2. Press 1 LEVER. The single‑lever light will turn off.

Synchronizing the Engines

Sync mode is an automatic engine‑synchronization feature that engages automatically at key‑up. Sync mode monitors the
position of both ERC levers. If both levers are within 10% of one another, all engines synchronize to the starboard engine's
RPM. The SmartCraft system will automatically disengage sync at the last 10% of the lever range to allow each engine the
ability to reach the maximum available RPM. Sync mode cannot engage until its minimum RPM is met.
To disengage sync mode:
1. Place the ERC levers in any detent.
2. Press SYNC.
To engage sync mode, press the sync button at any time.

Helm Transfer

Some boats are designed to allow control of the vessel from more than one location. These locations are commonly referred to
as helms or stations. Helm transfer is a term used to describe the method of transferring control from one helm (or station) to
another helm.
Avoid serious injury or death from loss of boat control. The boat operator should never leave the active station while engine is
in gear. Helm transfer should only be attempted while both stations are manned. One‑person helm transfer should only be
performed while engine is in neutral.
The helm transfer function allows the boat operator to select which helm is in control of the vessel. Before a transfer can be
initiated, the ERC levers at the active helm and at the helm intended for the transfer must be in the neutral position.
NOTE: If you attempt to transfer helm control when the ERC levers are not in neutral, a beep will sound and the helm transfer
will not succeed until the levers at the helms are moved to neutral and the transfer is requested again.
Some fault codes may appear on the Mercury‑approved multifunction display if other control or navigation functions are
attempted after the helm transfer procedure is started. To remove the fault codes it may be necessary to cycle the key switch
off and on, and then restart the helm transfer procedure. Ensure that other control and navigation inputs are performed after the
helm transfer is complete to avoid setting fault codes.
The ERC levers must be in neutral to perform a helm transfer. While in neutral your vessel could drift and collide with objects
nearby resulting in damage. Keep an adequate look out while performing the helm transfer.
To avoid damage, use extra care when attempting a helm transfer while the vessel is close to docks, piers, or other fixed items
or when near other vessels.

Electrical System Overload Protection

If an electrical system overload occurs, a fuse will fail or the circuit breaker will open. The cause must be found and corrected
before replacing the fuse or resetting the circuit breaker.
