Bought a used pontoon with mercury classic 50 on it. Boat sat since last summer. Put muffs on it turned key started on 2nd try. Ran great throttle response was great. Next day took it to water. Wouldn't gof over half throttle.decided to rebuild carbs and clean. After bolting things back up I noticed I put the small ground wire that was supposed to bolt to starter ground on the positive starter post. Needless to say almost had a fire and wire burned into. I didn't replace wire as it just burned that wire which I'm figuring is a ground feed wire to rectifier and starter solenoid. Anyway when I tried to start it again today I noticed more smoke. Upon inspection I noticed there are 2 naked ground straps on the back of the motor. One is burnt into and the other is crusty feeling. Could me not rewiring the ground cause the two ground straps to burn like that? The motor would just click and not even attempt to start. Tried starting 4 or 5 times then the clicking quit.
