Re: engine lugs down at full throttle
Sounds like a classic case of fuel pump flooding.<br />Seems to happen alot, especially with 10-15 year old Force motors. Seems they didn't hold up to the new fuels on the market today.<br /><br />Basicly the seals, springs, and diaphram in the fuel pump get old and develope leaks. All is fine when you first run the cold engine.<br />When you turn it off for a while, the fuel leaks thru the pump, into the powerhead, creating a severely flooded condition ( possibly fouling the plug) in the lower cylinder when you turn the motor over.<br /><br />The good news is that the rebuild kit is less than $15 at any Mercury dealer, and you can do it yourself in about 30 minutes.<br />The kit comes with directions. <br /><br />This should probably be done anyway, on a motor of that age.<br /><br />I hope this solves the problem.
