Checking to see if anyone would know why this fuse would burn like this? This was the correct fuse (20 amp fuse) and no other fuses were affected.

Serial number: 1A649056

Boat would crank, crank, and crank, but never turn over. Got it to turn over one time on the lake 2 weeks ago, but when I pulled it out of the water, I put it in storage, and then took it to the welding shop to get one of the toons welded as I had a hairline crack that needed welded. Come back this weekend to take it out, and batteries were showing 12.4 volts, went to crank it and kept cranking like before.. Finally thought it was a starter or maybe a clogged fuel filter as it acted like it was getting no spark. Happened to think about checking the fuses and found this one completely burnt.

With nothing other than the picture to go on, I'd say it burnt up because it got too hot....as to why, lots of potential contributors.
