INTRODUCTION

The X-75 and X-85 are the latest members of the Lowrance family that combines a high performance sonar with a wide, high definition screen. Using menu features and “soft-key” operation, these units are also easy to use. The wide screen shows the underwater world with high resolution and detail. The display and keyboard are also lighted for night operation. They have digital boat speed, surface water temperature, and distance travelled (log) screens. (Requires optional ST-TBK speed/temperature sensor for both speed and temperature screens.)

The optional SAM-50HPD gives these units 50 kHz capability.The 3000 watt transmitter in the SAM-50HPD plus the low frequency gives the units far more depth penetration. This, along with the wider cone angle transducers, makes 50 kHz operation ideal for ocean and Great Lakes use.

INSTALLATION

MOUNTING

Install the unit in any convenient location, provided there is clearance behind the unit when it is tilted for the best viewing angle. Holes in the bracket base allow wood screw or through-bolt mounting. You may need to place a piece of plywood on the back of thin fiberglass panels to secure the mounting hardware. Make certain there is enough room behind the unit to attach the power and transducer cables.

The gimbal bracket will also accept the GBSA-1 swivel bracket adapter that lets you rotate the unit a full 360°.

The smallest hole that allows one power or transducer connector to pass through is 3/4". After the hole is drilled, push the transducer connector up through the hole first, then drop the power cable down through it.

After the cables have been routed, fill the hole with a good marine sealing compound. Offset the bracket to cover the hole. Route the power cable through the slot. Break out one of the holes in the back of the bracket for the transducer cable.

FRONT

POWER CONNECTIONS

The unit works from a twelve-volt battery system. For the best results, attach the power cable directly to the battery. You can attach the power cable to an accessory or power buss, however you may have problems with electrical interference. Therefore, it’s safer to go ahead and attach the power cable directly to the battery. If the cable is not long enough, splice #18 gauge wire onto it. The power cable has two wires, red and black. Red is the positive lead, black is negative or ground. Make certain to attach the in-line fuse holder to the red lead as close to the power source as possible.

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. It uses a 3-amp fuse.

IMPORTANT!

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.

If you’re installing a speed/temperature sensor, read it's mounting instructions. Route the sensor’s cable to the power cable and plug it into the connector marked “SPEED/TEMP CABLE”

SPEED/TEMPERATURE SENSORS

This unit accepts up to three temperature sensors which can monitor surface water, live well, air, and virtually any other temperature. You do need to be careful when purchasing the temperature sensors, however. Each temperature sensor has its own "address". The sensors are labeled "Water", "T-2" (or Temp-2), and "T-3" (or Temp-3). If you want two (or more) temperature readings, you'll need to use the proper sensors. For example, you can't use two T-3 sensors. The sensors that will fit these units are:

TS-1BK

One sensor for "Water" temperature display.

TS-2BK

One sensor for "T-2" temperature display.

TS-3BK

One sensor for "T-3" temperature display.

TS-12BK

Two sensors for "Water" and "T-2" temperature displays.

ST-TBK

One speed sensor and one temperature sensor for

 

"Speed" and "Water" displays.

You can combine these sensors in many combinations. See the list on the following page for temperature and speed sensor combinations.

Sensor Chart

(Note: Do not use these sensors in any other combination.) ST-TBK = 1 speed sensor and 1 temperature display

ST-TBK + TS-2BK = 2 temp sensors and one speed sensor

ST-TBK + TS-2BK + TS-3BK = 3 temp sensors and one speed sensor TS-1BK = 1 temperature sensor

TS-12BK = 2 temperature sensors or

TS-1BK + TS-2BK = 2 temperature sensors

TS-12BK + TS-3BK = 3 temperature sensors or

CONNECTORS

The diagram above shows the three connectors on the back of the sonar unit. Looking at the back of the unit, the 192 kHz transducer connector is at the far left. Plug the 192 kHz transducer in here. The center connector is for the power cable. The connector at the far right is for a serial cable that is included with the SAM-50HPD. This is the cable that allows the SAM to communicate with the sonar unit. See the SAM-50HPD's installation manual for more information.

Transducer Installation

Some of the models covered by this manual have a transom-mount transducer included. There two different transducers that could be packed with your unit. One is a 20° cone angle "Skimmer" transducer that can be mounted on the transom or epoxied inside certain boats to "shoot-thru" the hull. The other transducer is an 8° cone angle "Skimmer" transducer that is transom-mounted only.

The 8° transducer has a “kick-up” mounting bracket helps 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 in place without tools.

Read this manual carefully before attempting the installation. Determine which of the mounting positions is right for your boat. Use extreme care if mounting the transducer inside the hull, since once it is epoxied into position, the transducer usually cannot be removed. Remember, the transducer location is the most critical part of a sonar installation.

Location - General - All Transducers

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 will show on the sonar’s display in the form of random lines or dots whenever the boat is moving.

2.The transducer should be installed with it’s face pointing straight down, if possible.

3.If the transducer is mounted on the transom, make certain it doesn’t interfere with the trailer or hauling of the boat. Also, don’t mount it closer than approximately one foot from the engine’s lower unit. This will prevent cavitation interference with the propeller. Typically, the transducer should be mounted as deep in the water as possible. This increases the chance that it will be in the water in high speed and reduces the possiblity of air bubble interference.

4.If possible, route the transducer cable away from other wiring on the boat. Electrical noise from engine wiring, bilge pumps, and areators can be displayed on the sonar’s screen. Use caution when routing the transducer cable around these wires.

