Universal Sonar
Your trolling motor may be pre-installed with a Universal Sonar transducer system. Universal Sonar is a 2D sonar transducer with a
temperature sensor that is integrated into the lower unit of the trolling motor. It has an operating frequency of 83/200 kHz. Connecting
this transducer to a compatible fish finder gives you a 2D sonar view of what is happening directly below your trolling motor. The
integrated design protects the transducer from underwater hazards, and prevents tangles and damage to the transducer cables.
All Universal Sonar motors are equipped with an internal bonding wire, incorrect rigging will cause sonar interference and can damage
your trolling motor, electronics and other boat accessories. To minimize trolling motor interference, ensure that the fish finder and trolling
motor are powered by separate batteries. Please refer to the Battery & Wiring Installation and Motor Wiring Diagram sections of this
manual for correct rigging instructions.
The Universal Sonar Cables are shielded to minimize interference. To protect this shielding the cables should not be pulled tight against
sharp angles or hard objects. If using cable ties, do not over-tighten. Any excess cable should be bundled in a loose loop of no less than
4" in diameter. In certain situations, air bubbles may adhere to the surface of the Universal Sonar transducer, and effect the performance.
If this happens simply wipe the surface of the transducer with your finger.
NOTICE:
Universal Sonar does not support imaging screens that require higher frequencies such as 455 kHz or 800 kHz (Down
Imaging, Side Imaging, etc.). Down Imaging (DI) specific units are not compatible with Universal Sonar. See compatibility chart for
a list of compatible fish finders at minnkotamotors.com.
The connector for Universal Sonar exits the trolling motor below the Control Head and consists of a 4-pin plug. An adapter cable
(MKR-US2) that is sold separately is required for all installations. For a current list of compatible fish finders and the correct adapter
cable, or more information on Universal Sonar, please visit minnkotamotors.com.
