When in Doubt – Trim it Out!


With Performance Active Trim, new performance boaters are able to enjoy properly trimmed engines with virtually no learning curve, while experienced boaters will no longer need to monitor and adjust trim upon changes in boat speed or turns.

The integrated boat speed-based engine trim system specifically for performance applications where the gearcases are running partially surfaced. This intuitive, hands-free system automatically adjusts trim angle for changes in operating conditions to maximize performance and boat handling at speeds up to 50 mph.

Application Specific

  • Performance Active Trim is designed specifically for use with Mercury Racing outboards and sterndrives equipped with SmartCraft Digital Throttle & Shift (DTS) technology and running with gearcases partially surfaced.
  • DTS equipped Racing outboards and sterndrives being run in non-surfacing conditions should use Mercury Marine’s standard Active Trim DTS system.
  • Mercury Racing SmartCraft equipped outboards and sterndrives with mechanical throttle and shift should use the Mercury Active Trim Mechanical system.
