"I have a similar problem with my 1989 Yamaha 115. The water has three places it can be coming from; exhaust cover gasket, cylinder head gasket or power head mounting gasket. There could also be bad corrosion in these areas causing the problem as well. My motor is at the third phase of these likely places and I am having problems with seized and broken bolts in the powerhead, not fun! Still keeping my fingers crossed."
