To flush mount the Fishfinder 340C:
1. Trim the Flush Mount Template, and tape it to the chosen
location.
2. Using a center punch, indent the center of each mounting
hole location.
3. Using an 1/8" (3 mm) drill bit, drill the four mounting holes.
4. Using a 3/8" (6 mm) drill bit, drill a hole for a location to
begin cutting the mounting surface.
5. Using the jig saw, cut the mounting surface along the inside
of the dashed line indicated on the template. Be very careful
when cutting this hole, there is only a small amount of
clearance between the Fishfinder and the mounting holes.
You can cut slightly inside the indicated line and then sand
or file the panel, as needed, to obtain the best fit.

6. Install the four mounting studs into the Fishfinder by
screwing the shorter section into the back of the Fishfinder.
Use a 1/16" (2 mm) Allen wrench to tighten the mounting
studs until the stop contacts the case. Be careful not to
"
overtighten, because this can damage the mounting stud!
The studs have a reusable thread-locking patch pre-applied
from the factory.
7. Place the Fishfinder into the cut out in the mounting surface.
8. Place washers over the mounting studs, and then thread
on one hex nut per mounting stud. Tighten all four until the
Fishfinder is snug against the mounting surface. Install and
tighten the second hex nut on all four mounting studs to lock
the first one into place.
