need help with a 125 hp mariner

[subman77]

I just bought a used 125 mariner and when we fired it up it was leaking water out of the top spark plug. Does anyone know what might be wrong. The motor runs fine I think the gasket is shot but not sure.

check out iboats forum on mariner motors; you should be able to find everything you need there.
