This robust aftermarket water pump impeller is a reliable drop‑in replacement for Nissan two‑stroke marine outboard motors. It works for NS9.9, NS15 and NS18 two‑stroke outboard engines. It matches OEM part number 334‑65021‑0 and compatible variants 334650210, 334650210M, together with aftermarket cross‑reference Sierra 18‑8921.
Built using premium marine‑grade neoprene rubber, this impeller delivers outstanding tear‑resistance, dependable anti‑aging performance and strong salt‑water corrosion resistance. It maintains stable water‑pumping performance under harsh salt‑water marine operating environments.
Under sustained rotating load, the impeller retains its original blade profile. It effectively minimizes common failure modes 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 resolves typical cooling‑system malfunctions including engine overheating, insufficient cooling‑water flow and weak water discharge, which are mostly triggered by worn‑out original impellers.
Swap your worn or damaged impeller for this unit to restore stable cooling‑water circulation for your Nissan outboard. Apply recommended water‑pump lubricant during assembly work. 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.
