A self-leveling hydraulic motor driven boat lift includes proximal and distal support structures disposed on respective longitudinal sides of a lift platform. A pair of proximal and distal hydraulic motors are operably mounted to the proximal and distal support structures respectively. Each hydraulic motor is operably connected to a respective winder mechanism. A lift cable assembly is operably interconnected between the winder mechanism and a respective side of the lift platform. Each hydraulic motor is reversible and communicably connected to a respective hydraulic pump, which transmits hydraulic fluid between the pump and the connected motor for operating the motor and selectively driving the connected winder mechanism and cable assembly to selectively raise and lower the lift platform. A respective restrictor valve interconnects each hydraulic pump and that pump's corresponding hydraulic motor. An angle inclination sensor detects the lateral inclination of the lift platform and transmits a corresponding signal to a controller, which selectively directs at least one restrictor valve to adjust the flow rate of hydraulic fluid transmitted between at least one pump and its respective hydraulic motor such that the lift platform is laterally leveled.
