I have a 1991 Force 90hp with trouble. The motor starts up just fine when cold and runs great. When the motor is warm it is difficult to start and when you shift into gear it is hard to keep it from stalling. When you put it in neutral and try to give it some gas it seems sluggish and does not gain much RPM. Sometimes I have to put it in neutral and give it some rpms then quickly put it into gear in order for it to run. Once running probably 5mph its great. Any suggestions would be thankful. I found an electrical box, 1.5? x 2.25? with three connections, 1 yellow wire, 1 red wire and 1 yellow & grey wires, it also has what looks like a ground. The ground appears to have been arching and is broken. What is this and could it be the problem?
