SPEED/TEMPERATURE SENSOR INSTALLATION
(Ultra Classic Plus Only)
Mount the speed/temp sensor on the boat’s transom in a location where
the flow of water is the smoothest. There should be a minimum of
turbulence and air bubbles in the chosen location. The port (left) side of the
transom is preferred, however, the starboard (right) side can be used if
necessary. Do not mount the speed sensor behind strakes, ribs, or thru-
hull fittings. These will disturb the flow of water to the speed sensor. In a
typical installation, the speed sensor is mounted six to twelve inches from
the centerline of the hull. The sensor must always be in the water to
function properly. Make certain the chosen location is in the water even at
high speed or when the boat is on plane.
Once you determine the proper location, place the sensor on the transom.
Make certain the sensor’s bottom is flush with the bottom of the hull. Mark
the transom in four places, two in each slot. Drill a 5/32" mounting hole at
each location. Mount the sensor to the hull with four #10 stainless steel
screws. Use a good grade of caulking compound to seal the screws.
Adjust the sensor so it is flush with the bottom of the hull and tighten the
screws.
If the base of the transom has a radius, fill the gap between the transom
and the sensor with caulking compound. This will help ensure a smooth
water flow.
Route the sensor cable to the in-line connector on the Ultra Classic Plus’
power cable. The speed/temp sensor is now ready for use.
