NOTE: This accessory requires drilling a hole in the hull of the boat; therefore, installation should be performed by a qualified marine technician.

In addition to the hardware supplied with your accessory, you will need a drill, a small drill bit for a pilot hole, a 2" hole saw, a level, and marine-grade silicone sealant.

Installation

Perform the procedures in the following sections to install the Temp/Speed Gauge on your boat.

1. Testing the Temp/Speed Gauge Prior to Installation

Prior to installation, test the Temp/Speed Gauge to make sure that no damage occurred during shipping.

1. After connecting the temp/speed gauge to the control head, hold the gauge in the water over the side of the boat to confirm proper operation. If the gauge is working properly, the control head will begin displaying water temperature immediately.

2. Locating the Temp/Speed Gauge Mounting Position

You must first determine the best location on the transom to install the Temp/Speed Gauge. It is very important to locate the gauge in an area that is relatively free of turbulent water, constantly submerged, and positioned to allow you to trailer the boat without damaging the gauge.

The best location will be aft midship, as close to the centerline of the boat as possible. The gauge should be mounted forward of the prop(s) on inboard boats, and separate from other transducers, strakes, rivets, ribs, or other protrusions.

Inside the boat, there must be room to access the mounting location for installation and cable routing. Notice that the Temp/Speed Gauge is removable from the threaded housing - adequate overhead space must be available to remove this insert.

3. Attaching the Temp/Speed Gauge

1. From the outside of the hull, drill a small pilot hole (smaller than the centering bit of your drill bit or hole saw), at the mounting location you selected in procedure 2.

2. Use the pilot hole (from the outside of the hull) to drill a 2" hole.

3. Thoroughly clean and deburr the drilled hole and clean the outside of the hull.

4. Disassemble the temp/speed gauge and wing nut from the threaded housing.

5. Apply a generous amount of marine-grade silicone sealant inside the drilled hole and along the mating surfaces of the threaded housing.

6. Insert the threaded housing through the drilled hole with the clevis pin holes oriented with the length of the boat.

7. Slide the wing nut over the threaded housing, then Hand Tighten the wing nut ONLY until the assembly is firmly seated, then tighten NO MORE than 1/8 of an additional turn. Make sure that the orientation of the clevis pin holes have not changed.

CAUTION: To avoid damage, do not overtighten the wing nut. If the hull is wood, it will swell when wet.

NOTE: Remove the excess marine-grade silicone sealant from the outside of the hull to ensure smooth water flow over the

temp/speed gauge. Allow the sealant to dry according to the sealant manufacturer's recommendation before using your boat. Then, check for leaks over the next 24 hours, and re-install the temp/speed gauge if necessary.

8. Slide two of the O-Rings over the gauge body and seat them into each groove. Lubricate the O-Rings and the inside of the threaded housing. Orient the gauge so that the arrow on the flange points forward, and slide the gauge fully into the threaded housing.

9. Insert the clevis pin through the holes in the threaded housing and gauge. Insert the ring clip through the hole on the clevis pin.

10. Loop the chain around the cable coming from the gauge, and secure each end into the slots on the wing nut.

4. Routing the Cable

The temp/speed gauge cable must be routed to the point where the control head is mounted.

NOTE: Your boat may have a pre-existing wiring channel or conduit that you can use for the cable.

CAUTION! Do not cut or shorten the cable, and try not to damage the cable insulation. Route the cable as far as possible

from any VHF radio antenna cables or tachometer cables to reduce the possibility of interference. If the cable is too short, extension cables are available to extend the cable up to a total of 50'. For assistance, contact the Customer Resource Center at www.humminbird.com or call 1-800-633-1468 for more information.

1. Route and secure the cable, avoiding areas where it may be damaged or interfere with normal boating operations.

5. Connecting the Cable

Insert the temp/speed gauge cable into the appropriate terminal slot. The cable connectors are labeled, and there are corresponding labels on the cable holder on the rear of the control head. The slots are keyed to prevent reversed installation, so be careful not to force the connector into the holder.

Your Temp/Speed Gauge is now ready for operation.

Removing the Temp/Speed Gauge

Use the steps below to remove the Temp/Speed Gauge from your boat.

1. Carefully disconnect the temp/speed gauge cable from the control head.

2. Disassemble the temp/speed gauge and wing nut from the threaded housing.

3. Slide two of the O-Rings over the plug (included) and seat them into each groove of the plug body. Lubricate the ORings and the inside of the threaded housing. Orient the plug so that the arrow on the flange points forward, and slide the plug fully into the threaded housing.

4. Insert the clevis pin through the holes in the threaded housing and plug. Insert the ring clip through the hole in the clevis pin.
