1 – Introduction About the FishFinder L365 The FishFinder L365 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 L365 can handle man

The transom-mount style, used most often, and in-hull types are shown in Fig. 2-1. Besides measuring water depth, the transducers also have two other sensors: a paddle wheel which detects the speed of the boa

Use a trolling motor transducer if – . . . you want to attach the transducer to a trolling motor. (Not recom- mended for deep-water operations.) Use a Sidelooker transducer if – . . . you need a way of searching for fish 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 installat

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 10" (254 mm) measured from the bottom of the transom. If considering the Sidelooker option, look for a mounting location where the Sidelooker array will not be blocked by the engine housing or other mounted hardware. If the boat will be

6. Attach the bracket to the hull using the panhead screws with flat washers. Before you tighten the screws, apply a good-quality marine sealant to the pilot holes. This will protect the hull from water penetra- tion. Do not tighten the screws completely yet. 7. Move the bracket up or down so that the leading edge of the trans- ducer has the clearance shown in Fig. 2-5. 8. Once the bracket is in the correct position, you can tighten the screws.

Installation Notes – Thru-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. Earlier we listed three general rules for placing transducers. All of these rules apply when you are mounting a thru-hull transducer. Here are some other rules for selecting the best mounting location: For planing hulls – I

fairing block must be able to resist the drag of the water against the hull, and must also be completely waterproof. 6. If the hull of the boat has a core-type hull, you will need to follow some special mounting procedures. The core material must be protected from any water which may leak from the inside of the boat. (If the core material is allowed to remain wet, it may rot and weaken the hull.) 7. When working with the transducer, support it by holding the body of the unit or the rings. Do n

Installation Notes – Trolling Motor Transducer Both Downlooker and Sidelooker transducers may be installed on a trolling motor. See Fig. 2-8. Fig. 2-8 Installing the Sidelooker Transducer on a Trolling Motor Detailed instructions for these installations will be included with the transducer(s). The Downlooker transducer is mounted on the horizontal gear case of the motor. The Sidelooker transducer is attached to the vertical support tube. These installations are simple, but it is important to
