Installation Overview

Following are instructions for the installation of this accessory. Before you start installation, we encourage you to read these instructions carefully in order to get the full benefit from your Humminbird® accessory.

If you find that any items are missing from your installation kit, call our Customer Resource Center at 1-800-633-1468 or visit our website at www.humminbird.com.

In addition to the hardware supplied with your transducer, you will need a powered hand drill and various drill bits, Phillips and flat head screwdrivers, a ruler or measuring tape, pen or pencil, and marine-grade silicone sealant.

Installation

There are a number of ways to install a transducer on your boat. The transom mount installation provides the least loss of signal since the transducer is mounted outside the boat hull. This installation also allows adjustment of both running angle and depth after the transducer is mounted, which enables you to tune the installation for best results. Also, the mounting hardware is designed to pivot the transducer body out of the way should the boat strike debris in the water, or when trailering.

Locating the Transducer Mounting Position

Turbulence: You must first determine the best location on the transom to install the transducer. It is very important to locate the transducer in an area which is relatively free of turbulent water. Consider the following to find the best location with the least amount of turbulence:

• As the boat moves through the water, turbulence is generated by the weight of the boat and the thrust of the propeller(s) - either clockwise or counter-clockwise. This turbulent water is normally confined to areas immediately aft of ribs, strakes or rows of rivets on the bottom of the boat, and in the immediate area of the propeller(s). Clockwise propellers create more turbulence on the port side. On outboard or inboard/outboard boats, it is best to locate the transducer at least 15" (380 mm) to the side of the propeller(s).

• The best way to locate turbulence-free water is to view the transom while the boat is moving. This method is recommended if maximum high-speed operation is a high priority. If this is not possible, select a location on the transom where the hull forward of this location is smooth, flat and free of protrusions or ribs.

• On boats with stepped hulls, it may be possible to mount the transducer on the step. Do not mount the transducer on the transom behind a step to avoid popping the transducer out of the water at higher speeds; the transducer must remain in the water for the control head to maintain the sonar signal.

• If the transom is behind the propeller(s), it may be impossible to find an area clear from turbulence, and a different mounting technique or transducer type should be considered, such as an Inside the Hull Transducer.

Deadrise: Another consideration is the angle of deadrise. The transducer, when mounted, should point straight down. The design of the transducer will allow a deadrise of 15 degrees while remaining pointed straight down. If the deadrise is greater than 15 degrees it will be necessary to angle the transducer slightly. While this does not significantly degrade performance, you must keep in mind that the area you are viewing on your fishfinder screen may be somewhat to one side of the boat.

Mounting the Bracket

Mount the bracket, using the mounting template provided as a guide. This template serves two purposes: it allows you to mark where the mounting holes should be drilled, and it provides a way to make sure that the deadrise of the transom falls within the allowable limits.

1. Cut out the transducer mounting template from this sheet. Match the mounting bracket screw slots to the template screw slots.

2. Hold the template on the transom of the boat in the location you have selected. Align the template vertically, making sure that the lower edge of the transom on either side of the template falls within the horizontal lines on the template.

NOTE: If your propeller moves clockwise as the boat moves forward, mount the transducer on the starboard side, and use the bottom left corner of the template. If your propeller moves counter-clockwise as the boat moves forward, mount the transducer on the port side, and use the bottom right corner of the template.

3. Continue to hold the template on the transom of the boat, and use a pencil or punch to mark where to drill the mounting holes shown on the template.

4. Using a 5/32” (4.0 mm) bit, drill the three holes only to a depth of approximately 1” (25 mm).

NOTE: On fiberglass hulls, it is best to use progressively larger drill bits to reduce the chance of chipping or flaking the outer coating.

5. Use a marine-grade silicone sealant to fill the drilled holes, especially if the holes penetrated the transom wall.

6. Align the metal mounting bracket with the mounting holes. The center slot of your mounting bracket should be above the two outer slots (this bracket and all other hardware supplied is top quality stainless steel for maximum strength and corrosion protection). Insert the three 1” (25.0 mm) flat head wood screws into the drilled holes, but do not completely tighten.

Assembling the Transducer

Attach the pivot to the transducer using the hardware provided.

1. Attach the pivot to the transducer body as shown in the illustration using the two 1/4"–20 x 5/8" (16 mm) machine screws, toothed washers, and square nuts. The toothed washers must fit on the inside of the transducer ears, between the pivot and the ears. The square nuts will be prevented from rotating by the pocket in the back of the pivot.

NOTE: An Allen wrench is provided which fits all of the 1/4”–20 screws, but do not fully tighten the screws at this time.

Attaching the Transducer to the Bracket

1. Slide the assembled transducer into the metal bracket from the bottom, aligning the large hole at the top of the bracket with the hole in the pivot.
