1987 mercury 115 bogs after full throttle

[waterguy123]

I had the grey lines never thought it would do this I think there original my grandpa barely used it before I got it 5 years. Do these things not get much wear bc how they are built I still have cross hatching on all cylinders

The crosshatching remains well after there has been some wear.------If this motor is still using the " autoblend " mixer unit then remove it and throw it away.-----Run with a 50 :1 mix or 45:1 if it is working hard.--Such as tubing / waterskiing.
