Bennett Marine Bolt Electric Trim Tab System
The Bolt Electric Trim Tab System features a complete kit with integrated helm control, two 12″ x 12″ stainless steel trim tabs, and mounting hardware. It includes actuators with 6 ft wire harnesses and waterproof connectors, providing a compact, maintenance-free electric option. The integrated helm control offers All Up and All Down buttons, auto tab retraction when the ignition is off, and LED trim tab position indicators for clear status visibility. The system is designed for quick installation with a 2.5″ stroke and a 6.39″ vertical transom space requirement.
Bennett Marine A1200S Hydraulic Actuator Assembly
Bennett A1200S actuators use strong yet flexible nylon/fiberglass hydraulic cylinders. The piston-like arms push trim tabs into position, with hydraulic fluid flow through a concealed hole in the upper hinge. This component is designed to work as part of Bennett’s hydraulic trim tab systems, offering reliable actuation and a compact footprint that fits tight transom spaces.
Bennett Bennett V351LK Conversion Kit
The V351LK kit provides a Lenco-to-Bennett conversion, including wiring harness, hydraulic power source, rocker switch, and actuators. It is designed for upgrading or converting compatible systems, offering an integrated approach to modern Bennett control hardware for reliable trim tab performance.
Lenco 9″ x 12″ Standard Trim Tab Kit
This Lenco kit includes standard 9″ x 12″ trim tabs with a dual rocker switch. It’s a solid option for boats around the 16–25 ft range, with straightforward installation and dependable trim tab performance suitable for many hull designs.
Bennett HYDBOLTCON Hydraulic to Bolt Electric Conversion Kit
The HYDBOLTCON kit enables a quick swap from hydraulic to bolt-electric control. It provides plug-and-play compatibility with existing Bennett rocker switches and trim planes, reducing downtime and installation complexity when upgrading older hydraulic systems to electronic actuation.
Besilo Self-Leveling Trim Tab System
Besilo’s 2-piece 10″ x 10″ self-leveling trim tabs auto-adjust with speed and water pressure. They reduce bow rise, improve fuel efficiency, and minimize hull pounding by adapting to varying loads and water conditions without requiring extensive user input. This system is designed for boats 16 feet and longer, offering an easier, hands-free trimming experience.
Buying Guide: Key Purchase Considerations
- System type and compatibility: Electric bolt-tab systems provide simple helm control, while hydraulic setups offer robust actuation. Check if your boat’s transom space and mounting pattern align with the kit’s dimensions.
- Control and wiring: Consider whether you prefer integrated helm controls or external switches, and ensure your boat’s power source (12V) matches the kit’s requirements.
- Tab size and hull form: Tab dimensions matter for effective trim. Match 9″–12″ tabs for small to mid-size boats, or larger 12″ panels for greater leverage on bigger hulls.
- Installation complexity: Conversion kits can simplify upgrading from hydraulic to electric. Look for “plug ’n play” features to minimize rewiring and drilling.
- Maintenance and warranty: Hydraulic actuators are generally durable but may require seals or lubrication over time. Review warranty terms for long-term support.
- Performance goals: If smooth, auto-leveling handling is a priority, self-leveling tabs offer hands-off stabilization, while dual rocker switches provide precise, independent control of each tab.
- Durability and environment: Waterproof connectors, corrosion resistance, and stainless steel tabs improve longevity in saltwater environments.
- Support and compatibility: Brands with established dealer networks and replacement parts (Bennett, Lenco) often ensure easier service and parts availability.
