This robust aftermarket water pump impeller is a direct replacement for Nissan 2.5HP and 3.5HP two‑stroke outboard motors. It matches OEM part numbers 309‑65021‑1M and 309‑65021‑1, also works with equivalent cross‑reference part codes including Mercury 47‑114812, Sierra 18‑8914, Mallory 9‑45312 and CEF 500396.
Built using premium marine‑grade neoprene rubber, this impeller offers outstanding tear‑resistance, reliable anti‑aging performance and great salt‑water corrosion resistance. It maintains consistent water‑pumping performance under harsh marine working environments.
Under sustained rotating load, the impeller holds its original blade profile. It effectively reduces common failures such as blade cracking, surface scuffing and permanent structural distortion caused by long‑term seawater operation.
All critical dimensions strictly follow OEM specifications. Installers can complete fast, hassle‑free drop‑in installation without trimming or extra modification. This replacement resolves typical cooling‑system malfunctions such as engine overheating, insufficient cooling‑water flow and weak water discharge, which are mainly triggered by worn‑out original impellers.
Swap your worn or damaged impeller for this unit to restore stable cooling‑water circulation for your Nissan outboard. Apply proper water‑pump lubricant during assembly work. Never start the engine without adequate water supply. Follow standard marine service guidelines to extend impeller service life and keep dependable engine performance on the water.
