This sturdy aftermarket water pump impeller is a trustworthy replacement for Yamaha 20‑25‑30HP two‑stroke outboard motors covering models 20C, 25C and 30A. Made from premium marine‑grade neoprene rubber, it provides great tear‑resistance, anti‑aging property and solid salt‑water anti‑corrosion performance under tough marine operating conditions.
It maintains stable blade geometry under continuous spinning load, reducing risks of blade cracking, surface scuffing and permanent deformation. All key dimensions comply with OEM specifications to enable fast and simple drop‑in installation. This replacement resolves typical cooling‑system troubles such as engine overheating, insufficient cooling‑water flow and weak water discharge brought on by worn‑out original impellers.
Swap out your aged or broken impeller to bring back reliable cooling‑water circulation for your Yamaha outboard. Remember to apply dedicated water‑pump lubricant during fitting. Never run the engine without water supply, which extends impeller service life and keeps consistent engine output during on‑water operation.
