This heavy‑duty aftermarket water pump impeller acts as a reliable drop‑in replacement for Tohatsu 9.9‑20HP two‑stroke and four‑stroke outboard motors. It is fully interchangeable with OEM part number 334‑65021‑0M and related cross‑reference part numbers, also compatible with aftermarket references Sierra 18‑8904 and CEF 500336.
Molded from high‑grade marine‑grade neoprene rubber, this component offers excellent tear strength, trustworthy aging resistance and strong salt‑water corrosion resistance. It delivers consistent performance under harsh marine operating environments.
Under continuous rotating load, the impeller preserves its original blade profile. It effectively minimizes common failures including blade cracking, surface scuffing and permanent structural distortion.
All critical dimensions follow OEM specifications. This enables installers to complete fast, hassle‑free drop‑in installation without extra adjustments. This replacement fixes typical cooling‑system malfunctions such as engine overheating, inadequate cooling‑water flow and weak water output, which are mainly caused by worn‑out factory impellers.
Replace your worn or damaged impeller with this unit to restore stable cooling‑water circulation for your Tohatsu outboard. Apply designated water‑pump lubricant during assembly work. Never start the engine without sufficient water supply. Follow these practical operating tips to extend impeller service life and maintain stable engine performance during marine trips.
