Nauticus ST780-20 Smart Tab 7 x 8 Self-Leveling Trim Tab Kit for Boats 12-16 ft, 40-80 HP

The Nauticus ST780-20 Smart Tab is a self-leveling trim tab kit built for boats 12 to 16 feet in length running 2 or 4 stroke engines rated from 40 HP up to 80 HP. It is recommended for use on Bay, Bow Rider, Fish, Flats, RIBs, and Ski boats. Unlike manually adjusted trim tabs, the Smart Tab system uses self-contained nitrogen gas actuators to automatically level the boat as speed and load conditions change, helping the hull get on plane with less bow rise and a more level ride.

Each tab plane measures 7 inches wide by 8 inches deep. The kit's structural components are stainless steel, and the actuators are protected by rubber boot seals for extended service life. The complete kit contains everything needed for installation: the stainless steel tab hardware, the nitrogen gas actuators with rubber boot seals, and a full owner's/installation manual. Nauticus backs the ST780-20 with a manufacturer's warranty covering metal components for five years and rubber boot covers and gas actuators for two years from the date of purchase.
