This heavy‑duty aftermarket water pump impeller is a trusted replacement for NISSAN 2‑stroke 6‑9.8HP outboard motors including M6B, M8B and 9.8B. Constructed from marine‑grade neoprene rubber, it offers excellent tear‑resistance, anti‑aging property and good salt‑water anti‑corrosion capability for tough offshore and inland marine environments.
Under sustained rotating load, the impeller keeps consistent blade geometry and reduces chances of blade cracking, surface abrasion and permanent deformation. All key dimensions follow OEM requirements, supporting fast and straightforward drop‑in installation. It solves frequent cooling‑system failures such as engine overheating, low cooling‑water flow and poor water discharge triggered by worn original impellers.
Replace your worn or damaged impeller to regain stable cooling‑water circulation for your NISSAN outboard. Use proper water‑pump lubricant while installing. Avoid running the engine without water source, which helps prolong impeller service life and maintains dependable engine output during on‑water operation.
