Sync
Sync is an automatic engine synchronization feature that is always on unless it
is turned off. Sync monitors the position of both ERC levers. When both levers
are within 10% of one another, the port engine synchronizes to the starboard
engine's RPM. The SmartCraft system will automatically disengage sync after
95% of throttle position range to allow each engine the ability to reach
maximum available RPM. Sync cannot engage until the engines are at a
minimum speed.
The indicator light on the SYNC button is on when both engines are on. The
light is yellow at idle and 95% of throttle and when the engines are not
synchronized. The light turns red when the engines are synchronized.
The RPM display of VesselView also shows an orange icon under the RPM
numbers if the engines RPMs differ more than 10% of each other, and the icon
turns red when they are synchronized.
To disengage sync mode:
1. Place the ERC levers in any detent.
2. Press the SYNC button. The button light turns off.
To engage Sync mode, press the SYNC button at any time.
