Mercury Marine water pump impeller 47-89983T is a genuine OEM impeller for the cooling water pump on selected Mercury and Mariner outboard motors. The impeller features six flexible vanes as well as a metal hub with a keyway for power transmission.
The impeller measures 51.8 mm in outer diameter, 19.3 mm in inner diameter, and 19 mm in height. It is used as a replacement part in the engine's cooling water pump.
The part fits documented Mercury and Mariner applications from 30 to 70 hp, including selected 2-cylinder, 3-cylinder, and 4-cylinder 2-stroke engines. For many models, compatibility depends on the year of manufacture, country of production, and serial number, which should therefore be checked before ordering.
Spare part number 47-89983T replaces the previous OEM numbers 47-20268, 47-65959, 47-89983, and 47-89983B. This product is the individual impeller and should not be confused with the repair kits 47-89983T1 or 47-89983Q1.
