• Always use good quality stainless steel
hardware when mounting the base.

constructed to provide a strong
mounting surface area.

• The three (3) vinyl spacers will help prevent
any hardtop compression. When installing
through a hardtop, make sure the top is
foam or core filled. It is recommended to
use included spacers to fit inside where the
mounting bolts pass through to ensure that
when the bolts are tightened the top is not
compressed.
• Position the mount with the antenna or light
attached so that it will not interfere with
other hardware on the top.
• Route electrical cables to boat’s control
panel and attach wires per manufacturer’s
recommendations.
• Before installing VHF Antenna or LED Light
Tube, apply a thin layer of marine grease or
anti-sieze to the threaded shaft.
Thank you for purchasing the TACO Marine Grand Slam 850 VHF Antenna Mount or Grand
Slam 950 Anchor & Stern Light! As a family-owned and operated business since 1959, we
take pride in oering the highest-quality, innovative products with excellent customer

mount or installation, please contact us by visiting tacomarine.com/contactus.
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.
7. Ensure the Black wire has a good connection to battery ground.
8. Operate the unit in both directions. The unit will automatically stop at full-up and
lay-down positions.
9. Connect wire antenna according to manufacturer's instructions.

LIGHT
The light assembly is composed of two parts – one (1) Lamp
Assembly and one (1) Stanchion.
EMERGENCY RELEASE OPERATION
Using a standard flathead screwdriver, remove the set screw (A) located on the side
of the GS-850 and GS-950 base while holding the Antenna or Anchor & Stern Light
shaft, being careful not to let the shaft fall. Once the screw is removed, gently lift up
on the shaft and reposition the Antenna or Anchor & Stern Light. Once repositioning is
complete, gently push back in the shaft until the screw holes are aligned and re-screw
in the screw with the screwdriver, making sure not to over tighten and strip the threads.
Repeat this process whenever manual override is necessary.
1. Thread the LED light tube to the GS-850 mounting base.
Note: Apply a thin layer of marine-grade grease or anti-seize to the threads before
installing.
2. Noting the sticker that reads “TO BOW” on the light, position the light properly for
anchor/stern designation.
3. Attach your 18-Gauge, 3-wire cable coming from the helm to the 18-Gauge, 3-wire lead
out of the GS-950 stanchion/tube assembly (refer to figure 4 on page 8).
4. Connect your chosen switch (not included) per manufacturer’s recommendations.
5. Mount the switch to your chosen location at the helm.

occur. Therefore, before drilling, it is recommended that all template
