Optional Speed Sensor Installation
All the units in this series can display speed and distance traveled,
these features require a speed sensor which may or may not come
packaged with your unit. If you wish to purchase an optional additional
sensor for your unit, refer to the accessory ordering information inside
the back cover of this manual. The following instructions describe how
to install the speed sensor.
Recommended tools for this job include: drill, 7/8" drill bit, 1/8" drill bit
for pilot holes, screwdriver. Required supplies for this job include: four
#8 stainless steel wood screws (3/4" long), high quality, marine grade
above- or below-waterline caulking compound.
First find a location on the boat's transom where the water flow is
smoothest. Don't mount the sensor behind strakes or ribs. These will
disturb the water flow to the speed sensor. Make sure the sensor will
remain in the water when the boat is on plane. Also make sure the lo-
cation doesn't interfere with the boat's trailer. Typically, the sensor is
mounted about one foot to the side of the transom's centerline.
Once you've determined the proper location for the unit, place the sen-
sor on the transom. The bottom of the bracket should be flush with the
hull's bottom. Using the sensor as a template, mark the hull for the
screws' pilot holes. Drill four 1/8" holes, one in each end of the slots.
Mount the sensor to the hull using #8 stainless steel wood screws (not
included). Use a high quality, marine grade above- or below-waterline
caulking compound to seal the screws. Make sure the sensor is flush
with the bottom of the hull and tighten the screws.
