I have a 1980 chrysler 45 hp outboard. I went fishing yesterday and when I put the boat in the water the motor started right up with no problems. I fished for a couple of hours then went to start the motor and nothing, there was no power at all. I turned the key and the motor didn't try to turn over at all, not even a clicking noise or anything. The battery had plenty of charge, the motor was in neutral, and checked the battery connections and they were all tight. Was wondering if anybody had any ideas for me? Thanks
