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, 5/8"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

the sensor cable through the same hole as the transducer cable, you will
need a 1" (25.4 mm) drill bit instead of the 5/8" drill bit.)
