It tends to blow up the voltage regulator. Other parts can be damaged. Hopefully you will fix the battery cable.

If you're using wing nuts, throw em as far as you can and replace with ss hex nuts and washers, tightened with a wrench.

Not in my boat, but in my Maverick, I had the battery in the trunk and not secured securely...Anyways, took a turn with the wheels spinning, my battery rolled over and disconnected the cables, so running on my alternator now. Was about a mile, mile and a half from home, so headed that way. Burned out my tachometer, air/fuel ratio gauge, a couple other things. Cost me WAY more to fix it than it would have to secure the battery...
