1.   Using the tilt mount bracket (Fishfinder 90) or the 

swivel base (Fishfinder 140; Fishfinder 90 option) 

as a template, mark the location of the three holes 

that you use to secure the bracket to the mounting 

surface.

2.  If securing the base with machine bolts, drill three 

5/32" holes at the locations you marked; or, if 

securing the base using self-tapping screws, drill 

1/16" starter holes at the locations you marked. Drill 

starter holes no deeper than half the screw length.

3.  Secure the tilt mount bracket or swivel base with 

three bolts or screws. DO NOT OVERTIGHTEN.

4.  If you are using the swivel mount, place the swivel 

mount bracket over the swivel base and secure it 

with the short knob.

1.   Align the slot on the back of the Fishfinder with the 

long mounting knob, and slide the Fishfinder into 

place. If necessary, adjust the long knob to spread 

the bracket arms apart. (Turn counter-clockwise to 

widen the bracket arms and clockwise to tighten.)

2.   Adjust the Fishfinder angle, and tighten the long 

mounting knob until snug.

3.  For the Fishfinder 140 (Fishfinder 90 option), rotate 

the swivel mount bracket by twisting it left or right. 

The bracket clicks as you turn it. Select a good 

viewing angle, and then tighten all knobs.
