Are the hydraulic rams underwater?
Absolutely not! The reason you lift your boat out of the water in the first place is to protect it from the destructive nature of the harsh saltwater conditions. To place your boatlift in the same condition youre trying to keep your boat out just doesnt make sense. In addition, the hydraulic ram is only exposed when the lift is lowered. It is safely retracted into the cylinder when the boat is in the raised position and housed in a protective aluminum housing. No matter what someone tells you, if you place anything in the water for long, the water will always win!
