Page 8: Transducer Installation
Transducer Installation These instructions will help you install your Skimmer transducer on a transom, on a trolling motor or inside a hull. Please read all instructions before proceeding with any installation. Your Skimmer transducer typically comes packaged with a one-piece stainless steel bracket for mounting it to the transom of your boat. -
Page 9: Selecting A Transducer Location
Selecting a Transducer Location 1. The transducer must be placed in a location that has a smooth flow of water at all times. If the transducer is to be mounted inside the hull, then the chosen location must be in the water at all times. If the transducer is not placed in a smooth flow of water, interference caused by bubbles and turbulence will show on the sonar's display in the form of random lines or dots whenever the boat is moving. - Page 10 CAUTION: Clamp the transducer cable to transom near the transducer. This will help prevent the transducer from entering the boat if it is knocked off at high speed. Good location Poor angle Good and poor transducer locations. How low should you go? For most situations, you should install your Skimmer transducer so that its centerline is level with the bottom of the boat hull.

to loosen the screws and slide the transducer up or down.) If you frequently lose bottom signal lock while running at high speed, the transducer may be coming out of the water as you cross waves or wakes. Move the transducer a little lower to help prevent this. If you cruise or fish around lots of structure and cover, your transducer may be frequently kicking up from object strikes. - Page 12 there are letters molded into each ratchet. Place each ratchet into the bracket with the letter "A" aligned with the dot stamped into the metal bracket. This position sets the transducer's coarse angle adjustment for a 14° transom. Most outboard and stern-drive transoms have a 14° angle. Align plastic ratchets in bracket.
- Page 13 Ratchets Insert bolt and check transducer position on transom. 3. Assembling the transducer. position for the ratchets, assemble the transducer as shown in the following figure. Don't tighten the lock nut at this time. Assemble transducer and bracket. 4. Drilling mounting holes. Hold the transducer and bracket assembly against the transom.
- Page 14 Transom Position transducer mount on transom and mark mounting holes. Side view shown at left and seen from above at right. 5. Attaching transducer to transom. Remove the transducer from the bracket and re-assemble it with the cable passing through the bracket over the bolt as shown in the following figures.
- Page 15 Flat-bottom hull Align transducer centerline with hull bottom and attach to transom. 6. Route the transducer cable through or over the transom to the sonar unit. Make sure to leave some slack in the cable at the transducer. If possible, route the transducer cable away from other wiring on the boat.

Page 16: Trolling Motor Bracket Installation
TROLLING MOTOR BRACKET INSTALLATION 1. Attach the optional TMB-S bracket to the transducer as shown in the following figure, using the hardware supplied with the transducer. (Note: The internal tooth washer is supplied with the TMB-S.) Bolt Attach motor mounting bracket to transducer. 2. - Page 17 the transducer is not parallel with the ground when the boat is at rest in the water or at slow trolling speeds. Transducer aimed too far back Full fish arch Transducer angles and their effects on fish arches. If the arch slopes up – but not back down – then the front of the transducer is too high and needs to be lowered.

Page 18: Shoot-Thru-Hull Preparation And Installation
SHOOT-THRU-HULL PREPARATION The transducer installation inside a fiberglass hull must be in an area that does not have air bubbles in the resin or separated fiberglass layers. The sonar signal must pass through solid fiberglass. A successful transducer installation can be made on hulls with flotation materials (such as plywood, balsa wood or foam) between layers of fiberglass if the material is removed from the chosen area. - Page 19 second bottom echo is seen on the display. (You will need to turn off both automatic and ASP.) Don't touch the controls once they've been set. Next, take the transducer out of the water and place it in the water in the sump of the boat.

Page 20: Power And Cable Connections
Sand this surface 2. Follow the instructions on the epoxy package and mix it thoroughly. Do not mix it too fast, because it will cause bubbles to form in the epoxy. Apply a small amount on the face of the transducer as shown above, then spread a small amount onto the sanded area on the hull. - Page 21 CAUTION: When using the unit in a saltwater environment, we strongly recommend that you shut off the power supply to the power cable when the unit is not in use. When the unit is turned off but still connected to a power supply, electrolysis can occur in the power cable plug.