Shoot-thru-hull v.s. Transom Mounting

(20° Transducer Only)

Typically, shoot-thru-hull installations give excellent high speed operation and good to excellent depth capability. There is no possibility of damage from floating objects. It can't be knocked off when docking or loading on the trailer.

However, the shoot-thru-hull installation does have its drawbacks. One, 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 layup and construction. Two, the angle of the transducer cannot be adjusted for the best fish arches. This can be a problem on some hulls that sit with the bow high when at rest or at slow trolling speeds. Follow the procedure listed in the shoot-thru-hull installation section in this manual to determine if you can satisfactorily shoot through the hull.

Transducer Assembly and Mounting - 20° Transducer Only

The best way to install this transducer is to loosely assemble all of the parts first, place the transducer’s bracket against the transom and see if you can move the transducer so that it’s parallel with the ground.

1.Press the two small plastic ratchets into the sides of the metal bracket as shown below. Notice 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 fourteen (14) degree transom. Most outboard and stern-drive transoms have a fourteen degree angle.

DOT

2.Slide the transducer between the two ratchets. Temporally 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 to the ground. If it does, then the “A” position is correct for your hull. 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. Again, check to see if you can move the transducer so it’s parallel with the ground. If you can, then go to step 3. If it doesn’t, repeat step 2, but use a different letter until you can place the transducer on the transom correctly.

RATCHETS

3.Once you determine the correct position for the ratchets, assemble the transducer as shown at left. Don't tighten the lock nut at this time.

4.Hold the transducer and bracket assembly against the transom. The transducer should be roughly parallel to the ground.The bottom of the transducer bracket should be in line with the bottom of the hull. Don't let the bracket extend below the hull! Mark the center of the slots for the mounting holes. Drill two 5/32" holes in the marked locations for the #10 screws supplied with the transducer.

5.Remove the transducer from the bracket and re-assemble it with the cable passing through the bracket over the bolt as shown above. Attach the transducer to the transom. Slide the transducer up or down until it’s aligned properly on the transom as shown above. Tighten the bracket’s mounting screws. Adjust the transducer so that it’s parallel to the ground and tighten the lock nut until it touches the flat washer, then add 1/4 turn. Don’t over tighten the lock nut! If you do, the transducer won’t “kick-up” if it strikes an object in the water.

6.Route the transducer cable to the sonar unit. Make certain to leave some slack inthe cable at the transducer as shown above. If possible, route the transducer cable away from other wiring on the boat. Electrical noise from the engine’s wiring, bilge pumps, VHF radio wires and cables, and aerators can be picked up by the sonar. Use caution when routing the transducer cable around these wires.

IMPORTANT!

Clamp the transducer cable to the transom close to the transducer. This can prevent the transducer from entering the boat if it is knocked off at high speed.

7.Make a test run to determine the results. If the bottom is lost at high speed, or if noise appears on the display, try sliding the transducer bracket down. This puts the transducer deeper into the water, hopefully below the turbulence causing the noise. Don't allow the transducer bracket to go below the bottom of the hull!

SHOOT-THRU-HULL

(20° Transducer Only)

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. For example, some manufacturers use a layer of fiberglass, then a core of balsa wood, finishing with an outer layer of fiberglass. Removing the inner layer of fiberglass and the balsa wood core exposes the outer layer of fiberglass. The transducer can then be epoxied directly to the outer layer of fiberglass. After the epoxy cures, 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.

To choose the proper location for thru-hull mounting, anchor the boat in 60 feet of water. Add a little water to the sump of the boat. Plug the

transducer into the sonar unit, turn it on, then hold the transducer over the side of the boat. Adjust the sensitivity and range controls until a second bottom echo is seen on the display. (you will need to turn both automatic and ASP off.) 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. Observe the sonar signal to see if there is a noticeable decrease in sensitivity. The second bottom signal may disappear and the bottom signal may decrease in intensity. Move the transducer around to find the best location. If the sensitivity control has to be increased greatly to compensate, then the transducer should be mounted on the outside of the hull. If not, then mark the location that shot through the hull the best and follow the instructions on the next pages for a shoot-thru-hull mounting.

Shoot-thru-hull Installation

(20° Transducer Only)

1. Make certain the area is clean, dry, and free of oil or grease, then sand both the inside surface of the hull and the face of the transducer with 100 grit sandpaper. The surface of the hull must be flat so the entire transducer face is in contact with the hull prior to bonding.

SPREAD EPOXY HERE

SAND THIS SURFACE

2. Follow the instructions on the epoxy package and mix it thoroughly. Do not mix it too fast, as 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. Place the transducer into the epoxy, twisting and turning it to force any air bubbles out from under the transducer face. The face of the transducer should be parallel with the hull, with a minimum amount of epoxy between the hull and transducer. After the epoxy dries, route the cable to the sonar unit.

TRANSDUCER INSTALLATION - 8° Transducer Only

The 8° transducer is designed for transom mount only. It can be installed on any outboard or stern-drive powered boat. Do not use this transducers on an inboard powered boat.

Please read these instructions carefully before installing your transducer. The transducer mounting location is the most critical part of a sonar installation. If it isn’t done properly, the sonar can’t perform to its potential.

ASSEMBLY

1.Locate the four ratchets in the transducer's hardware package. Note there are letters engraved into one side of each ratchet. These are for the coarse angle adjustment. A standard transom angle is 14 degrees. By aligning a letter on the ratchet to the alignment mark on the the transducer bracket, the correct transducer angle can be attained. Once you've determined the correct angle, press one ratchet on each side of the transducer and one ratchet on each transducer bracket as shown below.
