Press → or → ↓ to F ISH ID S YMBOLS | ENT | EXIT | EXIT . Translated into complete English, step 1 above would mean: "Start on the Sonar Page. Press the Menu key then repeatedly [...]

7 Section 2: Installation & Accessories Preparations You can install the sonar system in some other order if you prefer, but we recommend this installation sequence: Caution: You should read over this entire installation section before drill- ing any holes in your vessel! 1. Determine the approximate location for the sonar unit, so you can plan[...]

8 adjustable strap. These are "kick-up" mounting brackets. They help prevent damage if the transducer strikes an object while the boat is moving. If the transducer does "kick-up" the bracket can easily be pushed back into place without tools. Read these instructions carefully before attempting the installation. Determine which o[...]

9 grit sandpaper, specially formulated epoxy adhesive available from LEI (see ordering information on the inside portion of the back cover). A sandwich hull also requires polyester resin. Selecting a Transducer Location 1. The location must be in the water at all times, at all operating speeds. 2. The transducer must be placed in a location that ha[...]

10 5. If possible, route the transducer cable away from other wiring on the boat. Electrical noise from engine wiring, bilge pumps and aerators can be displayed on the sonar's screen. Use caution when routing the trans- ducer cable around these wires. Good and poor transducer locations. How low should you go? For most situations, you should in[...]

11 However, there are times when you may need to adjust the transducer slightly higher or lower. The slots in the mounting brackets allow you to loosen the screws and slide the transducer up or down. If you fre- quently lose bottom signal lock while running at high speed the trans- ducer may be coming out of the water as you cross waves or wakes. M[...]

12 Lack of angle adjustment can be particularly troublesome on hulls that sit with the bow high when at rest or at slow trolling speeds. Third, a transducer CAN NOT shoot through wood and metal hulls. Those hulls require either a transom mount or a thru-hull installation. Fourth, if your Skimmer transducer has a built in temp sensor, it will only s[...]

13 Align plastic ratchets in bracket. B. Two-piece bracket: Locate the four plastic ratchets in the trans- ducer's hardware package. Press two ra tchets into the sides of the plastic bracket and two on either side of th e transducer as shown in the follow- ing illustrations. Notice there are lett ers molded into each ratchet. Place th e ra tc [...]

14 Add ratchets to bracket and transducer. 2. Aligning the transducer on the transom. A. One-piece bracket: Slide the transducer between the two ratch- ets. Temporarily slide the bolt though the transducer assembly and hold it against the transom. Looking at the transducer from the side, check to see if it will adjust so that its face is parallel t[...]

15 Insert bolt and check transducer position on transom. B. Two-piece bracket: Assemble the transducer and bracket as shown in the following figure. Temp orarily slide the bolt though the transducer assembly but don't tighte n the nut at this time. Hold the assembled transducer and bracket a gainst the transom. Looking at the transducer from t[...]

16 Assemble transducer and bracket. 3. Assembling the transducer. A. One-piece bracket: Once you determine the correct 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. B. Two-piece bracket: Once you determine the correct position for t[...]

17 Mark the center of each slot for the mounting screw pilot holes. You will drill one hole in the center of each slot. Drill the holes. For the one-piece bracket, use the #29 bit (for the #10 screws). For the two-piece bracket, use the #20 bit (for the #12 screws). Position transducer mount on transom and mark mounting holes. Side view shown at le[...]

18 tighten the lock nut! If you do, the transducer won't "kick-up" if it strikes an object in the water. Align transducer centerline with hull bottom and attach transducer to transom. Rear view of dual-frequency Skimmer shown. 6. Route the transducer cable throug h or over the transom to the sonar unit. Make sure to leave some slac k[...]

19 Caution: If you drill a hole in the transom for the cable, make sure it is lo- cated above the waterline. After installation, be sure to seal the hole with the same marine grade above- or below-waterline seal- ant used for the mounting screws. 7. Make a test run to determine the results. If the bottom is lost at high speed, or if noise appears o[...]

20 Transducer mounted on trolling motor, side view. Transducer Orientation and Fish Arches If you do not get good fish arches on your display, it could be because the transducer is not parallel with the ground when the boat is at rest in the water or at slow trolling speeds. Transducer angles and their effects on fish arches. Transducer aimed too f[...]

21 If the arch slopes up – but not back down – then the front of the trans- ducer is too high and needs to be lowered. If only the back half of the arch is printed, then the nose of the transducer is angled too far down and needs to be raised. NOTE: Periodically wash the transducer's face with soap and water to re- move any oil film. Oil a[...]

22 For example, some (but not all) ma nufacturers use a layer of fiberglass, then a core of balsa wood, finishing wi th an outer layer of fiberglass. Re- moving the inner layer of fiberglass an d the balsa wood core exposes the outer layer of fiberglass. The transduc er can then be epoxied directly to the outer layer of fiberglass. After th e epoxy[...]

23 harder (more rocky) the bottom, the easier it will be to get a second bot- tom signal. Don't touch the controls once they've been set. Example of a second bottom signal. Unit is in 30 feet of water, with range set at 80 feet and sensitivity set at 87 percent 2. Next, take the transducer out of the water and place it in the water in the[...]

24 4 . Most people can get good results by following steps 1 through 3, so this step is optional . If you want to make an extr a effort to be absolutely sure that your selected location will work under all conditions, make a test run with the boat on plane and observe th e bottom signal. You'll need to figure some way to prop the transducer in[...]

25 Epoxy transducer to hull. WARNING: Use only the epoxy available from LEI. It has been for- mulated to work with these installation procedures. Other epoxy types may be too thin or may not cure to the right consistency for optimum transducer performance. 2. The epoxy consists of the epoxy itself and a hardener. Remove the two compounds from the p[...]

26 3. Press the transducer into the epoxy, twisting and turning it to force any air bubbles out from under the transducer face. Stop pressing when you bottom out on the hull. When you're finished, the face of the trans- ducer should be parallel with the hull, with a minimum amount of ep- oxy between the hull and transducer. 4. Apply a weight, [...]
