1983 Yamaha Outboard

Tonight I was cranking my outboard when I noticed the positive wire was melting. Any ideas what would cause this? It's a 1983, 25hp electric start.

The whole wire? The end on the battery? The end on the starter motor?

I know barely anything about those motors but Iíll guess that one end was hot and that itís a corroded connection to the lug on that end.

Re: 1983 Yamaha Outboard

Could be loose lug, corroded terminal, wires corroded etc etc. Or may be starter itself needs new brushes or build up of carbon is reducing electric motors ability to crank efficiently, but at that age I would start with new wires + and - from battery to starter and install a fuse or breaker.
