LX Series Universal Open Water Dual Beam Transducer
User Guide
Introduction
Thank you for purchasing the MarCum LX Series Universal Open Water Dual Beam Transducer. Now you can enjoy the
superiority of your MarCum Sonar system year round with use on open water! The functionality of your sonar you have
become accustomed to using on ice can be transferred to your boat with a few installation procedures we have listed in
the below User Guide.
Selecting a Transducer Location for Transom
Selecting a location for your transducer is important for proper function. The transducer must have smooth water flow
to operate correctly. If the transducer is not placed where it can experience smooth water flow interference could
result. Turbulent water from the motor’s propeller can potentially cause interference in the form of random marks on
the display. Be careful to not mount the transducer too close to your motor (no closer than approximately 1 foot), or
near water intake or discharge ports.
Also some boats have stakes or ribs on the hull that can create turbulence. Be aware placing your transducer too close
to these can cause interference. If your boat has multiple ribs, a good place would be between the ribs closest to the
engine (no closer than approximately 1 foot).
Installing your Transducer to the Transom
Once you have selected your ideal transducer location you are ready for installation. First, you should position the metal
transducer mount so that the bottom edge of your transducer is level with the bottom edge of the transom. Also, make
sure the transducer is parallel to the water line.
Please note before drilling into your transom you are advised to check your boat owner’s manual to be aware of any
electrical wires, oil lines, etc. that may become damaged.
When you have your mount aligned correctly, mark the center location of the four holes on the transducer bracket.
Using a 5/32 inch drill bit, drill the four pilot holes you have marked on the transom in the properly selected location.
We recommend applying a marine sealant to the screws first, and then attaching the bracket to the transom. Lastly, use
the black plastic retaining bracket and the two remaining screws to attach the transducer to the bracket.
Installing your Transducer to the Trolling Motor
Your MarCum Open Water Transducer also has the ability to attach to your trolling motor using the supplied trolling
motor mount. First, you will need to attach the trolling motor mount (black plastic mount), to you transducer with the
two supplied screws (please use marine sealant on the screws). Make sure the transducer is connected to the smooth
side of the mount (side with the groove).
