Electronic Remote Controls
Symptom Remedy
The ERC (electronic
remote control) lever is too
hard or too easy to move
out of neutral detent.
Adjust detent tension. See
Section 2, Dual Handle Electronic Remote Control
with DTS Trackpad Features and Operation
.
The ERC lever has too
much or too little
resistance through its
range of motion.
Adjust the handle tension screw. See
Section 2, Dual Handle Electronic
Remote Control with DTS Trackpad Features and Operation
.
The ERC lever increases
engine RPM, but does not
engage gears and the boat
does not move.
Key off and key on.
Check the "Throttle Only" button on the DTS trackpad. Put the ERC levers in
neutral and push the button to disengage, if the light is on.
Engage gears manually. See
Section 3, Gear Engagement—Emergency
Procedure
.
Contact your authorized Mercury MerCruiser dealer.
The ERC lever controls the
engine and drive, but does
not reach wide open
throttle.
If the engine only reaches 50% of WOT, check the "DOCKING" button on the DTS
trackpad. Put the handles in neutral and push the button to disengage, if light is
on.
Check VesselView to see if cruise control enabled. Disable cruise control.
Check for damage to the propeller. Check VesselView for Guardian fault codes
that indicate reduced engine power. If found, contact your authorized Mercury
MerCruiser dealer to ask if the propellers need to be changed.
The ERC lever controls the
engine and drive, but does
not respond in a linear
manner.
Check the "TROLL" button on the DTS track pad. Put the handles in Neutral and
push the "TROLL" button to disengage, if light is on.
Check whether dock mode or cruise control are on. If on, turn off or disengage.
When one ERC lever is
moved, both engines
respond.
Check the "1 LEVER" button on the DTS track pad. If the light is on, put the
handles in neutral and push the "1 LEVER" button to disengage.
The ERC control, joystick,
and steering wheel do not
function.
Press "HELM" on DTS track pad to restore helm control. (Multiple helm boats
only.)
