Nauticus ST980-40 Smart Tab Trim Tabs 9 X 8 f/12-16' Boats w/40-80 HP

The Nauticus ST980-40 Smart Tab Trim Tabs are automatic trim tabs engineered for recreational fishing boats in the 12–16-foot class with engines rated 40–80 horsepower. Unlike manual trim tab systems that require constant operator adjustment, the ST980-40 features self-adjusting technology that automatically compensates for changes in load, speed, and sea conditions, delivering improved stability, reduced fuel consumption, and better overall boat handling without pilot intervention.

Built with 9 × 8-inch tabs, the ST980-40 is sized specifically for smaller center console and open boats where traditional manual trim systems waste fuel and create porpoising. The smart tab design detects changes in trim angle and automatically deploys to the optimal position, reducing bow rise, improving draft efficiency, and lowering operating fuel costs. Installation is straightforward on standard outboard and jet drive configurations. The system's compact profile means minimal interference with engine cowling or transom access.

The Nauticus ST980-40 trim tabs for sale are ideal for recreational boaters who fish offshore, run coastal routes, or spend extended time at variable speeds and loading conditions. Operators appreciate the fuel economy gains that accumulate over a full season, the reduced fatigue from not manually adjusting trim continuously, and the improved ride quality when running in choppy conditions. The automatic deployment means less attention to engine trim and more focus on fishing or navigation.

Trim tabs remain standard equipment on well-maintained pleasure and fishing vessels because they address a fundamental problem: boats running in displacement or semi-planing mode require constant trim adjustment to maintain speed and comfort. The ST980-40 removes that workload while delivering the performance improvement a manual system provides—at a price point competitive with quality manual trim tabs. Weighing 4 pounds and measuring 9 × 5 × 12 inches, the control module is compact enough for tight engine compartments.
