This tough marine water pump impeller acts as a reliable aftermarket replacement with OE number F8‑04000200, compatible with 8‑9.8HP outboard boat motors from Tohatsu, Nissan, Mercury and Mercruiser.
It is molded from high‑quality marine‑grade rubber compound. The impeller holds good flexibility, solid tear‑resistant traits and dependable anti‑corrosion ability against salt‑water. It maintains steady blade shape under continuous rotary loads. Timely component swap helps prevent blade cracking, surface scuffing and early‑stage wear in harsh salt‑water boating environments.
All dimensional parameters and inner‑bore tolerances match OEM requirements precisely. Users can carry out quick, accurate drop‑in fitting without extra adjustments. This replacement resolves frequent cooling‑system issues: engine overheating, insufficient cooling‑water flow, weak water output and heavily worn‑out impeller blades.
If your original impeller is worn or cracked, install this part to recover stable cooling‑water circulation for your outboard motor. Apply professional water‑pump lubricant during assembly. Never start the motor without water supply. Correct fitting delivers consistent, long‑term cooling performance for real‑world marine operating conditions.
