Introduction to Active Trim

Active Trim is Mercury Marine's patented GPS‑based automatic trim system.
This intuitive, hands‑free system continually adjusts engine or drive trim for
changes in operating conditions to improve performance, fuel economy, and
ease of operation. It responds to boat maneuvers with precision and delivers a
better overall driving experience. No knowledge of trimming an engine or drive
is needed to take advantage of Active Trim.
• 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 anytime 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.
