Nautical Technologies SX10512-70 Smart Tab SX Automatic Trim Tabs 10.5" x 12" with 70lb Actuator

The Nautical Technologies SX10512-70 Smart Tab SX is a fully automatic trim tab system designed for 21-25 foot boats with 150-220 HP outboard or stern drive engines. This breakthrough technology operates completely automatically, requiring no operator adjustment while underway, as the trim tabs self-adjust according to how you load and maneuver your boat.

Key Features:

• Nitrogen gas actuator (70lb rating) provides lift at the stern by holding the trim plate down during acceleration, with lift amount determined by actuator load rating and trim plate adjustment set during installation
• Molded composite construction provides rust and corrosion-free benefits for superior durability in fresh or saltwater
• Internal valve system dampens trim plate movement, eliminating instant reaction to minor water pressure variances for smooth, undetectable response to boat speed changes
• Functions like shock absorbers, providing stability in turns, while crossing waves, cruising, and running at maximum speeds—eliminating sliding, porpoising, and chine walking
• Requires no through-hull drilling for installation
• 10.5" x 12" trim plate dimensions

What's Included:

• Complete kit with all mounting hardware, installation instructions, and templates
• Pair of Smart Tab SX trim tabs with 70lb actuators

Installation is straightforward—most boat owners can complete installation in less than an hour using basic tools (electric drill, small drill bit, phillips screwdriver, and two wrenches), while professional installers typically finish in 30 minutes or less. No hydraulics or electric switches required for operation, making this an economical alternative to traditional electric trim tab systems.
