Yamaha Marine Systems Company (Bennett) 6BT500133800 BOLT Electric Trim Tab System 12 x 12

The Bennett BOLT 12" x 12" Electric Trim Tab System (Yamaha Marine part number 6BT500133800) is a high-performance, water-tight electric trim tab kit engineered for trailered powerboats. Designed for boats in the 17–28 foot range, this system helps operators plane faster, balance loads, improve fuel efficiency, and increase visibility — especially in congested waters or challenging weather conditions.

The BOLT system represents a major advancement over older electric trim tab designs, combining cutting-edge actuator technology with a robust, fully sealed housing that eliminates the water intrusion and marine growth issues common with legacy systems.

Key Features:

• 12" x 12" tab size — span (side-to-side) x chord (fore-to-aft) configuration
• Water-tight black nylon actuators — submersible, maintenance-free, and built for trouble-free long-term operation
• Concealed wiring — wires are threaded through the upper hinge, eliminating exposed wires in the marine environment
• Elevated main seal placement — protects against marine growth and water intrusion failures
• 12V DC operation — 750 lb. actuation force per tab
• 2.5" actuator stroke with 13.25" actuator length
• Quiet operation — runs quieter than competing electric trim tab systems
• Fast, tool-friendly installation — actuator does not require disassembly during mounting
• Lifetime warranty on electric actuators

What's Included:

• Two (2) 12V electric actuators with 6 ft. wire harnesses and waterproof connectors
• Two (2) stainless steel trim tab planes and mounting plates
• 20 ft. wire harness with waterproof connectors

Note: A helm control or rocker switch is required and sold separately. Bennett Electric Trim Tab sizes are listed in span x chord format — span is the side-to-side measurement and chord is the fore-to-aft measurement. Suitable for flatboats, center consoles, dual consoles, deck boats, bowriders, bass boats, and runabouts.
