This robust aftermarket water pump impeller serves as a reliable drop‑in replacement for Nissan and Tohatsu 3.5HP two‑stroke outboard motors including M3.5A, M3.5B, M3.5B2 and NS3.5B2 of corresponding production years. It matches OEM part 369‑65021‑00 and aftermarket cross‑reference numbers Sierra 18‑8902 and CEF 500328.
Built using premium marine‑grade neoprene rubber, this component offers good tear‑resistance, dependable anti‑aging performance and solid salt‑water corrosion resistance. It delivers stable pumping performance under harsh marine operating environments.
Under continuous rotating load, the impeller keeps its original blade profile. It effectively minimizes common failures such as blade cracking, surface scuffing and permanent structural distortion.
All key dimensions comply with OEM specifications. Installers can complete fast, hassle‑free drop‑in fitting without further modification. This replacement fixes typical cooling‑system malfunctions: 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 keep consistent engine performance on the water.
