This heavy‑duty aftermarket water pump impeller is a dependable replacement for Mercury and Mariner two‑stroke outboards, specifically for 25HP 25C through‑propeller‑exhaust model and 28HP unit with Mode Code 664. Built with premium marine‑grade neoprene rubber, it delivers excellent tear‑resistance, anti‑aging characteristics and strong salt‑water anti‑corrosion performance in harsh marine environments.
It holds consistent blade shape under constant rotational load, minimizing blade cracking, abrasion and permanent deformation. Every critical dimension matches OEM specs for quick and straightforward drop‑in installation. This component fixes common cooling‑system issues including engine overheating, low cooling‑water flow and poor water output caused by worn factory impellers.
Replace your old or damaged impeller to restore stable cooling‑water circulation for your Mercury‑Mariner outboard. Always use water‑pump lubricant during fitting. Avoid running the motor without water supply, which helps extend impeller service life and ensures steady engine performance while out on the water.
