See the outline drawing for mounting hole dimensions and fixing instructions
1. Unscrew the mount base (part C) from the surface bracket (part E) (see figure above). Re-
move the label from over the GPS receiver's socket. (The label may be discarded.) Fasten the
mount base (part C) to the GPS receiver (part A) with the supplied panhead screws, flat wash-
ers and spring washers. The torque for the screws is 1.35 N m.
2. Screw the surface bracket (part E) onto the mount base of the assembled GPS receiver. Use
a pencil to extend the alignment tab onto the surface bracket. Unscrew the surface bracket.
3. At the selected location, position the surface bracket with the pencil mark facing forward. Us-
ing it as a template, mark the position for the three mounting screws and the center hole for
the cable.
4. Using a 3 mm or 1/8" bit, drill the pilot holes. Using 5.1 mm or #7 bit, drill the three mounting
holes. Drill the cable hole with a 25 mm or 1" bit.
Fiberglass -Minimize surface cracking by running the drill in reverse until the gelcoat is pen-
etrated.
5. At the location shown in the figure above, coat the surface bracket (part E) with silicone seal-
ant.
6. Apply silicone sealant to the three #10 x 1/2" self-tapping screws to seal the deck. With the
pencil mark facing forward, fasten the surface bracket in place. Do not block the drain slots .
They will allow any water that accumulates inside the surface bracket to escape. CAUTION:
Do not use a liquid thread locker as it may weaken the plastic, causing it to swell and crack.
7. Wrap pipe thread tape around the threads of the mount base two times to seal it tightly to the
surface bracket.
8. Coat the part of the GPS connector shown in the figure on page 4 with silicone sealant. Pass
the GPS connector end of the cable up through the hole in the surface bracket.
9. Remove the protective cap from the cable's GPS connector. (Save the cap to protect the con-
nector, when the receiver is removed.) Plug the cable firmly into the GPS receiver.
10. Counterclockwise twist the cable three and one-half turns. Then screw the GPS receiver onto
the installed surface bracket. Hand-tighten only . Do not over tighten.
