Ideal for walleye fishing, ProTroller Smart Tabs are designed for fishermen looking to reduce their trolling speed. By simply moving a lever, ProTroller Smart Tabs switch from a trim and stabilizer system to trolling breaks. With the levers in the down position, the plates drop down to create equal braking on both sides of the boat, providing the added benefit of tracking straight at ultra low speeds. Steering control is maintained because the propeller is not restricted as with other systems. Move the lever up to the running position and enjoy the performance and efficiency of automatic Smart Tabs - better ride and handling, faster acceleration, more top speed, and better fuel economy. Assembly and installation take only minutes.
