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/

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 inte

LOWRANCE 192 kHz TRANSDUCER POWER TO SAM-50HPD (NOT INCLUDED) 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

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 "Skim- mer" transducer that is transom-mounted only. The 8° transducer has a “kick-up” mounting bracket helps prevent dam- age if the transducer

Shoot-thru-hull v.s. Transom Mounting (20° Transducer Only) Typically, shoot-thru-hull installations give excellent high speed opera- tion 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 installation

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 ratch- ets into the holes in the bracket with the letter “B” ali

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 w

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 success- ful 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 fiberglas

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.

F F E E D D C 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 transduc- ers on an inboard powered boat. Please read these instructions carefully before installing your trans- ducer. 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 ratch

INSTALLATION - Location 1. The transducer must be placed in a location that has a smooth flow of water at all times. Air bubbles created by the movement of the boat hull against the water interfere with the sonar signal. This causes “noise” or random marks to appear on the sonar’s display. You may need to care

POOR LOCATION GOOD LOCATION GOOD LOCATION POOR ANGLE 3. Don’t mount the transducer directly behind strakes or ribs on the bottom of the hull. Typically, a good location on aluminum boats is between the ribs closest to the engine. 4. Once you determine the best location for the transducer, hold the bracket against the transom. The transducer should be roughly paral- lel to the ground. The bottom of the hull should be about halfway between the centerline of the transducer and
