SERVICE BULLETIN

POTENTIAL FAILURE OF AUTOPILOT PUMPS
PRODUCTS AFFECTED
Garmin autopilot pumps:
010-00705-64: 1.2 L Pump
010-00705-63: 2.0 L Pump
010-00705-60 or 010-00705-62: SmartPump™
ISSUE
Garmin has discovered an issue where the models of autopilot pumps listed above may fail when improperly installed with
a hydraulic system that does not have a vented reservoir. These pumps may also fail if the return line from the pump to
the helm is pinched or crimped, or if hydraulic fluid flow in the return line is impeded by a blockage.
COMPLIANCE
Mandatory
WARRANTY INFORMATION
For affected pumps installed prior to May 1 2021, Garmin will reimburse up to three hours of labor and one hour of travel
st
to resolve the issue for installations in customer systems with unvented reservoirs.
RESOLUTION
The affected pumps must not be installed with a steering system that has an unvented reservoir. Before installing a
Garmin autopilot system that uses one of the affected pumps, verify that the vessel steering has a vented reservoir.
Typically, the vent hole is in the filler cap of the highest helm. If you are not clear as to whether the steering system is
vented, check with the manufacturer of the helm or the reservoir to verify.
If any of the affected pumps were installed with unvented reservoirs, immediately reach out to those customers so you
can evaluate the pump and add a vent to the system if needed.
Determining Whether or Not the Pump is Damaged
If a customer is experiencing performance issues with one of the listed pumps, for example, if after working correctly for a
time after installation the autopilot stops steering to one side or stops steering entirely, the pump may have been
damaged. To determine this:
For a 1.2L or a 2.0L Pump
Examine the installed pump for damage.
If the pump has been damaged, hydraulic fluid will be visibly leaking from the
screws , the motor manifold , or both.
If you determine that the pump has been damaged, it must be immediately
removed from the system and replaced after determining and correcting the
cause of the failure.
For a SmartPump
Attempt to steer the boat using the autopilot system and observe the
SmartPump.
If the pump does not steer the boat, or if it can only steer the boat to one side, the pump is most likely damaged. Perform
the following steps for examining the hydraulic system to help verify that the pump may have been damaged. If you
determine that the pump has been damaged, it must be immediately removed from the system and replaced after
determining and correcting the cause of the failure.
