Size: 6" x 8"Even small boats need trim tabs! SLT6 6 x 8 Tabs (Recommended for boats up to 17). Now you can enjoy the durability of trim tabs in a quick and easy, transom-only trim tab system. There are no hydraulics needed simply mount the two actuators and trim tabs and youre on your way to a smoother ride. The SLT reacts instantly to boat speed and water pressure by adding trim when its needed. At slower speeds, when the boat is trying to get on plane, the actuators hold the trim tabs down, which lifts the stern and simultaneously puts the boat at planing attitude. On plane, and as the boats speed increases, water pressure pushes the tabs up. You will enjoy a smoother ride while the SLT does all the work.
