1 – Introduction About the FishFinder L265 The FishFinder L265 is a system that uses sound waves (“sonar”) to detect fish and show the bottom of a lake or sea. 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 man

System Components The FishFinder L265 consists of a compact display unit connected to a transducer. The transducer is attached to the boat and extends into the water. Standard Equipment When you unpack your FishFinder L265, you should find the following standard equipment in the carton. If any items are missing, please notify your Raymarine dealer immediately, or contact the Customer Service Department at Raymarine at 1-800-539-5539, ext. 2333. Please provide the serial number of the FishFind

2 – Installation The installation process has four parts: Mounting the transducer Mounting the display unit Connecting the cables for the transducer and power supply Calibrating the display unit About the Transducer Several different kinds of transducers can be used with this unit. 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

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 recom- mended for

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

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 tr

5. Remove the bracket. See Fig. 2-6. The screws in the outer slots should be placed about 1/4" (6 mm) up from the bottom of each slot. The screw in the center slot should be placed 1/4” (6 mm) down from the top. (This will allow you to adjust the bracket up or down a bit.) Drill pilot holes 3/4" (19.1 mm) deep. Use a 9/64" (3.6 mm) drill bit. To prevent drilling too deeply, wrap masking tape around the drill bit about 7/8" (22 mm) from the tip. Drill in only as far as the tape marker. If you

Fig. 2-7 Installing the Sidelooker Transducer Installation Notes – Thru-Hull Transducer or Low-Profile Transducer The installation process for these two types is almost the same. Detailed instructions for this installation will be included with the transducer. In this section, we will note just a few important points. 1. Earlier we listed three general rules for placing transducers. All of these rules apply when you are mounting a thru-hull or low profile transducer. Here are some other rules

2. Choose a location where you can easily reach the transducer from inside the boat. This will allow you to service the unit. Allow at least 6" (152 mm) of headroom above the transducer. 3. When choosing a mounting location, drill a small pilot hole (1/8" or 3.2 mm) from the inside of the hull. Before you drill the hole, be sure you will be able to reach the large nut on the top of the unit, and that there will be enough clearance for the cable. If there is a strake or other feature on the h

Installation Notes – In-Hull Transducer Detailed instructions for this installation will be included with the trans- ducer. In this section, we will note just a few important points. 1. Choose the best mounting location: For outboard powerboats – Install as far aft as possible For inboard/outboard powerboats – Install close to the engine(s) For inboard powerboats – Install forward of the propeller(s) and shaft(s) For sailboats – Install near the centerline of the hull and forward of the leading
