Maintenance
If your boat remains in the water for long periods of time, algae and other
marine growth can reduce the effectiveness of the transducer. Periodically
clean the face of the transducer with hot water.
If your boat 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.

Overview
Before you start installation, we encourage you to read these instructions carefully in order to get the full benefit from
your Humminbird® accessory.
Supplies: In addition to the hardware supplied with your transducer, you will need a drill, a small drill bit for a pilot
hole, a 1 1/8" hole saw, a level, marine-grade silicone sealant, a Phillips-head screwdriver, and dielectric grease.
Customer Service: To purchase additional equipment, or if you find that any items are missing from your installation
kit, visit our Web site at humminbird.com or call us at 1-800-633-1468.
Installation
Perform the procedures in the following sections to install the transducer on your boat.
1. Testing the Transducer Prior to Installation
Prior to installation, test the transducer to make sure that no damage occurred during shipping.
1. Connect the transducer cable connector to the control head port or black box sonar, depending on your system
configuration.
2. Power on the control head. Select a sonar view to display on-screen.
3. Hold the transducer in the water over the side of the boat to confirm proper operation. If the transducer is working
properly, you should be able to see the bottom on the control head display. The bottom image should be relatively
strong and there should be detailed structure on the display.
4. After confirming proper operation, power off the control head, and unplug the transducer cable connector from
the control head or black box sonar.
2. Locating the Transducer Mounting Position
Outside the boat, the best location for the transducer will be aft midship, as close to the centerline of the boat as
possible. The transducer should be mounted forward of the propellers on inboard boats, and separated adequately
from other transducers, strakes, rivet lines, or other protrusions. Make sure that there is nothing in front, behind, or to
the side of the transducer that is closer than 12".
WARNING! Do NOT install the transducer in line with the engine intake.
Inside the boat, there must be room to access the mounting location for installation and cable routing.
Deadrise: Another consideration is the angle of deadrise. The transducer, when mounted, should point straight down.
If the selected mounting location has a hull deadrise of 8 degrees or more, the included leveling block should be used
to level the transducer housing and direct the sonar signal straight down. If you need to use the leveling block, make
sure that the inside surface of the hull is smooth enough to seat the leveling block securely.
NOTE: If you cannot find a location that will work for your application, find a different transducer by visiting the FAQ
(Frequently Asked Questions) section of our Web site at humminbird.com or by calling Humminbird Customer Service
at 1-800-633-1468.
NOTE: This type of transducer installation is not recommended for trailerable boats.
NOTE: This transducer requires drilling a hole in the hull of the boat; therefore, installation should be performed by a
qualified marine technician.

Overview

This document describes the installation, operation, and maintenance of a Humminbird Plastic Thru-Hull Transducer.

Function Description

The Humminbird Plastic Thru-Hull Transducer is an accessory designed to provide sonar readings for marine vessels. It is intended for permanent installation through the hull of a boat, allowing for direct contact with the water for optimal sonar signal transmission and reception. The transducer works in conjunction with a Humminbird control head or black box sonar system to display bottom images and detect underwater structure and fish locations. Its directional nature requires precise alignment with the boat's direction of travel and parallel to the centerline to ensure accurate readings.

Important Technical Specifications

  • Hole Size: Requires a 1 1/8" (2.8 cm) hole drilled through the hull.
  • Leveling Block: Includes a leveling block to compensate for hull deadrise angles.
    • Standard Installation (Deadrise less than 8°): Uses an uncut leveling block, mounted either inside or outside the hull to minimize the impact of small obstructions.
    • Alternate Installation (Deadrise more than 8°): Uses a cut leveling block, with the thinnest wall of the outside block being at least 1/8" (3 mm). The leveling block can accommodate a maximum deadrise angle of 25 degrees.
  • Cable Length: The transducer cable should not be cut or shortened. Extension cables are available to extend the transducer cable up to a total of 50 feet.
  • Connector Types: Available with hexagon-shaped or round cable connectors. Round connectors feature a screw nut for secure attachment.
  • Power: Powered by the control head or black box sonar system.
  • Operating Mode: Automatically enters Normal operating mode when a functioning transducer is detected.
  • Transducer Type Selection: Supports various transducer types (e.g., Dual Beam, Quad Beam), depending on the model.

