Installation
To install the speed sensor, first find a location on the boat's transom
where the water flow is smoothest. Don't mount the paddle wheel
module behind strakes or ribs. These will disturb the water flow to the
paddle wheel.
Make sure the paddle wheel will remain in the water when the boat is
on plane. Also make sure the location doesn't interfere with the boat's
trailer. Typically, the paddle wheel module is mounted about one foot
(30.5 cm) to the side of the transom's centerline.

Once you've determined the proper location for the paddle wheel, place
it on the transom. The bottom of the bracket should be flush with the
hull's bottom. Using the paddle wheel's bracket as a template, mark the
hull for the screws' pilot holes. Drill four 1/8" (3 mm) holes, one in each
end of the slots.

Mount the paddle wheel module to the hull using four #8 stainless steel
wood screws. Use a high quality, marine grade above- or below-
waterline sealant to seal the screws. Make sure the paddle wheel
bracket is flush with the bottom of the hull and tighten the screws.
