SMART TACHOMETER, SMART SPEEDOMETER INSTALLATION
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.
