User manual EAGLE FISHSTRIKE HS-WS-50D OPERATION INSTRUCTION

[. . . ] If it isn't done properly, the sonar can't perform to its potential. 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. [. . . ] Mount the transducer at least one foot from the engine's lower unit. This will prevent air bubbles from the transducer interfering with the propeller. 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 4 POOR LOCATION GOOD LOCATION POOR ANGLE GOOD LOCATION 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. Once you determine the best location for the transducer, hold the bracket against the transom. The transducer should be roughly parallel to the ground. The bottom of the hull should be about halfway between the centerline of the transducer and its bottom. (See the illustration below. ) Mark the transom in the center of each slot in the transducer bracket. Now drill one hole in the center of each slot. Use #12 stainless steel screws (not included) to loosely attach the brackets to the transom. Adjust the transducer and bracket so that the front of the transducer is slightly lower than the back. See the section on fish arches in this manual for proper transducer angles. Clamp the transducer cable to the transom close to the transducer. This will prevent the transducer from entering the boat should it be knocked off at high speed. Route the transducer cable to the sonar unit. Keep the transducer cable away from other wiring on the boat, if possible. Electrical noise from engine wiring or bilge pumps can be picked up on the transducer cable. This can show up as unwanted interference on the sonar display. FLAT-BOTTOM HULL DEEP-"VEE" HULL 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 over 35 mph. The transducer should be mounted as far below the hull as possible on these boats. [. . . ] If the supplied cable is not long enough to reach the battery, splice #18 gauge insulated wire to it. You can attach the power cable to an accessory or power buss, however, you may have problems with electrical interference. Make certain to attach the in-line fuse holder to the positive lead as close to the battery or terminal strip as possible. This will protect both the unit and the power cable in the event of a short.
