Page 5: Section1: Installation
Section 1: Installation Thank you for buying a Lowrance sonar designed for both professional and novice fishermen. All Lowrance sonars have an automatic mode that finds and displays the bottom, fish, underwater structure and more – right out of the box. All you have to do is press the on ( NOTICE! The storage and operation temperature range for your unit is from... - Page 6 installation methods is right for your boat. Use extreme care if mounting the transducer inside the hull, because once it is epoxied into position, the transducer usually cannot be removed. Remember, the transducer installation is the most critical part of a sonar installation! Your Skimmer transducer typically comes packaged with a one-piece stainless steel bracket for mounting it to the transom of your boat.
- Page 7 NOTE: Some aluminum boats with strakes or ribs on the outside of the hull create large amounts of turbulence at high speed. These boats typically have large outboard motors capable of propelling the boat at speeds faster than 35 mph. Typically, a good transom location on aluminum boats is between the ribs closest to the engine.
- Page 8 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. This will usually give you the best combination of smooth water flow and protection from bangs and bumps.

Page 9: Transom Transducer Assembly And Mounting
However, the shoot-thru-hull installation does have its drawbacks. First, some loss of sensitivity does occur, even on the best hulls. This varies from hull to hull, even from different installations on the same hull. This is caused by differences in hull lay-up and construction. Second, the transducer angle cannot be adjusted for the best fish arches on your sonar display. - Page 10 If the transducer's face isn't parallel with the ground, remove the transducer and ratchets from the bracket. Place the ratchets into the holes in the bracket with the letter "B" aligned with the dot stamped in the bracket. Reassemble the transducer and bracket and place them against the transom.
- Page 11 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 using the #29 bit (for the #10 screws). Transom Position transducer mount on transom and mark mounting holes. Side view shown at left and seen from above at right.

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 13 Bolt Attach motor mounting bracket to transducer. 2. Slide the adjustable strap supplied with the TMB-S through the slot in the transducer bracket and wrap it around the trolling motor. Position the transducer to aim straight down when the motor is in the water.

Page 14: Transducer Orientation And Fish Arches
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. If the arch slopes up –... - Page 15 hours, fill the remaining space with polyester resin. When the job is finished, the hull is watertight and structurally sound. Remember, the sonar signal must pass through solid fiberglass. Any air bubbles in the fiberglass or the epoxy will reduce or eliminate the sonar signals. Transducer location (high speed) Shoot-thru-hull transducer locations for...
- Page 16 If you can't get an acceptable bottom signal, try turning up the sensitivity by three or five keystrokes and then move the transducer around once more. If you find a spot that works, mark it and move on to step 4. If you have to turn up sensitivity by more than five keystrokes to get a good signal, the transducer should be mounted on the outside of the hull.
- Page 17 100 grit sandpaper. The sanded hull area should be about 1-1/2 times the diameter of the transducer. The surface of the hull must be flat so the entire transducer face is in contact with the hull prior to bonding. After sanding, clean the hull and transducer with rubbing alcohol to remove any sanding debris.

the transducer should be parallel with the hull, with a minimum amount of epoxy between the hull and transducer. 4. Apply a weight, such as a brick, to hold the transducer in place while the epoxy cures. Be careful not to bump the transducer while the epoxy is wet. -

To unit Power and transducer connections for the X51 Pro sonar unit (direct battery connection shown). CAUTION: Do not use this product without a 3-amp fuse wired into the power cable! Failure to use a 3-amp fuse will void your warranty. This unit has reverse polarity protection. - Page 20 Bracket Installation Mount the unit in any convenient location, provided there is clearance when it’s tilted for the best viewing angle. You should also make sure there is enough room behind the unit to attach the power/transducer cable. (See the following drawings, which show the dimensions of a mounted X51 Pro.) Holes in the bracket’s base allow wood screw or through-bolt mounting.
