This rugged aftermarket water pump guide plate is a practical spare part built for Tohatsu 80HP and 90HP marine outboard motors. It works as an interchange component matching OEM part numbers 3B7‑65025‑0 and 3B7‑65239‑1.
Made from heavy‑gauge anti‑corrosion steel, this backing plate keeps excellent flatness on its working face. It offers solid wear‑resistance and stable structural performance to handle long‑term marine cooling‑system operation.
It installs inside the water pump housing to back the water pump impeller. It maintains proper running clearance for impeller blades and supports stable cooling‑water circulation when the outboard runs under typical boating workloads.
Manufactured in strict compliance with original OEM specifications, this plate reduces impeller friction and slows down premature part wear. It fixes frequent cooling‑system issues such as weak water output, fast impeller damage and engine overheating. These troubles usually appear when original guide plates get bent, grooved or corroded over service time.
All key dimensions align with OEM standards. Users can finish quick drop‑in installation without trimming or extra adjustments.
Thoroughly wash away sand and debris from the pump housing prior to fitting.
Take care not to scratch or warp the plate surface during assembly work.
Swap your worn, warped or pitted factory water pump guide plate with this aftermarket spare. You will bring back steady water‑pump function for your Tohatsu outboard. Stick to regular marine maintenance routines. These practical measures extend cooling‑system service life and maintain trustworthy engine performance while operating on the water.
