4 / GS-850 & GS-950 MOUNTS
1. Use the drill template to mark and drill with a 1/4" bit the three bolt holes.
2. If your top requires spacers, trim the included vinyl spacers to the depth of your
hardtop thickness. Insert the vinyl spacers into each bolt hole.
3. Place a bead of marine-grade sealant on the underside of the mounting plate. This
helps prevent water intrusion.
4. Securely bolt the base to the mounting surface. Be careful not to deform the top.
5. Connect wire according to Figures 1, 2 and 3 on page 6.
6. Use a 3A fuse in the main +12 VDC power feed (not included).
7. Use a 3A fuse for the light (not included).
8. Ensure the Black wire has a good connection to battery ground.
9. Operate the unit in both directions. The unit will automatically stop at full-up and lay-
down positions.
• Horizontal adjustment is possible to 80° angle. See diagram A.
• The GS-950 features two set screws – one to lock the light positioning in place, the
other for adjustment.

Adjustments to the arm position need to be done
slowly 1/4 turn at a time. It is best practice to use
an amp meter to determine when the sensor switch
disables motor power. Failure to do this could result
in motor failure.

NOTE: TACO recommends
adjusting the angle slowly,
every quarter turn. Over-
adjusting could destroy
the sensor, which voids the
warranty.
10. Screw down the bottom of
the light tube assembly to
the mount.
NOTE:
Before installing the
LED Light Tube, apply a thin
layer of marine grease or
anti-sieze to the threaded
shaft.
