User manual EAGLE TRANSDUCERS HS WS 50D INSTALLATION INSTRUCTIONS

[. . . ] Follow the installation instructions for the power cable on the back of this manual. Please install the HS-NSPC transducer before wiring it's power cable. Please read these instructions carefully before installing your transducer. The transducer mounting location is the most critical part of a sonar installation. [. . . ] You may need to carefully view the water's path at the transom while the boat is moving to determine the best location for the transducer. Make certain the chosen location doesn't interfere with the boat's trailer. 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!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 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. 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. This will prevent the transducer from entering the boat should it be knocked off at high speed. 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. [. . . ] 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.
