Installing a fuse or circuit breaker is essential to prevent damage to your trolling motor if it becomes stressed or overheated. By doing so, you can avoid costly repairs or replacements down the road. This will help keep your motor running smoothly and prevent any unexpected shutdowns. It is typically used in conjunction with a fishing boat, allowing the boat to be moved without using a paddle or oar. A trolling motor typically does not need a fuse, as it is not connected to the boat’s electrical system.
