I tried starting my boat today

I tried starting my boat today and it turned over for about 10 seconds but didn’t start. I tried again and eventually wore my battery down. Now with a fresh charge on the battery it wont turn over it just grunts. Did I blow a fuse or overheat something. And I noticed the negative on the battery cables is very hot after cranking. Any help would be appreciated. Thanks

You need to remove and get you

You need to remove and get your starter rebuilt (or buy a replacement--70 bucks on eBay).
