I have a 125hp 1999 mariner that is leaking water out of the top plug. I picked up a replacemnet gasket, but when i replace it do I need to worry about torquing the bolts to a certain specification?
I have a 1999 mariner 125hp that is leaking water out of the top spark plug. Is this serious or is it just a gasket? Can it cause any major damage or should i get it fixed immediately? Can i do it myself? Also i cant seem to find the serial number anywhere on the motor? Thanks in advance.
