Yamaha 6GR-12451-00-00 Water Pump Impeller
The water pump impeller part number 6GR-12451-00-00 is a flexible rubber rotor that draws cooling water through the lower unit and pushes it up into the engine to absorb excess heat. Over time the blades wear, harden or break, reducing flow and causing the engine to run hot. Yamaha recommends replacing the impeller every 100 hours of operation or once per season. A failing impeller can cause symptoms such as an overheating alarm, a weak tell?tale stream or rubber debris in the pump housing. This genuine Yamaha impeller is engineered to meet factory specifications and will restore the cooling system’s performance when installed. Replacing the impeller as part of regular maintenance helps protect your outboard from overheating and costly damage.
Flexible rubber blades draw and circulate cooling water through the outboard. OEM Yamaha impeller ensures proper fit and restores cooling system performance.
The 6GR-12451-00-00 water pump impeller is compatible with the following Yamaha outboard models:
Yamaha F425
Yamaha FL425
Yamaha F375
Yamaha F375A
