Installation Preparation

Read the instructions in this transducer guide completely to understand the mounting guidelines before starting the installation.

NOTE: This transducer requires drilling a hole in the hull of the boat; therefore, installation should be performed by a qualified marine technician.

Review your boat manufacturer’s owner’s manual for recommended transducer installation locations and cable routing methods. You will also need your hull’s deadrise angle.
Read and understand your boat’s warranty before starting this installation.
Test Route the Cable Installation: Test route the transducer cable connector to the control head and confirm that the cable is long enough for the planned route. Your boat may have a pre-existing wiring channel or conduit that you can use for the transducer cable. See section 6: Route the Cable for requirements. Your installation may require extension cables and hardware for routing the cable to the control head.
Visit our Web site at humminbird.com for additional information and resources for transducer installations. Also, visit youtube.com/humminbirdtv for informational videos.
Confirm your boat is level for the installation.

Supplies: In addition to the supplied hardware, you will need a drill, a small drill bit for the pilot hole, a 1 1/8″ (2.8 cm) hole saw, a level, a Phillips- head screwdriver, and marine-grade silicone sealant.

Installation Overview

NOTE : This type of transducer installation is not recommended for trailerable boats.

Test the Transducer Prior to Installation
Prior to installation, test the transducer to make sure that no damage occurred during shipping

  1. Confirm the control head is connected to power. See your control head installation guide for instructions.

  2. Connect the transducer cable connector to the transducer (or sonar) port on the control head. See section 7: Connect the Cable.

  3. Power On : Press the POWER key to turn on the control head. If the transducer is detected, the control head will start Normal mode.

  4. Select a 2D Sonar View to display on-screen.
    NOTE : See your control head operations manual for more information.

  5. Lower the transducer into the water. (The transducer must be fully submerged because the sonar signal cannot pass through air and air pinging can damage the transducer).
    If the bottom is visible on-screen with a digital depth readout, the transducer is working properly.

  6. After confirming proper operation, power off the control head, and unplug the transducer cable connector from the control head.

Determine the Transducer Mounting Position

The Side Imaging transducer has specific mounting requirements. Consider the following to find the best mounting location for the transducer.

WARNING! Do NOT install the transducer in line with the engine intake.

Determining the Transducer Mounting Position

  1. The best mounting location for the transducer is aft midship, as close to the centerline of the boat as possible.

  2. Make sure nothing is in front, behind, or to the side of the transducer that is closer than 12″ (30.5 cm). The transducer should be mounted forward of the propellers on inboard boats, and separated adequately from other transducers, strakes, rivet lines, or other protrusions on the boat.

  3. Deadrise : The transducer, when mounted, must be parallel with the waterline. If the selected mounting location has a hull deadrise of 2 degrees or greater, the included leveling block should be used to level the transducer housing and direct the sonar signal straight down.

  4. The Side Imaging transducer must NOT have anything obstructing the ‘view’ of the side looking beams. For example, nothing can be in the line of sight of these beams (not a hull, motor, or other transducer, etc.)
    NOTE : Side Imaging sonar is best performed at boat speeds from 2 to 6 mph, and it is not recommended for high-speed operation (as gaps between strips of information can appear). However, the transducer can support traditional 2D sonar and Down Imaging® sonar at higher speeds. Rough seas and air bubbles can also affect the reading of the Side Imaging transducer.

  5. Inside the Boat : There must be room to access the mounting location for installation and cable routing. If you need to use the leveling block, make sure the inside surface of the hull is smooth enough to seat the leveling block securely.

RECOMMENDED:
In the illustration, the transducer is close enough to the centerline so that the hull will not interfere with the Side Imaging beams.

NOT RECOMMENDED:
In the illustration, the transducer is too far from the centerline, and the hull is blocking the Side Imaging beams.

Installation Scenarios for Consideration:

  • Flat Hull, One Transducer: Locate a flat area on the bottom of the hull, forward of where the propeller shaft comes out of the hull. Make sure there is nothing lower than this location to the right or left.
  • V-shaped Hull, Two Transducers: Install two thru-hull transducers, one on each side of the V. Connect the transducers with a Y-Cable.
  • Two Back Engines, Two Transducers: Install two thruhull transducers outboard from the dual engines. Connect the transducers with a Y-Cable.

NOTE : Installations with two transducers require a Y-Cable (or Splitter Cable), which vary based on the control head model. To purchase a cable, visit our Web site at humminbird.com.

Installation

Perform the procedures in the following sections to install the transducer on your boat.

Drill the Hole and Prepare the Leveling Block
Follow the instructions below for the installation type that matches your hull and deadrise

CAUTION! Use only the leveling block included with this transducer. Do NOT use a wooden leveling block, as any swelling of the wood might cause the plastic on the transducer to shatter.

NOTE : A separately purchased fairing block can also be used to create a hydrodynamic waterflow around the transducer body. The design and fabrication of this block varies greatly with different hull shapes; therefore, it should be customized by a qualified marine technician

Standard Installation (Flat Hull, Deadrise less than 2°):
For an installation that needs to minimize the impact of a small obstruction, but where the deadrise is less than 1 to 2 degrees, use the included leveling block (uncut), and mount it outside the hull.

