The system includes a transducer and a display unit, connected by a cable. The transducer sends high-frequency sound waves down into the water. These sounds strike fish, the bottom, or other objects in the water, and return as echoes. The FishFinder then interprets these echoes and presents a display. The FishFinder L265 can handle many different jobs: · detect the presence of fish below the boat · trigger an alarm when fish are found · measure the depth of the water · set alarms for minimum and maximum depth · show the shape of the bottom · determine whether the seabed is hard or soft We are sure you will find the FishFinder L265 to be one of the most useful devices on your boat.

The transom-mount style, used most often, and in-hull types are shown in Fig. 2-1. All of these transducers measure the water depth. An optional transducer, the Sidelooker, detects objects by looking out to the sides of the boat. Since the transducer is very important to the operation of the FishFinder, it is vital that the transducer be mounted correctly. The transducer will give the most reliable readings if it looks into water which is smooth and undisturbed. If you place the transducer so bubbles or turbulence flow across the face of the unit, the system may give inaccurate readings. There are three important rules when mounting any type of transducer: · The transducer should be continuously covered by water when the boat is moving. (If the transducer is mounted near the side of the boat, it may be exposed when the boat is turning.) The transducer should be placed where turbulence or bubbles will not pass directly over the face of the unit. Don't place the transducer behind any running strakes, intakes, or thru-hull fittings which create turbulence. The transducer should be mounted where it will not be affected by the wash from the propeller(s). · · Selecting the Correct Type of Transducer Before you begin the installation, double-check to be sure you have the correct type of transducer. Each kind of transducer is designed for a 4 Installation M78990 Transom-mount transducer M78921 Thru-hull transducer M99-141 Fairing for thru-hull transducer M78922 Low profile transducer M78946 In-hull transducer M78930 Sidelooker transducer M78928 Sidelooker transducer for trolling motor Fig. 2-1 Transducer Types particular type of use. In this manual we will include detailed mounting instructions for the transom-mount transducer. We will also include some general information on the other types. For detailed information on these other transducers, see the instructions which are packaged with the unit. Use a transom-mount transducer if ­ . . . your boat has an outboard or inboard-outboard engine(s), and if you're planning to use the Sidelooker option. This type of transducer must be mounted ahead of or beside the propeller(s). Do not use this type of transducer for a boat with a straight-shaft inboard engine. Use a thru-hull transducer if ­ . . . your boat has a straight-shaft inboard engine. This type of transducer is installed in a hole drilled through the hull. Installation 5 Use a low-profile transducer if ­ . . . you want minimum water resistance on a high-performance boat or sailboat. The bottom of the boat must be flat, or have a deadrise angle of no more than 10°. Use an in-hull transducer if ­ . . . you have a high-speed boat or if, for some reason, you cannot use a transom-mount or thru-hull transducer. The hull may be no more than 1" thick. Use a trolling motor transducer if ­ . . . you want to attach the transducer to a trolling motor. (Not recommended for deep-water operations.) Use a Sidelooker transducer ­ . . . for searching for fish or structure on either side of the boat. This type of transducer is attached to the bracket of the transom-mount transducer, or to the shaft of the trolling motor. Assembling the Transducer Bracket Fit together the two parts of the transducer bracket as shown in Fig. 2-2. When the installation is complete, the parts snap together as shown. LIKE THIS! Attach the two parts NOT THIS! Bracket is installed upside down Lower the transducer and snap in the release clip Fig. 2-2 Assembling the Transducer Bracket 6 Installation Fig. 2-3 Transducer Mounted on Transom Allow a clearance of at least 10 inches (254 mm) 10" (254 mm) Transducer in released position Fig. 2-4 Transducer Bracket, Side View Positioning the Transom-Mount Transducer Begin by finding the best location for the mounting bracket. Here are the rules: · If your boat has one propeller (outboard or inboard-outboard), mount the transducer about 18" (455 mm) to the side of the centerline of the boat. See Fig. 2-3. Choose the side that is on the downstroke of the propeller. (This is usually the starboard side of the boat.) This will reduce any interference caused by air bubbles. Installation 7 Average transom angle­ no wedge necessary Vertical transom ­ place wedge this way Sloping transom­ place wedge this way 2 to 5 2 to 5 2 to 5 For fiberglass hull ­ 1/8" to 1/4" (3.2 to 6 mm) For aluminum hull ­ 1/4" to 3/8" (6 to 9 mm) No! No! No! The bow of the transducer is above the bottom of the transom, creating cavitation. Rivets on the hull are creating bubbles. Lower the transducer a bit. The rear of the transducer is too high, creating cavitation. Fig. 2-5 Correct Mounting Position Insert screws 1 and 3 1/4" from the bottom of slots, and screw 2 1/4" from the top of the slot to allow room for adjustment. 1 2 3 Correct alignment If screws are inserted this way, it won't be possible to make the height adjustment. Incorrect alignment Fig. 2-6 Mounting the TransomMount Transducer 8 Installation · · · · · · If the propeller can be turned to steer the boat, allow at least 2" (50 mm) beyond the swing radius of the propeller. This will prevent the propeller from damaging the transducer when it is turned. After installation, check the clearance by turning the wheel so the propeller swings toward the transducer. There should always be a 2" (50 mm) clearance. If your boat has twin propellers (outboard or inboard-outboard), place the transducer near the centerline of the boat. Do not mount the transducer behind any hull fittings, intakes, or other parts which extend from the hull. These may cause turbulence or air bubbles. The bracket has a quick-release mechanism. This may reduce damage by allowing the transducer to flip up if it hits any debris or the bottom. See Fig. 2-4. Allow enough clearance above the transducer so that it can swing upward completely. This is about ...
