This robust aftermarket water pump impeller serves as a reliable drop‑in replacement for Mercury and Mariner small‑horsepower outboard motors. It is compatible with 1‑cylinder and 2‑cylinder engines ranging from 2HP up to 6HP. It matches OEM part numbers 47‑16154‑3 and 161543, alongside cross‑reference codes Sierra 18‑3048, Mallory 9‑45603, GLM 89840 and CEF 500322.
Built using premium marine‑grade neoprene rubber, this impeller delivers excellent tear‑resistance, dependable 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 keeps 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 resolves 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 aged or damaged impeller for this unit to restore stable cooling‑water circulation for your 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.
