T-H Marine Steering Trim Control Unit

The T-H Marine Steering Trim Control Unit is an essential precision component for serious boaters who demand responsive helm control and smooth trim adjustment on the water. Whether you're running a saltwater flats skiff, a freshwater bass boat, or a center console, this steering trim control unit eliminates guesswork and keeps your engine running at peak efficiency throughout your day on the water. Built by T-H Marine Supplies—a manufacturer trusted by professional guides and tournament anglers alike—this unit delivers the responsiveness and durability that matter when you're chasing fish or navigating challenging conditions.

This steering trim control unit integrates with your outboard's trim and tilt system to give you instant, fingertip command of engine angle and height. The dual-position design (model ST-1-DP) allows you to set two distinct trim angles—a shallow-water hole-shot position and a cruising trim setting—so you can maximize planing efficiency and fuel economy without constant adjustment. At just 0.6 pounds and engineered to withstand the vibration and salt spray of marine environments, the unit combines compact engineering with reliable switching action that responds immediately to your input, whether you're tightening your radius in shallow grass or adjusting trim on plane.

This control unit works seamlessly with standard T-H Marine steering systems and most late-model outboard trim circuits, making it ideal for retrofit or restoration projects where OEM controls are unavailable or worn. Installation is straightforward for anyone comfortable with basic marine wiring, and the compact 5 x 2 x 7-inch footprint fits easily into dashboard pods, center consoles, or armrest installations. Anglers upgrading older boats or seeking redundant trim control for long offshore runs will appreciate the reliability and precision this unit delivers when every inch of trim adjustment counts.