  1. From the outside of the hull, drill a small pilot hole (smaller than the centering bit of your drill bit or hole saw), at the mounting location you selected in section 2. Drill the hole perpendicular to the hull.
  2. Use the pilot hole (from the outside of the hull) to drill a 1 1/8″ (2.8 cm) hole that is sized to fit the threaded stem of the transducer. Drill the hole perpendicular to the hull.
  3. Thoroughly clean and deburr the drilled hole and clean the outside of the hull.
  4. The leveling block will be installed (uncut) on the outside of the hull. Proceed to Section 4: Attach the Transducer.

Alternate Installation (Deadrise more than 2°):
For an installation where the deadrise is more than 2 degrees, use the included leveling block, cut at the appropriate angle, to compensate for the deadrise.

  1. From the outside of the hull, drill a small pilot hole (smaller than the centering bit of your drill bit or hole saw), at the mounting location you selected in section 2. Drill the hole perpendicular to the waterline.
  2. Use the pilot hole (from the outside of the hull) to drill a 1 1/8″ (2.8 cm) hole that is sized to fit the threaded stem of the transducer. Drill the hole perpendicular to the waterline.
  3. Thoroughly clean and deburr the drilled hole and clean the outside of the hull.
  4. If the hull angle is greater than 2 degrees, cut the included leveling block and use both pieces to level the transducer. The block should be cut to match the angle of the deadrise of the hull.
  5. Cut the leveling block into two equal pieces: one which mounts outside the hull and is shaped to match the profile of the transducer, and one which mounts inside the hull and provides a level surface for the fasteners.
  6. The thinnest wall of the outside leveling block must be at least 1/8″ (3 mm).
  7. The leveling block included with your transducer can accommodate a maximum deadrise angle of 25 degrees.
  8. The leveling block will be installed (cut) on the inside and outside of the hull. Proceed to Section 4: Attach the Transducer

Attach the Transducer

  1. Feed the transducer cable through the drilled hole, then temporarily install the transducer to check the fit.
  2. Apply a generous amount of marine-grade silicone sealant or slow-curing epoxy inside the drilled hole and along the mating surfaces of the transducer housing and leveling block.
  3. Proceed to the instructions that correspond with your installation type (control head model) and transducer orientation.

SOLIX Series

  1. Make sure the rounded end of the transducer is facing the bow, pointing forward, and parallel to the centerline.
  2. Insert the transducer into the drilled hole from outside the boat with the leveling block(s) installed according to your installation type.
  3. Hold the shroud horizontally with the inside teeth facing up. Thread the cable connector through the shroud. See the illustrations below.
  4. Fit the split nut pieces to each other with the cable in the center. The ridged side of the split nut should face down.
  5. Slide the split nut into the shroud so that the assembly is flat. Install the two screws into the shroud holes to secure the assembly. Hand tighten only.

HELIX Series

  1. Make sure the rounded end of the transducer is facing the bow, pointing forward, and parallel to the centerline.
  2. Insert the transducer into the drilled hole from outside the boat with the leveling block(s) installed according to your installation type, then install the nut onto the threaded stem from inside the boat.

Finish the Installation

  1. Hand tighten the split nut onto the threaded transducer stem ONLY until the assembly is firmly seated, then tighten NO MORE than 1/8 of a turn extra.
    WARNING! To avoid damage, do not overtighten the nut.
    NOTE : This type of transducer is directional in nature and must be aligned with the front of the boat (the direction of travel) and parallel to the centerline. Failure to align the transducer properly will result in incorrect bottom readings and incorrect fish locations. (See the illustrations for orientation).

  2. Remove the excess adhesive sealant from the outside of the hull to ensure smooth water flowB over the transducer.

Route the Cable

The transducer cable must be routed to the point where the control head is mounted. Your boat may have a pre-existing wiring channel or conduit that you can use for the routing.

Route and secure the transducer cable connector to the control head, avoiding areas where it may be damaged or interfere with normal boating operations.

CAUTION! Do not cut or shorten the transducer cable, and try not to damage the cable insulation. Route the cable as far as possible from any VHF radio antenna cables or tachometer cables to reduce the possibility of interference. If the cable is too short, extension cables are available to extend the transducer cable up to a total of 50′ (15 m). For assistance, contact Humminbird Technical Support for more information.

CAUTION! Do NOT mount the cables where the connectors could be submerged in water or flooded. If cables are installed in a splash-prone area, it may be helpful to apply dielectric grease to the inside of the connectors to prevent corrosion. Dielectric grease can be purchased separately from a general hardware or automotive store

Connect the Cable

  1. Connect the transducer cable connector to the sonar port on the control head or cable tray (if applicable). See your control head installation guide for details. The ports are labeled and the connectors are keyed to prevent incorrect installation, so do not force the connector into the wrong port.
  2. The control head will automatically detect the transducer and configure it with the control head. For additional configuration information, see your control head operations manual.
Maintenance

If your transducer remains in the water for long periods of time, slush, algae and other marine growth can reduce the effectiveness of the transducer. Periodically clean the face of the transducer with a mild, marine-safe and plastic-safe soap or solution.If your transducer remains out of the water for a long period of time, it may take some time to wet the transducer after it is returned to the water. Small air bubbles can cling to the surface of the transducer and interfere with proper operation. These bubbles will dissipate with time, or you may wipe the face of the transducer with your fingers after the transducer is in the water.

Important Notices

WARNING! The transducer must be fully submerged in water during operation because the sonar signal cannot pass through air. Air pinging can damage the transducer.
