating conditions.
Every structural dimension and inner‑bore specification strictly meets OEM standards, enabling quick, accurate and hassle‑free drop‑in fitting. This replacement resolves typical cooling‑system faults such as engine overheating, insufficient cooling‑water flow, weak water discharge and worn‑out impeller blades.
Replace your aged 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 reliable cooling performance under real‑world marine working scenarios.
