While the hydraulic lift tubes are installed above the water, they can be flooded out without issue. The only portion of the lift that shouldn't get wet is the motor and batteries. All of our systems are designed with quick disconnects to easily and quickly remove the motor and batteries in the case of rising waters. If you get flooding regularly, we can install the hydraulic box above the dock on a bench, shelf, or in the rafters so you don't have to worry!
