The Boat Lift Buddy Wheel Drive System is designed for boat lift owners looking for an economical complete one-box system with quick installation and reliable service. Boat Lift Buddy installs in minutes with a universal design that fits virtually all lifts with a manual wheel. Installation requires only common hand tools. This 12-volt system is designed for lifts without access to shore power, coming equipped with a 15' cable and quick disconnect plug to run off your boat's battery. Each unit is tested three times before packaging. Whether you're on the lake or the river, Boat Lift Buddy is your friend on the water. Not recommended for a run of more than 100' between the Boat Lift Boss and the power source.
