TEMPERATURE PROBE ACCESSORY INSTALLATION
The Temperature Probe incorporates a
temperature sensitive probe in a high-
impact plastic housing. The module is
intended for installation on the transom,
and will work well on almost any boat.
In addition to the parts supplied, you will
need a hand drill with various bits,
marine-grade silicone sealant, and a
Phillips head screwdriver.
Install the temperature probe accessory:
1. Locate an area on the transom of your boat that will be 6” to 8” or farther from
the transducer(s). This area must also maintain contact with the water, even at
high speeds. Do not mount the sensor directly in front of the propeller or
outdrive, and make sure that there are no protrusions such as ribs, rows of
rivets, or transducers directly forward of the mounting location, as these may
affect the flow of water over the temperature probe.
2. Align the sensor in the clamp, and align it on the transom so that the lower edge
is flush with the hull of the boat, and mark the hole location.
3. On fiberglass hulls, it is best to start with a smaller drill bit and use progressively
larger bits to reduce the chance of chipping or flaking the outer coating. Drill a
1/8” (3 mm) mounting hole approximately 3/4” (19 mm) deep.
4. Seal the mounting holes with marine-grade silicone sealant, and attach the
sensor to the transom using the screw provided. Hand tighten only!
Routing the cable to the control head:
1. You may route the cable over the top of the transom, or drill a 5/8” (16 mm)
diameter hole in the transom directly above the sensor and above the waterline
to route cable through. Use the cable clamps provided to secure the cable to the
transom of the boat. If you use a through-hole, then also use the included
escutcheon plate to dress the hole.
NOTE: On fiberglass hulls, it is best to start with a smaller drill bit and use progressively
larger drill bits to reduce the chance of chipping or flaking the outer coating.
2. All mounting screws not specified require a 9/64” (3.5 mm) pilot hole drilled
approximately 5/8” (16 mm) deep. Additionally, seal any hole drilled in the
transom of the boat with marine-grade silicone sealant (not included).
