NSTALLATION

The Fishfinder 250/250C can be flush mounted on a flat panel. When 

flush mounting the Fishfinder 250/250C, choose an appropriately 

sized location for the unit. Use the Flush Mount Template provided 

in the box to determine a location. Check that all cables reach the 

unit mounting location before beginning installation. Always wear 

safety goggles and a dust mask when drilling, cutting, or sanding.

Included mounting hardware—Four 3mm studs, four flat 

washers, and eight 3mm hex nuts.

Tools (not included)—Center punch, drill, 1/8” (3mm) drill bit, 

3/8” (6mm) drill bit, jig saw, 1/16” (2mm) Allen wrench, and 

9/32” (7mm) wrench.

1.  Trim the Flush Mount Template and tape it in the appropriate 

location.

2.  Using a center punch, indent the center of each mounting 

hole location.

3.  Using a 1/8” (3mm) drill bit, drill the four mounting holes.
4.  Using a 3/8” (6mm) 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. 

6.  Install the four mounting studs into the unit by screwing the 

shorter section into the back of the unit. Use a 1/16” (2mm) 

Allen wrench to tighten the mounting studs until the stops 

contact the case. Be careful not to overtighten, as this may 

damage the mounting stud. The studs have a reusable 

thread-locking patch pre-

applied from the factory.

7.  Place the unit in position 

inside the cutout area of 

the mounting surface.

8.  Place washers over the 

mounting studs, then 

thread on one hex nut per 

mounting stud. Tighten 

all four hex nuts until the 

unit is snug against the 

mounting surface. Install 

and tighten the second hex 

nut on all four mounting 

studs to lock the first hex nut in place.
