ABSTRACT:
A lift is placeable in a waterbody for a watercraft having a water intake port and a water drawing device for drawing water through the water intake port. The lift includes a tank. The tank has an interior and an exterior, with the interior including a chamber. The tank also has an upper surface configured for receiving the watercraft, and a water inflow port and a selectively actuable valve for permitting water to flow into the chamber. A water outflow port is provided which is configured to be matable with the water intake port. The water intake port of the watercraft can be mated with the water outflow port of the tank to permit the water drawing device of the watercraft to draw water out of the tank.
