Nauticus ST1290-80 Smart Tabs Automatic Trim Tabs 12 x 9 Gas Actuator

The Nauticus ST1290-80 Smart Tabs are 12 x 9 automatic trim tabs that adjust themselves as your boat loads up and maneuvers, so there are no hydraulics, no electric switches, and no operator adjustment while underway. They are listed for 18 to 22 ft boats with 150 to 240 HP.

Key Features:

• 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.
• Speed regulated: the plates start in a downward angle to maximize lift at slow speeds. As the boat accelerates, water pressure pushes the plates up, which lowers bow rise and helps the boat plane quickly.
• Low drag at speed: once water pressure exceeds the actuator load rating, the plates move up to a horizontal position, eliminating drag.
• Internal valve system: dampens trim plate movement so the tabs do not react to minor water pressure changes, for a smooth ride.
• Stability underway: the tabs keep adjusting to sea conditions, acting like shock absorbers to help with stability in turns and when crossing waves.
• Performance benefits: reduces minimum planing speed by up to 33%, provides faster acceleration, increases top speed, gives a level, more comfortable ride at lower speeds, and improves fuel economy, handling and safety.

Installation: Installation requires no through-hull drilling. An electric drill, small drill bit, Phillips screwdriver and two wrenches are all that is needed. Mounting hardware, instructions and templates are included.
