1998 125 Merc, Serial# OG663892. I installed a water pressure gauge on the motor today, took it to the river to run it to see if there were any leaks. When I was loading up I noticed water dripping out of the front of the cowl. Got home and hooked it up to the hose and water is spraying from out around the top spark plug. I pulled the plug and there was no water on the electrode. I cannot see any cracks any where on the head or around the plug hole. The water seems to be coming out of the bottom of the plug hole back in the spark plug recess. Any clue about what's going on?
