This robust aftermarket water pump impeller serves as a reliable replacement for Tohatsu 6‑8‑9.8HP outboard engines with OE reference 3B2‑65021‑1. Made of high‑quality marine‑grade neoprene rubber, it delivers solid tear‑resistance, anti‑aging performance and reliable salt‑water anti‑corrosion for harsh marine conditions.
It retains proper blade shape under continuous rotational stress, lowering risks of blade cracking, scuffing and permanent deformation. All critical dimensions follow OEM specs for quick, tool‑friendly drop‑in installation. This part fixes typical cooling‑system faults including engine overheating, insufficient cooling‑water flow and weak water output caused by worn‑out factory impellers.
Install this new impeller to restore consistent cooling‑water circulation for your Tohatsu outboard. Always apply water‑pump lubricant during assembly. Never operate the motor without water supply, which extends impeller service life and keeps stable engine performance while on the water.
