SMARTPUMP

INSTALLATION INSTRUCTIONS

Important Safety Information

 WARNING

See the Important Safety and Product Information guide in the product box for product warnings and other 
important information.
You are responsible for the safe and prudent operation of your vessel. The autopilot is a tool that enhances 
your capability to operate your boat. It does not relieve you of the responsibility of safely operating your boat. 
Avoid navigational hazards and never leave the helm unattended.
Always be prepared to promptly regain manual control of your boat.

 CAUTION

To avoid possible personal injury, always wear safety goggles, ear protection, and a dust mask when drilling, 
cutting, or sanding.

NOTICE

To avoid damage to your boat, the autopilot system should be installed by a qualified marine installer. Specific 
knowledge of marine steering and electrical systems is required for proper installation.
When drilling or cutting, always check what is on the opposite side of the surface to avoid damaging the vessel.
This pump is only for use with Garmin

®

 autopilot systems. Attempting to use this pump with any other system 

may damage the system, the pump, or the vessel.
This pump must not be installed with a steering system that has an unvented reservoir, because it will damage 
the pump. Before installing the pump, you must 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, you should check with the manufacturer of the helm or the reservoir to verify.
The pump must be installed in a dry location, protected from water and the weather.

The SmartPump steers your boat by interacting with the hydraulic steering system, based on commands from 
the autopilot system.

Autopilot Software Updates

After completing the autopilot installation, you should update the software before performing the configuration 
process.
If you connected the autopilot system to a NMEA 2000

®

 network with a Garmin chartplotter, you can update the 

software using the chartplotter.
If you did not connect the autopilot system to a NMEA 2000 network with a Garmin chartplotter, you must use a 
NMEA 2000 Network Updater (sold separately). Go to 

support.garmin.com

 for update information.
