Sync; Transfer (Boats Equipped With Dual Helms) - Mercury MerCruiser Series Manual

Sync

Sync is an automatic engine synchronization feature that is always on unless it is manually 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.

Transfer (Boats equipped with dual helms)

The TRANSFER button allows the boat operator to transfer control of the boat from the active helm to the inactive helm on
boats equipped with dual helms. Refer to Helm Transfer.
