Well, half way through the turn my thruster quit.

Later when I checked the thruster (24V with two 8D batteries in bow), the cable clamp had melted off the battery terminal! At those amps a little resistance is all it takes to generate a lot of heat.
Honestly that sounds more like it wasn't fused or wasn't properly fused. That is really the purpose of the fuse and why best practices have you fuse as close to the battery as possible. Draw passed through a fuse and allowed cables and connectors to melt?

That really sounds like an improperly fused circuit IMHO.
