Raw Sea Water Pump MerCruiser TR2 TRS 1972-1976 with a brass body pully and bracket.
Removed from a Mercruiser 225 2TR (302 Ford)
If you have a TR2 or TRS drive this would make a great spare on board. Replace the rubber impeller before use. Removed from a working system. These pumps are heavy-duty, and almost last forever. Mounting bracket is on the pump and included in the sale. See pictures.
