hello everyone, I recently invested in my first boat. It's a 15ft spitfire with a 90 horsepower Johnson seahorse. I'm not sure of the exact year but I think it's somewhere in the early 80s. When I got the boat all the cables from the motor where disconnected which is fine because I knew how to hook the steering cable and throttle cables up. My only problem is I can't find out where to hook the battery up to the motor at. this may be a stupid question but it's my first boat so I'm still learning as I go along. If anyone can help me it would be greatly appreciated.
