The Nauticus Smart Tab ST780-20 trim tabs are a breakthrough automatic trim system designed for boats 10-12 feet in length with 8-18 HP outboard motors. Unlike traditional hydraulic or electric trim tabs that require constant manual adjustment, Smart Tabs utilize innovative nitrogen gas actuator technology to automatically adjust based on boat speed, loading, and maneuvering conditions.
Automatic Operation:
Smart Tabs require no switches, hydraulics, or operator input while underway. The nitrogen gas actuator provides lift at the stern by holding the 7" x 8" trim plate down during acceleration. As boat speed increases, water pressure pushes against the trim plates, creating lift that minimizes bow rise and enables quick planing. Once water pressure exceeds the actuator's load rating, the plates move to a horizontal position, eliminating drag at cruising speeds.
Performance Benefits:
- Reduce minimum planing speed by up to 33%
- Faster acceleration and hole shot performance
- Increased top speed potential
- Level, more comfortable ride at lower speeds
- Improved fuel economy and handling
- Enhanced stability in turns and rough water
- Eliminates porpoising, sliding, and chine walking
Speed-Regulated Stabilization:
Smart Tabs function as dynamic boat stabilizers throughout the entire speed range. The internal valve system dampens trim plate movement to prevent instant reactions to minor water pressure changes, providing smooth, undetectable adjustments. This continuous automatic adjustment acts like shock absorbers, delivering remarkable stability when crossing waves, cornering, and running at maximum speeds.
Simple Installation:
Installation can be completed in less than an hour with basic tools: electric drill, small drill bit, Phillips screwdriver, and two wrenches. No through-hull drilling is required. All mounting hardware, detailed instructions, and installation templates are included in the kit.
