Nauticus ST980-30 Smart Tabs Automatic Trim Tabs 9 x 8 for 30-40 HP Boats

The Nauticus Smart Tabs ST980-30 are automatic boat trim tabs, sized 9 x 8 and intended for 13-15' boats with 30-40 HP. They adjust on their own as you load and maneuver the boat, so there are no hydraulics, no electric switches and no operator adjustment while underway.

How It Works:

• A nitrogen gas actuator provides lift at the stern by holding the trim plate down during acceleration.
• The amount of lift is set by the actuator load rating and the trim plate adjustment made at installation.
• The trim plates start in a downward angle to maximize lift at slow speeds.
• As the boat accelerates, water pressure pushes the plates up, which helps minimize bow rise and lets the boat plane quickly.
• Once water pressure exceeds the actuator load rating, the plates move up to a horizontal position with the bottom of the boat, eliminating drag.
• An internal valve system dampens plate movement, so the tabs do not react to minor changes in water pressure.

Performance Benefits:

• Reduces minimum planing speed by up to 33%
• Faster acceleration and increased top speed
• A level, more comfortable ride at lower speeds
• Improved fuel economy, handling and safety
• Works like a shock absorber while cruising, helping reduce porpoising, sliding and chine walking

Simple Installation: Smart Tabs require no through-hull drilling. Installation needs an electric drill, a small drill bit, a Phillips screwdriver and two wrenches. All mounting hardware, instructions and templates are included.
