Boat won't start. Please help.

[Lee18]

I was hoping someone can help me. My 2013 AR190 won’t start. The battery tested fine at 800 CCA. What I get when a turn the key is one clunk sound and that’s it except for a low grade hum and the loud alarm saying check engine. I am not positive I have the battery connected correctly. Forgot to mark the connections when I took the battery out for the season. There are five wires. I know the main positive and main negative but the other three I’m not so sure about. I think there are three wires connected to the negative and to connected to the positive. One wire has a Fuse attached to it. I had the fuse wire and standard positive cable attached to the positive and the standard negative cable plus tow others attached to negative. I think that's correct but not sure. Any other help or suggestions would be much appreciated. And one more thing, my battery terminals heated up so much that I burned my finger trying to disconnect the positive cable. This may not have anything to do with the battery but that's the place I started.

All the connections are tight and the terminals are clean. Doesn’t mean I Connected them correctly though.
