Lectrotab Smart Tabs SX Series 10.5 x 12 Trim Tabs for 21–25 ft Boats – SX10512-90
The Lectrotab Smart Tabs SX Series 10.5 x 12 (SX10512-90) are high-performance automatic trim tabs engineered to improve ride quality, handling, and efficiency on 21–25 foot boats powered by engines up to 350 HP. Designed to react instantly to changing water conditions, these self-adjusting trim tabs enhance performance without the need for electrical connections, switches, or hydraulics.
Built with durable composite trim plates and corrosion-resistant stainless steel hardware, Smart Tabs SX deliver reliable performance in both freshwater and saltwater environments. The system uses gas-actuated struts that automatically adjust tab position to reduce bow rise, improve hole shot, and maintain a level ride while underway. This results in faster planing, improved visibility, better fuel efficiency, and increased overall stability.
The 10.5 x 12 tab size provides excellent lift for mid-size boats, making them ideal for fishing boats, center consoles, dual consoles, and runabouts. Installation is straightforward with no wiring required, and once installed, the tabs operate automatically—responding instantly to load changes, speed, and sea conditions.
Trusted by boaters worldwide, Lectrotab Smart Tabs SX are an effective and affordable solution for improving performance, safety, and comfort on the water.
