Won’t start, need help

[Grafto4408]

I was at the landing and put boat in water. Hopped in and lower motor then tried starting. Turned over once and then dead. I think it’s a fuse but can’t find the problem. 2003 40 hp TLRNC. Have power and batteries charged. In neutral and check killed switch. All fuses I found are good. Only found one in the motor and don’t know if there are others. Power trim isn’t working and engine won’t turn over

sounds like a bad battery or battery connection

After starting from the beginning, I took all the connections off the battery and found corrosion on the wires. Cleaned up and worked perfectly. I feel pretty dumb but at least I didn’t pay money to a mechanic. Lol
