This durable marine water pump impeller serves as a solid aftermarket replacement with OE reference 3B2‑65021‑1, built for NISSAN NS8, NS9.8 two‑stroke and NSF8, NSF9.8 four‑stroke outboard boat motors.
Made of premium marine‑grade rubber compound, this impeller delivers nice flexibility, strong tear‑resistant performance and reliable salt‑water corrosion resistance. It keeps stable blade shape under ongoing rotary loads. Timely part replacement helps avoid blade cracking, surface scuffing and early‑stage wear in tough salt‑water boating environments.
Every dimensional parameter and inner‑bore tolerance align closely with OEM standards. Operators can complete fast, accurate drop‑in fitting with no further adjustments. This replacement fixes common cooling‑system troubles including engine overheating, inadequate cooling‑water flow, weak water discharge and heavily worn‑out impeller blades.
Swap your worn or broken impeller with this component to restore smooth cooling‑water circulation for your NISSAN outboard motor. Apply dedicated water‑pump lubricant during assembly. Never run the motor without water supply. Proper fitting brings steady, long‑lasting cooling performance for practical marine working scenarios.
