Nauticus SX10512-90 Smart Tabs SX Composite Automatic Trim Tabs 10.5 x 12

The Nauticus SX10512-90 Smart Tabs SX composite trim tab set is an automatic trim tab system that self-adjusts to how you load and maneuver your boat. It needs no hydraulics and no electric switches, and requires no operator adjustment while underway. This 10.5 x 12 size is listed for 21-25' boats with 200-350 HP.

Key Features:

• Fully automatic operation: trim plates adjust on their own as speed and load change
• Molded composite construction: rust and corrosion free, with no maintenance in fresh or salt water
• Nitrogen gas actuator: holds the trim plate down during acceleration to provide lift at the stern; the amount of lift is set by the actuator load rating and the trim plate adjustment made at installation
• Internal valve system: dampens trim plate movement so minor changes in water pressure do not cause sudden reactions
• Tracking ribs: added to improve handling at higher speeds
• No through-hull drilling required

How It Works:

The trim plates start at a downward angle to maximize lift at slow speeds. As the boat accelerates, water pressure pushes the plates up, lifting the stern, reducing bow rise and helping the boat get on plane quickly. Once water pressure exceeds the actuator load rating, the plates move up to a horizontal position with the bottom of the boat to eliminate drag. At cruising speeds, the tabs keep adjusting to sea conditions to help reduce porpoising, chine walking and sliding in turns.

Performance Benefits:

• Reduces minimum planing speed by up to 33%
• Faster acceleration and increased top speed
• Level, more comfortable ride at lower speeds
• Improved fuel economy, handling and safety

Installation:

Installation is straightforward. Required tools are an electric drill, a small drill bit (3/16" bit), a Phillips screwdriver and two wrenches. All mounting hardware, instructions and templates are included.
