I have a 1978 Johnson 70HP that has given me some problems the last 2 times out. The first time I took it out it started the day great and then after hitting a couple fishing holes I tried to start my engine and nothing happend. It was like the electrical wasn't grounded. So my brother and I followed the wires from the ignition to the motor and jiggeled them a little, checked for possible loose connections and found a couple possible culprits. We then tried to restart it and nothing. well we continued to do the same thing over and over and it eventually started. So we went to our next fishing hole, turned the engine off and when we restarted it it cranked right up, then later in the day when we stoped and then tried to start it up and it wouldn't start again, until about 10 minutes of playing with wires. We then headed in. I'm not even sure if the playing with wires did anything. It just seemed to work when it wanted. This past week We replaced some of the old wires going from the ignition. and Cleaned off all terminals. Yesterday we took the boat out all day and when we hit our last stop on the way in it decided not to start again. The same Thing. When you try and turn the key over nothing happens at all. This time we wern't so lucky to get it going again and we had to be towed in. Anyy ideas on what the problem could be? I'm clueless and have no idea where to start. Any help would be greately appreciated!
