This robust aftermarket water pump impeller is a reliable drop‑in replacement compatible with Tohatsu OEM 309‑65021‑1, Mercury part 47‑114812, alongside aftermarket cross‑reference numbers CEF 500396, Mallory 9‑45312 and Sierra 18‑8914.
Built using premium marine‑grade neoprene rubber, this impeller delivers great tear‑resistance, dependable anti‑aging performance and solid salt‑water corrosion resistance. It maintains stable water pumping output under tough marine working conditions.
Under continuous rotating load, the impeller retains its original blade profile. It effectively reduces common failures such as blade cracking, surface scuffing and permanent structural distortion caused by long‑time seawater operation.
All critical dimensions strictly follow OEM specifications. Installers can finish fast, hassle‑free drop‑in installation with no trimming or modification required. This replacement resolves typical cooling‑system malfunctions including engine overheating, insufficient cooling‑water flow and weak water discharge, which are mostly caused by worn‑out original impellers.
Swap your aged or damaged impeller for this unit to restore stable cooling‑water circulation for your outboard engine. Apply proper water‑pump lubricant during assembly work. Never start the motor without adequate water supply. Follow standard marine service guidelines to extend impeller service life and keep consistent engine performance on the water.
