At speeds above 50 mph, the system returns to manual trim to give the operator full control at high speeds. When speeds drop below 50 mph, the automatic system will resume control. Personal Active Trim provides five selectable trim profiles that let the operator personalize the system to his or her driving style and compensate for changes in boat load, operator preference and weather conditions. The Performance Active Trim profiles were designed to accommodate the sensitive trim range of surfacing outboard gear cases and sterndrives. Trim speed and range were designed exclusively for surfacing V-bottom and catamaran applications.
