This robust aftermarket water pump impeller serves as a reliable drop‑in replacement for Nissan and Tohatsu 2.5HP and 3.5HP two‑stroke outboard motors including M2.5A, NS2.5A, M3.5A and NS3.5A. It is interchangeable with OEM part number 309‑65021‑1, 309‑65021‑1M and matches equivalent cross‑reference part codes such as Mercury 47‑114812, Sierra 18‑8914, Mallory 9‑45312 and CEF 500396.
Built using premium marine‑grade neoprene rubber, this impeller delivers excellent tear‑resistance, dependable anti‑aging performance and solid salt‑water corrosion resistance. It keeps stable pumping performance under harsh marine operating environments.
Under continuous rotating load, the impeller retains its original blade profile. It effectively minimizes common failures including blade cracking, surface scuffing and permanent structural distortion caused by long‑term seawater service.
All key dimensions comply with OEM specifications strictly. Installers can complete fast, hassle‑free drop‑in fitting without extra trimming or modification. This replacement fixes typical cooling‑system malfunctions such as engine overheating, insufficient cooling‑water flow and weak water discharge, which are mainly caused by worn‑out factory impellers.
Replace your aged or damaged impeller with this unit to restore proper cooling‑water circulation for your Nissan or Tohatsu outboard. Apply recommended water‑pump lubricant during assembly work. Never start the engine without sufficient water supply. Follow standard marine maintenance guidelines to extend impeller service life and sustain consistent engine performance on the water
