Lenco’s 9″ x 12″ standard trim tab kit offers a solid balance of performance and value, highlighted by a double rocker switch for intuitive control. The kit includes durable tabs and mounting hardware suitable for a variety of small-to-mid sized boats. While the listing emphasizes simplicity and reliability, users should verify fitment with hull curvature and mounting space to ensure optimal performance at planing speeds.
Bolt Electric Trim Tab System – 12″ x 9″
The Bolt 12″ x 9″ trim tab system provides a complete kit with integrated helm control, two actuators, six-foot harnesses, and waterproof connectors. The 12-volt actuators are designed for durability, with a waterproof, maintenance-free design. The system emphasizes ease of installation and operation, with clearly labeled control wiring and LED indicators to help monitor trim tab positions during operation.
Bennett SLT10 Self-Leveling Trim Tab System
The SLT10 self-leveling system is designed for boats between 17′ and 20′. Its actuators are pre-set with a 90-lb spring, enabling automated adjustments in response to speed and water pressure to optimize hole shot and reduce engine strain. Benefits include faster planing, improved fuel efficiency, and reduced pounding. This system is ideal for planning hulls that require precise trim response at varying speeds and sea states.
Bolt Electric Trim Tab System – 24″ x 12″
The 24″ x 12″ Bolt system combines a large surface area with integrated helm control, two actuators, six-foot harnesses, and heavy-duty stainless steel tabs. The XL kit is designed for bigger boats or vessels requiring more substantial trim power and balance. The waterproof actuators and integrated control make for straightforward wiring and dependable operation, with Bennett’s reputation for durable trim systems.
Buying Guide
- Boat size and hull type: Larger boats often require bigger trim tabs (e.g., 24″ x 12″) for effective control at planing speeds, while smaller boats can perform well with 9″ x 12″ or 12″ x 9″ configurations.
- Control integration: Consider whether you prefer integrated helm controls with all-up/all-down and LED position indicators, or if you’re comfortable with basic toggle controls.
- Mounting space and space constraints: Edge-mount versus standard configurations affect installation on limited transoms. Edge-mount kits may fit tighter spaces but require precise alignment.
- Actuator durability: Look for submersible, fully watertight actuators with corrosion-resistant materials to endure saltwater use and repeated cycles.
- Auto-leveling and speed compensation: Self-leveling or auto-adjust features help maintain a平 stable ride at varying speeds and sea conditions but may be more complex and costly.
- Warranty and serviceability: Long-term warranties on actuators and components can reduce maintenance concerns and replacement costs.
- Installation scope: Some complete kits include mounting hardware, wiring harnesses, and a standalone helm control. Ensure your boat’s electrical system can handle the current draw and wiring needs.
- Brand ecosystem: Bennett Marine and Lenco Marine are well-known for durable trim tab systems; consider brand familiarity and existing if you plan to upgrade.
When selecting electric trim tabs, align your choice with your boat’s length, expected load, and typical operating speeds. A system with integrated helm control simplifies operation, while larger tabs provide stronger adjustments for bigger craft. Reliability features, such as waterproof actuators and robust mounting hardware, contribute to longer service life in saltwater environments.
