Lenco 12" x 30" Standard Trim Tab Kit without Switch Kit 12V

The Lenco 12" x 30" Standard Trim Tab Kit without Switch Kit 12V is a marine hydraulic leveling system engineered to stabilize vessel attitude and reduce hull porpoising across open water. Designed by Lenco Marine—a leader in precision marine trim technology—this 12-volt trim tab assembly serves operators of skiffs, center consoles, and mid-size recreational vessels who demand responsive handling and improved fuel efficiency. Trim tabs counteract bow rise at cruising speed and reduce water spray, delivering measurable gains in safety, comfort, and operational performance without requiring complex electrical architecture.

At the core of this kit sits Lenco's proven ballscrew actuator design, which converts 12-volt electrical input into linear hydraulic extension with superior reliability and repeatability compared to older piston-based systems. The standard mount configuration accommodates transom-mounted installation on vessels with moderate beam and deadrise, while the 12" x 30" tab dimensions provide optimal lift authority for single or dual-engine boats in the 18–35-foot range. The actuator mechanism operates silently under load, allowing real-time trim adjustment without audible cavitation or mechanical noise, and the sealed hydraulic reservoir resists corrosion in saltwater environments when properly maintained.

Retrofit and new-build integrators will appreciate that this kit ships without a switch module, allowing integration into existing helm control systems or OEM electrical architectures. Installation requires transom space, basic hydraulic line routing, and a dedicated 12V circuit with appropriate breaker protection; consult Lenco technical documentation and your vessel's electrical schematic before commencing work. This configuration is ideal for builders upgrading legacy systems or operators standardizing on Lenco platform components across multiple vessels. Weighing 35.7 lbs with compact packaging (13 x 6 x 44 inches), the trim tab assembly is manageable for two-person installation and compatible with fresh and saltwater service when fittings and seals are inspected annually.
