Independent Product Description
This robust rubber water pump impeller is a reliable aftermarket replacement compatible with OEM part numbers 646‑44352‑00 and 646‑44352‑01 for Yamaha outboard motors.
Made of high‑performance marine‑grade rubber compound, this impeller provides good elasticity, strong tear‑resistance and excellent salt‑water corrosion resistance. It maintains stable blade geometry under continuous rotating loads. Regular service intervals effectively prevent blade cracking, scuffing and premature failure under harsh marine operating conditions.
All structural dimensions and inner‑bore specifications strictly match OEM standards, supporting fast, accurate and trouble‑free drop‑in installation. This replacement solves common cooling‑system issues including engine overheating, insufficient cooling‑water flow, weak water output 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. Proper fitting guarantees long‑term dependable cooling performance under real‑world boating scenarios.
