This robust aftermarket water pump impeller is a dependable service replacement for Nissan and Tohatsu small‑horsepower outboard motors. It covers 2HP, 2.5HP, 3.5HP, 4HP, 5HP and 6HP two‑stroke and four‑stroke outboard engines. It matches OEM part numbers 369‑65021‑1 and 369650211, together with part variant 369‑65021‑0 and aftermarket cross‑references Sierra 18‑8912, Mallory 9‑45402 and CEF 500346.
Built using premium marine‑grade neoprene rubber, this impeller delivers excellent tear‑resistance, reliable anti‑aging performance and strong salt‑water corrosion resistance. It maintains stable water‑pumping output under harsh marine operating environments.
Under sustained rotating load, the impeller preserves its original blade geometry. It effectively minimizes common failures such as blade cracking, surface scuffing and permanent structural distortion caused by long‑term seawater service.
All critical dimensions strictly comply with OEM specifications. Installers can complete fast, hassle‑free drop‑in fitting without trimming or extra modification. This replacement fixes typical cooling‑system malfunctions: 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 / Tohatsu outboard. Apply proper water‑pump lubricant before installation. Never start the outboard motor without adequate water supply. Follow standard marine maintenance guidelines to extend impeller service life and keep dependable engine performance on the water.
