The GEM GR2A Dual-Motor Remote with Auto-Stop brings advanced, hassle-free control to your boat lift system, letting you operate dual-motor hoists with a single push of a button. Designed for marine environments, this remote offers wireless radio-frequency control from up to 300 ft away, using a water-resistant floating transmitter and a weather-sealed, lockable control box built for long-term durability. Thanks to its Auto-Stop capability (when paired with a compatible limit switch), the lift automatically stops at preset upper or lower positions — eliminating guesswork and preventing over-travel. Compact, powerful, and user-friendly, the GR2A is an ideal upgrade for docks, piers, or marinas seeking reliable, safe, and convenient boat-lift operation. This product can be wired for 120, 208 and 240 volts; 30 amps max. It also comes with a transmitter GEM-7240 in the box. Autostop: The lift starts and stops on it's own. This requires an additional limit switch.