Usage Features

  • Pre-Installation Testing: The transducer can be tested prior to installation by connecting it to the control head and holding it in the water over the side of the boat to confirm proper operation and display of bottom images.
  • Mounting Location: The optimal mounting location is aft midship, as close to the centerline as possible, forward of propellers on inboard boats, and separated from other transducers, strakes, rivet lines, or protrusions by at least 12 inches to avoid turbulence.
  • Deadrise Compensation: The included leveling block allows for proper transducer alignment on hulls with varying deadrise angles, ensuring the sonar signal points straight down.
  • Installation Procedure: Involves drilling a pilot hole, then a larger 1 1/8" hole, cleaning and deburring the hole, applying marine-grade silicone sealant or slow-curing epoxy, inserting the transducer from outside the boat, and securing it with a nut (or split-nut assembly for round connectors) from inside the boat.
  • Cable Routing: The cable should be routed and secured, avoiding areas where it could be damaged or interfere with boating operations. It should be kept as far as possible from VHF radio antenna cables or tachometer cables to reduce interference.
  • System Configuration: After installation, the transducer type must be selected on the control head through the menu system (Sonar tab > Transducer Select or Connected Transducer) to ensure correct system operation. For PiranhaMAX models or those without the Transducer Select option, the transducer is automatically detected.
  • Safety Warnings:
    • Not to be used as a navigational aid to prevent collision, grounding, boat damage, or personal injury.
    • Disassembly and repair should only be performed by authorized service personnel to avoid voiding the warranty.
    • Do not overtighten the transducer nut to prevent damage.
    • Do not use a wooden leveling block, as swelling could shatter the plastic transducer.
    • Ensure proper orientation (narrow/thin end pointing forward) for accurate readings.
    • Avoid installing the transducer in line with the engine intake.
    • Do not mount cables where connectors could be submerged; apply dielectric grease in splash-prone areas to prevent corrosion.

Maintenance Features

  • Cleaning: Periodically clean the face of the transducer with a mild, marine-safe, and plastic-safe soap or solution to remove algae and marine growth, which can reduce effectiveness.
  • Re-wetting: If the boat has been out of the water for an extended period, small air bubbles may cling to the transducer surface. These will dissipate with time, or can be wiped away with fingers to restore proper operation.
  • Warranty: Covered by a 1-year limited warranty from the date of original retail purchase, covering defects in materials and workmanship. Repairs or replacements are provided free of charge at Humminbird's option. The warranty does not cover improper installation, use outside recommended instructions, damage from accidents or abnormal operation, or repairs/modifications by unauthorized entities. Proof of purchase (original receipt) is required for in-warranty service.
  • Service Policy: Humminbird aims to repair units within three business days of receipt at their factory. After the warranty period, a standard flat-rate service charge applies for repairs (excluding physical damage and missing parts), with a 90-day warranty on post-warranty repairs. Service is available in the United States only.
  • Returning for Service: To return a unit for service (in-warranty or out-of-warranty), contact Humminbird by phone or email to obtain a Repair Authorization Number. Include product model name, serial number, a brief problem description, and proof of purchase (for in-warranty). Ship the product freight prepaid, using an insured carrier with delivery confirmation. For out-of-warranty service, include payment (credit card or money order).
  • Environmental Compliance: Johnson Outdoors Marine Electronics, Inc. complies with environmental regulations, including the WEEE Directive (2002/96/EC) in the European Union, which requires responsible disposal and recycling of waste electrical and electronic equipment. Products are marked with the WEEE wheelie bin symbol, indicating they should not be disposed of with household refuse.
