This robust aftermarket water pump impeller acts as a direct replacement for Tohatsu and Nissan 2.5‑3.5HP two‑stroke outboard engines. It is fully interchangeable with OEM part numbers 309‑65021‑1 and 309‑65021‑1M, and compatible with cross‑reference part numbers including Mercury 47‑114812, Sierra 18‑8914, Mallory 9‑45312 and CEF 500396.
Built using high‑grade marine‑grade neoprene rubber, this impeller delivers great tear‑resistance, reliable anti‑aging property and excellent salt‑water corrosion resistance. It maintains steady water‑pumping performance under demanding salt‑water marine environments.
Under continuous rotating load, the impeller keeps its original blade geometry. It effectively lowers common failure risks such as blade cracking, surface scuffing and permanent structural distortion caused by long‑time seawater service.
All physical dimensions and inner‑bore specifications strictly match OEM standards. Installers can finish quick, hassle‑free drop‑in fitting without trimming or modification. This replacement fixes typical cooling‑system troubles: engine overheating, insufficient cooling‑water flow and weak water discharge, which are mostly caused by worn‑out factory impellers.
Replace your aged or broken impeller with this unit to restore stable cooling‑water circulation for your Tohatsu or Nissan outboard. Apply suitable water‑pump lubricant during assembly work. Never start the engine without sufficient water supply. Follow standard marine maintenance practices to extend impeller service life and keep consistent engine performance on the water.
