Monofilament Line in the Motor- ruining lower unit

[BeastMan]

Picked some up in my trolling motor in Leeville while fishing a cpl years ago. Looked down and there was a birds nest on green mono dragging behind it. No green mono in our boat. Figured a big red, jack, or shark spooled somebody and we were just unlucky to find it. Obviously trolling motor is easier to deal with but same thing.
