The Lenco 12″ x 18″ Standard Trim Tab Kit with LED Indicator Switch Kit – 12V (Model TT12X18I) is a complete marine electric trim tab system engineered to improve your boat’s ride quality, handling, and stability in a variety of sea conditions. Designed for small to mid-size powerboats, center consoles, cuddy cabins, and sport boats, this 12 V kit helps reduce bow rise, correct list, and promote more level, efficient cruising. 

Built for marine environments, the system includes durable 12-gauge laser-cut stainless steel trim tab plates and fully submersible electric actuators with 316 stainless steel rams and UV-resistant housings for long-lasting performance. The LED indicator switch kit provides real-time tab position feedback at the helm with high-intensity LEDs that automatically adjust brightness based on ambient light. A built-in retract feature returns tabs to a safe stowed position when power is removed, and the plug-and-play wiring harness simplifies installation.

Installation Pro-Tip:

For an 18-inch wide tab, ensuring the transom surface is flat is vital. If your transom has a slight radius, use extra 3M 5200 marine sealant to create a custom gasket behind the hinge to prevent stress on the stainless steel. To get the best performance, mount the tabs as far outboard as possible (usually 3–4" from the side) while ensuring they are at least 8 inches away from the propeller to avoid air cavitation.
