I want to either get a kit to rebuild the water pump or just by the entire assembly, but im not sure which water pump/kit that i will need for a 1997 mercury 25 hp 2 stroke.Serial Number 0G474648,1997 year,model is 25el according to transom plate.Any help will be greatly appreciated.Thanks in advance.
Well to start of, and two, A 25 hp does not have a water pump, like a car, it has am impeller driven by the out board motors gear system
Water pump rebuild kit from Mercury, part# 99157T2, about $65. The kit includes the impeller, all gaskets and seals, wear plate and pump body insert. Sierra marine offers a cheaper kit, but their kit does not include the wear plate or pump insert, and these parts cannot be purchased separately from Sierra, so I would not recommend this kit, unless your wear plate and pump insert have been previously changed in the last 3 years.
