Bennett 1812 Hydraulic Trim Tab Set
The Bennett 1812 trim tab kit includes two thru-transom actuators, two stainless steel trim tabs, a hydraulic power unit, and all required wiring, tubing, hardware, and installation instructions. This 18″ x 12″ tab setup is designed for reliable hydraulic operation with control sold separately. It supports standard 12V systems and aims to deliver predictable hydrodynamic behavior across typical boating conditions. Suitable for boats needing a robust, factory-supported hydraulic system with straightforward installation and durable components.
Bennett SLT10 Self-Leveling Tab System
The Bennett SLT10 is designed to help boats get on plane faster while reducing pounding and engine labor. Best for vessels longer than 17 feet, its pre-set 90-pound springs respond to water pressure and speed to deploy trim precisely as needed. Benefits include improved hole shot, smoother running attitude, and enhanced fuel efficiency due to better trim control. The automated self-leveling capability makes it a strong choice for boats operating in variable conditions without manual trim input.
Bennett 1212ATP Hydraulic Trim Tabs With Auto Trim Pro
The 1212ATP option brings Auto Trim Pro capabilities to hydraulic trim tabs, featuring automatic trim responses and simplified control. While the product listing is brief, its integration with Bennett’s hydraulic platform aims to offer reliable operation, consistent tab positioning, and user-friendly adjustment through the Auto Trim functionality. This can reduce manual trimming demands for boats encountering changing loads or water conditions.
Bennett Marine Bolt Electric Trim Tab System 12″ x 12″
The Bolt 12″ x 12″ electric trim tab system includes integrated helm control, two actuators with 6 ft wiring harnesses, and two stainless steel trim tabs with mounting hardware. This completely waterproof, submersible, and maintenance-free kit features an integrated helm control with All Up/All Down buttons and trim tab LEDs. Auto tab retraction works when ignition is off, helping to protect tabs and simplify operation in variable conditions.
Bennett Marine 3004.0288 129 Hydraulic Trim Tab Set
This 12″ x 9″ hydraulic trim tab set provides a complete kit with two thru-transom actuators, two stainless steel trim tabs, a hydraulic power unit, wiring, tubing, hardware, and installation instructions. Control is sold separately, which gives builders flexibility in selecting their preferred helm or control interface while ensuring a robust hydraulic platform remains at the core of performance gains.
Bennett Marine 2412E Hydraulic Trim Tab Set
The Bennett 2412E provides Euro-style control with adjustable trim tabs. This set focuses on giving operators versatile control with the aesthetic of a modern helm setup. The hydraulic system, blades, and actuators are designed for diverse hull types, allowing individualized trim adjustments to achieve a precise cruising attitude under varying loads and speeds. The 24″ x 12″ tab size is well-suited for mid-to-large bow sections where lift and trim changes have a meaningful impact on ride quality.
Buying Guide: Key Purchase Considerations and Comparisons
Hydraulic trim tabs are a long-term investment in ride quality and efficiency. When comparing options, consider:
- Boat size and weight: Larger boats benefit from bigger tabs or multiple actuators to provide adequate lift and leverage.
- Tab size and placement: Tab dimensions affect the range of trim adjustment; ensure mounting locations align with factory recommendations.
- Actuator system and power unit: Hydraulic systems rely on a power unit and actuators; check electrical compatibility (12V) and availability of spare parts.
- Control options: Some sets include integrated helm controls; others require separate control hardware. Auto-trim or self-leveling features add convenience for variable loads and sea states.
- Installation complexity: Complete kits with mounting hardware, wiring harnesses, and clear instructions simplify installation, especially for DIY installers.
- Maintenance and durability: Stainless steel trim tabs and corrosion-resistant actuators improve longevity in saltwater environments.
- Warranty and service: Look for manufacturers offering comprehensive warranties and local service support in the United States.
Compared to non-hydraulic or electric-only options, hydraulic trim tabs generally provide consistent performance under heavy loads and rough seas, with smoother responses and fewer manual adjustments required during operation. When selecting, balance initial cost with anticipated lifetime maintenance, replacement parts availability, and the overall fit for your vessel’s hull design and typical cruising profile.
