I just bought a Minn Kota Endura 30lbs thrust trolling motor to push my 14.2 in and out of the little cove I sail out of on Lake Grapevine in Texas. The instructions say that I MUST install a fuse or circuit breaker...but has no direction. Anyone have experience with this? Will this thing electrocute me if I capsize without a fuse? Also...anyone else using a 30lbs Minn Kota have an opinion about the power/performance vs. as a 45lbs?
