Tools & Materials
Safety goggles
Dust mask
Scissors
Masking tape
Electric drill
Drill bits:
Bracket holes 4mm, #23, or 9/64"
Transom hole (optional) 18mm, 11/16", or 3/4"
Cable clamp holes 3mm or 1/8"
Straight edge
Wire cutters (some installations)
Marine sealant (suitable for below waterline)
Screwdrivers
Pencil
Zip-ties
Water-based antifouling paint (mandatory in salt water)
Pretest Temperature & Speed Functions
Connect the sensor to the instrument and spin the paddlewheel.
Check for the approximate air temperature and a speed reading. If
there is no reading(s) or it is inaccurate, check the connections
and test again. If there is still a problem, return the product to your
place of purchase.
Mounting Location
CAUTION: Do not mount in an area of turbulence or bubbles:
near water intake or discharge openings; behind strakes, struts,
fittings, or hull irregularities
CAUTION: Avoid mounting the sensor where the boat may be
supported during trailering, launching, hauling, or storage.
• For the best performance, the sensor must be in contact with
smooth water. To identify an area of clean water, observe the
water flow off the transom while the boat is underway.
• Allow headroom space above the bracket for it to release and
rotate the sensor upward.
• Mount the sensor as close to the centerline (keel) of the boat as
possible to ensure the sensor remains in the water when the
boat is turning.
• Single drive boat—Mount at least 75mm (3") beyond the
swing radius of the propeller (see Figure 2). The starboard
side where the propeller blades are moving downward is
preferred.
• Twin drive boat—Mount the sensor between the drives.

NOTE: Starboard
side of hull where
propeller blades are
moving downward is
preferred.
WARNING: Always wear safety goggles and a dust
mask when installing to prevent personal injury.
WARNING: When the boat is placed in the water,
immediately check for leaks around the screws and
any other holes drilled in the hull.
CAUTION: Never pull, carry, or hold the transducer by
the cable as this may sever internal connections.
CAUTION: Never strike the sensor with anything except
the palm of the hand. Never strike the paddlewheel.
CAUTION: Never use solvents. Cleaners, fuel, paint,
sealants, and other products may contain strong
solvents, such as acetone, which attack many plastics
greatly reducing their strength.
IMPORTANT: Please read the instructions completely
before proceeding with the installation. These
instructions supersede any other instructions in your
instrument manual if they differ.