Page 22: Mounting The Sonar Unit: In-Dash Or Bracket
For example, if you have to extend the power cable to the battery or power buss, attach one end of the fuse holder directly to the battery or power buss. This will protect both the unit and the power cable in the event of a short. - Page 23 For the Cuda 128 and Cuda 168 The Cuda 128 and Cuda 168 both use the same case and can be mounted in-dash using the removable scaled template inside the back cover of this manual (page 55).

Page 25: Bracket Installation
(See the following drawings, which show the dimensions of a gimbal-mounted Cuda 168EX sonar unit and a Cuda 128 or 168.) Holes in the bracket’s base allow wood screw or through-bolt mounting. - Page 26 location. This way, the bracket can be installed so that it covers the hole, holds the cable in position and results in a neat installation. Some customers, however, prefer to mount the bracket to the side of the cable hole — it's a matter of personal preference. After drilling the hole, pass the connector up through the hole from under the dash.
- Page 27 Tilt the unit to the desired viewing angle and tighten the knobs finger tight. For the Cuda 128 and Cuda 168 These units use a quick release mounting bracket. When you run the cable through the hole, make sure you allow enough slack for tilting the unit and attaching the connector.
- Page 28 Screw hole Power/transducer cable Cuda 128 and 168 quick release mounting bracket. Slots in the base allow routing the cable from beneath the mount. Attach the unit to the bracket by first connecting the power/transducer cable. Then, hold the sonar unit vertically and slide it onto the bracket from above.

The Cuda 128 and Cuda 168 use the optional PPP-12 portable power pack. In fact, the Cuda 128 Portable package includes the PPP- 12 and the transducer necessary for portable use.
- Page 31 After installing the batteries, close the case and plug the sonar unit's power cable into the socket on the battery case. "D" cell battery Install batteries in power case battery adapter. PPP-13 shown. Turn the sonar unit on. If it doesn't work, make sure the battery terminals are making good contact against the battery contacts.
- Page 32 If the batteries do lose a charge, you can sometimes restore them by placing them in a warm room or car interior. A better way is to replace them with batteries that have been kept warm. WARNING: Never heat the batteries over an open flame or direct hot air onto them.
- Page 33 Clean the chosen area of the hull before attaching the suction cup. Locate the transducer on the hull as shown in the following figure. Don't allow the bracket to extend below the hull, because water pressure against it can cause the suction cup to come off at speed. Moisten the cup, then press it onto the hull as firmly as possible.

Page 54: Troubleshooting
Troubleshooting If your unit is not working, or if you need technical help, please use the following troubleshooting section before contacting the factory customer service department. It may save you the trouble of returning your unit for repair. For contact information, refer to the last page, just inside the back cover of this manual. - Page 55 Weak bottom echo, digital readings erratic, or no fish signals: 1. Make certain the transducer is pointing straight down. Clean the face of the transducer. Oil, dirt and fuel can cause a film to form on the transducer, reducing its effectiveness. If the transducer is mounted inside the hull, be sure it is shooting through only one layer of fiberglass and that it is securely bonded to the hull.
- Page 56 spark plugs or routing the sonar unit's power and transducer cables away from other electrical wiring on the boat. No fish arches when the Fish I.D. feature is off: 1. Make certain the transducer is pointing straight down. This is the most common problem if a partial arch is displayed.
- Page 57 example, turn on the bilge pump and view the sonar display for noise. If no noise is present, turn the pump off, then turn on the VHF radio and transmit. Keep doing this until all electrical equipment has been turned on, their effect on the sonar display noted, then turned off. If you find noise interference from an electrical instrument, trolling motor, pump, or radio, try to isolate the problem.
