• As the boat accelerates, the engine or drive will trim out.
• As the boat decelerates, for example, while making a turn, the engine or
drive will trim in.
• Active Trim can be overridden at any time by using the regular, manual
trim buttons.
• Active Trim allows the boat operator to compensate for changes in boat
load, driver preferences, and weather conditions while maintaining full
automatic control.
