This robust aftermarket water pump impeller is an essential component for Tohatsu and Nissan 2.5‑3.5HP two‑stroke outboard water pump repair assembly. It is directly interchangeable with OEM part numbers 309‑65021‑1 and 309‑65021‑1M, and matches cross‑reference codes including Mercury 47‑114812, Sierra 18‑8914, Mallory 9‑45312 and CEF 500396.
Built using premium marine‑grade neoprene rubber, this impeller features outstanding tear‑resistance, long‑term anti‑aging performance and reliable salt‑water corrosion resistance. It delivers steady water‑pumping performance even under tough salt‑water boating conditions.
Under continuous rotating load, the impeller maintains its original blade profile. It effectively reduces common failure modes such as blade cracking, surface scuffing and permanent structural distortion after long‑time marine service.
All physical dimensions and bore size strictly conform to OEM specifications. It supports quick and accurate drop‑in installation with no trimming or modification needed. This replacement fixes typical cooling‑system issues: engine overheating, insufficient cooling‑water flow and weak water discharge, which are mostly caused by worn original impellers.
Swap your aged or damaged impeller for this unit to restore proper cooling‑water circulation during water pump repair work. Apply recommended water‑pump lubricant before installation. Never start the outboard without adequate water supply. Follow standard marine service procedures to extend impeller service life and keep stable engine performance on the water.
