SYNCHRONIZING ENGINES
The auto synchronizing feature, when engaged, will automatically
adjust all engine speeds to match the speed of the starboard
engine.
Press the "SYNC" button on the CAN trackpad to turn auto
synchronization on or off. When the sync LED is yellow, the
"SYNC" button has been pressed, but the conditions are not right
for auto synchronization to engage. When the sync LED turns red,
engine synchronization has been engaged. The engines will
remain synchronized as long as engine speed is over 900 RPM for
two seconds, remote control handles are positioned within 10% of
each other, and the engines are below 95% throttle opening.
