Engineered for boats where vertical clearance is a premium, the Lectrotab SB-BK Short Actuator 24VDC packs powerful trim control into a compact, maintenance-free solution. Designed specifically for limited-height installations like swim platforms, this electric actuator delivers precise tab positioning without the clutter of hydraulic systems—and with no oil to leak.

Why this short actuator stands out

• Non-hydraulic, maintenance-free design. Enjoy reliable trim control without routine hydraulic maintenance or fluid leaks. The SB-BK keeps your boat tidy and trouble-free from install to operation.
• Corrosion-free, sun- and water-ready housing. The non-metallic exterior resists rust, salt, and UV exposure, staying robust in marine environments and out of service downtime.
• Self-contained, easy installation. All components live inside a permanently sealed housing. No parts to mount inside the bilge—simply connect the 24V power and go.
• Optimal for limited vertical height with a 6-second stroke. Quick, consistent lift and repositioning even in tight transom spaces, making it ideal for swim platforms and compact sterns.
• Proven performance with up to 1000 lbs of force. The SB-BK is load-tested to deliver solid tab engagement, hold position, and dependable leveling under speed or chine winds.
• Patented design features for reliability. The upper ram seal location is protected from fouling and barnacle growth, while the internal pressure equalization system maintains balanced, smooth operation.
• Quiet, controlled operation with built-in brake. Enjoy discreet trimming and peace of mind—the brake prevents unwanted tab movement when underway or backing down.
• Flexible mounting options. Choose standard or low-profile transom brackets to fit your boat’s layout and keep the trim tabs flush with the stern.
• Seamless upgrades to broader trim-tab systems. Seamlessly integrates into upgrades to popular hydraulic or electromechanical configurations, offering a smoother transition from older setups.

Ideal use cases

• Swim platforms that require precise, rapid adjustment without adding height or width to the boat’s transom.
• Compact transoms where space is at a premium but reliable trim control is essential for planing performance and stability.
• Owners who want a maintenance-free, leak-free alternative to traditional hydraulic trim tabs with long-term durability in sun and saltwater exposure.

What customers gain with the SB-BK/24V

The Lectrotab SB-BK Short Actuator 24VDC delivers a practical combination of speed, force, and built-in reliability.
