slack for tilting and turning the unit and attaching the connector. (The 

snug fit of the push-on waterproof connector requires some force to 
attach.) 

Align the bracket over the cable hole with the cable slots facing away 
from you and fit the cable through the slots. Fasten the bracket to the 

dash using the two screw holes. 

Attach the unit to the bracket by first connecting the power/transducer 

cable. Then, hold the sonar unit vertically and slide it onto the bracket 
from above. (The back of the unit should be touching the front of the 

bracket as you lower it into position.) As you push down, the unit will 

lock into place with a distinct click. 

 

To adjust the vertical viewing angle, pinch the ratchets with one hand, 

then tilt the unit with your other hand. Release the ratchets and the 

unit locks into the new position. You can also turn the unit on its 
special swivel base for a better horizontal viewing angle. To dismount 

the unit for storage, press the ratchets and lift the unit off the bracket. 
Portable Sonar Installation 
Like many Lowrance products, these sonar units are capable of 

portable operation. The X51 Pro uses the optional PPP-12 portable 

power pack. The PPP-12 package includes the power pack, battery 
adapter and a portable transducer. Batteries are not included. Each power 

pack has a storage compartment for the portable transducer. The PPP-12 

can be used with eight AA alkaline batteries. To use a portable power 
pack, you simply install the batteries and then attach the sonar unit to 

the power pack's bracket.
