I have a 1986 bayliner with a Force 125 outboard. Yesterday I had the family out. Boat started fine the first time. We went and sat in a cove and got stranded. Boat wouldnt start. I noticed a black wire that is hooked to the ignition..it is hot(positive). the other end of the wire is loose. I have no idea where it hooked to on the other end. I ended up touching it to the positive going into my car lighter. That allowed me to start the boat. I know that is not right, but it got me off the lake. Speedometer stopped working also and depthfinder is acting crazy now too. I dont know if it is all related but it all started at the same time. the boat was fine the day before.... PLEASE HELP. Thank you
