Is it a hummingbird or lowrance? Unique boat products makes an jackplate bottom cover that makes transducer installation a snap. It has a built in mount that places the transducer at just the right angle in relation to the water and not the boat. The ethernet box can be easily mounted under the driver's console or front tackle/rod locker. Remember to put the unit on a seperate switch so it won't run down your battery when not in use.
