To swivel mount the Fishfinder 250/250C display:

Tools (not included) — Drill, Screwdriver (Phillips or Standard), three #8 (4mm) pan head machine bolts with matching nuts and washers and a 5/32” (5mm) drill bit, OR three #8 pan head self-tapping screws and an appropriately-sized drill bit for drilling starter holes.

1.Using the swivel base as a template, mark the location of the three holes that are used to secure the bracket to the mounting surface.

2.If securing the base with machine bolts, drill three 5/32” (5mm) holes at the locations you marked. OR, if securing the base with self-tapping screws, drill starter holes at the locations you marked. Starter holes should generally be no deeper than half the screw length.

3.Secure the swivel base with three bolts or screws. DO NOT OVERTIGHTEN.
