I was running the boat one day and after stopping at an island for a quick people drop of and when I went to start it again it didn't want to crank after a couple of turns of the key it finally started to crank with a turn over and running. Then later that day when it was time to leave I turned the key and all i could hear was a click like the starter solenoid was engaging.. I finally was able to start it with a screw driver jumping the starter solenoid. I replaced the starter solenoid thinking it was bad but nothing. Still the same one click when I turn the key. Help!! Any ideas?
