IMPORTANT: Multiple engine applications must have the Smart Tow Speedometer harness connected to the helm
harness connector identified with a tag stating "Gauges." When using a GPS antenna, the Smart Tow Speedometer
harness and the GPS antenna must be connected to the helm harness connector identified with a tag stating "Gauges"
through a junction box. This connection ensures the gauge and the antenna have power when any key is turned on.

SmartCraft GPS Mounting Considerations
The selection of a suitable mounting location is important for the optimal performance of the GPS unit. The mounting location
and position of the GPS should be:
•
Level with the earth’s horizontal plane
—This gives the GPS antenna the optimal view of satellites from all directions.
•
High enough to have a clear view of the sky to the horizon in all directions unblocked by masts or antennas
—
The GPS provides the best information when it has access to as many satellites as possible. Obstructions within 10
degrees of the horizon will not affect GPS reception.
•
At least 61 cm (24 in.) from VHF, satellite, or radar antennas
—Radio frequency transmissions from these antennas
can interfere with the reception of the GPS satellite signals.
•
Above or below the horizontal plane of any radar transmitter
—Avoids radar signal interference.
Installation
Mount the GPS antenna in a location without any overhead obstructions. The antenna can be mounted flush to the surface, or
on a 1.0 in. x 14 threads per inch standard marine pole mount.
