NOTE: Be sure to determine the waterline with an empty boat to ensure
thruster placement will keep the propeller a minimum of 5” (12 cm)
below the waterline in the worst case scenario.
The water stain on the hull is a good indication of typical waterline over a
range of conditions. Use the lowest indication of waterline if a water
mark is visible.
If no water stain is visible, the waterline must be marked while the boat
is in the water. With the boat completely unloaded (fuel tanks empty but
standard equipment in place), mark the waterline near the bow of the
boat with a grease pencil.
STEP 2: POSITION CLAMP STRAP
Dry fit the clamp strap such that the holes at the end of each flange are between 2”
and 6” (5 and 15.25 cm) above the waterline. Mark the position on the bow with
tape. Duct tape works well.
Verify that drilling the hole locations selected in step a. above will not damage
anything on the inside of the boat, for example a water tank or wiring etc. If in
doubt, contact the boat manufacturer.
WARNING: Verify that the proposed location to drill the anchor holes and cable
holes as determined above will not interfere or damage anything on
the inside of the hull.
Remove the two-sided tape backing on clamp strap.
Reposition the clamp strap at the location marked above and fasten in place using
the attached two-sided tape.
