Handy Tips
2 / GS-312/GS-314
®
• Prepare for installation by ensuring the mounting
surface is clean of any grease and/or dirt.
• Ensure your Canvas T-Top, Arch or Hardtop is
suitably constructed to provide a strong mounting
surface area for your center rigger base.
NOTE: The maximum hardtop thickness allowable
for GS-312 is 2" and for the GS-314 is 4".
• The center rigger has no lever to turn, as it is
intended only for up and down vertical movement.
• Turning the crank assembly handle will allow the
center rigger to adjust to the desired height.

• It is recommended that the center rigger be in the
horizontal position similar to the outriggers when the
boat is at cruising speed.
• The supplied template is only a guide to help align
base for true hole positioning. Make sure nothing is
rubbing in the 3-1/8" hole. There should be a small
gap all the way around.
• Always use a nylon 5/16" washer underneath any
stainless steel washer to prevent corrosion of the
Grand Slam anodized aluminum mounting base.
Place bead of marine-grade sealant around hole in
mounting plate.

• Always use good quality stainless-steel hardware, such
as bolts, washers and nuts, when mounting the base.
• Both the GS-312 and GS-314 incorporate a folding
crank handle. The folding crank handle folds ush with
the rotator base.
Do not attempt to weld the base to anything.

Installation
IMPORTANT: To mount the GS-312/314 Center
Rigger Mount to a canvas top frame, TACO
recommends ensuring the necessary extrusion
plate is of high-quality material and installed
by a reputable welder who can verify the top
size and structure can support the mount.

CANVAS TOP
1. Prepare the canvas for installation by
cleaning it.
2. Use an old filet knife and heat it up with a
torch to where it's almost red-hot. Use the
hot filet knife to cut and sear the canvas in
order to keep it from unraveling.
3. Find each pre-drilled hole and mark it with a
magic marker to make it easy to find.
4. Use an old screwdriver and heat it up with a
torch as done previously with the filet knife.
5. Use the hot screwdriver to poke a hole
through the canvas for the bolts.
6. Go around the main opening and each predrilled hole with clear marine-grade sealant
before you set the base.
7. Set the base through the hole and assure the
bolt holes are aligned.
8. Using the Head Cap Bolt, place the stainlesssteel washer first, and then follow it with the
nylon washer.
9. Use the Allen wrench to screw the hardware
into the base.
10. Wipe the extra marine-grade sealant o the
canvas.

ATTENTION:
Since the canvas top will have pre-drilled holes,
there is no need to use the included backing
plate, spacers, bottom washers and the hex nut.

USING A
SOLID PLATE
1. Locate the AFT end center of your hardtop.
2. Using the included drill template, mark the location of the mounting holes and the 3-1/8" hole
cut out onto the hardtop.
3. To prevent movement of the drill template, tape the drill template to the hardtop.
4. Before drilling your bolt holes, use the hole saw to cut out a 3-1/8" diameter center hole.
5. Drill the hardtop from both sides (starting from the topside down halfway and finishing from
the bottom side up). This will prevent chipping or cracking of the fiberglass.
6. When finished drilling the 3-1/8" hole, set the base through the hole – being careful not to
scratch the anodized finish of the lower components.
7. When the center rigger is aligned, mark and drill out the bolt holes.
8. Place a circular bead of marine-grade sealant under the top plate of the center rigger and
realign the center rigger with the marked holes.
9. Using the backing plate provided, add a bead of marine-grade sealant on the underside of
the flat plate to prevent water drips.
If you are installing through a solid
plate already on your boat, please
read the following instructions.
10. From the underside of the hardtop, place your backing plate and attach the remaining
hardware.
11. Securely bolt the base to the mounting surface.
12. When installing the center rigger pole in the center rigger mount, pull the mushroom pin out
and twist it counter clockwise and it will stay in the open position. This will allow two free
hands to easily install the pole into the mount.
13. Align the hole on the base of the center rigger so the mushroom pin can find the hole and
lock it in place. The mushroom pin locks back into the position if the hole is aligned. Try to
pull the center rigger out of the mount to ensure it is locked in place.
RUNNING
NOTE:
When not trolling, crank the Grand Slam center rigger fully
clockwise (when viewed from underneath), back to the “run”
position using the crank handle and retract the center rigger.

How to use
When trolling with a center rigger, you can troll
it far away from the boat and away from all
other outrigger lines. In most applications, the
center rigger mount should be set at the highest
vertical position and should be the farthest
line away from the boat. With more lines in the
water, the higher the chances to cover a wider
area – thus pulling more baits or lures better
stimulates a school of fish.
A center rigger can accommodate only one line.
Center rigger poles 8' to 12' are ideal for boats
up to 35'. Our carbon fiber center rigger can be
used on boats up to 50'.
Similar to an outrigger, when a fish strikes your
bait or lure, the release clip opens and allows
your fishing line to come free of the center
rigger line so you can reel in the fish.
How to clean
Always use a mild, non-abrasive soap and lots of fresh water. Thoroughly wash the aluminum with a soft
towel or sponge – utilizing lots of soap and water to remove all dried salt crystals and other contaminants.
Rinse completely with direct water pressure. It is recommended to use a small amount of marine-grade
lubricant where the center rigger arm comes out of the base. This will keep the seals lubricated.
Safe Cleaners Harmful Cleaners
Mild dish washing liquid, specialty marine cleaners:
Sea Safe Boat Wash, Boat Wash Concentrate
and Super Suds.
Safe Lubricants:
CRC Corrosion Inhibitor, Corrosion Block
and Get Some Extreme.
Bleach (Clorox, etc.) and mild abrasive cleaners:
Ajax, Comet, Soft Scrub, Rubbing Compounds, etc.
Strong cleaners:
Such as Muriatic, naval jelly or aluminum acid.

WARNING
All center riggers (telescoping and fixed) in the
extended position are susceptible to breakage
while operating the boat at high speeds in rough
conditions. TACO Marine Tele-Outriggers are designed
for increased durability to ensure a long and useful
life. Nonetheless, it is recommended that certain
precautions be taken to avoid unnecessary damage.
Use good judgement in rough seas. It is recommended
that you retract the center rigger before reaching high
speeds resulting in “pounding” and “whipping” that can
cause damage.
Excessive release clip tension or faulty clips can cause
unnecessary loads on center riggers and mounts that
result in failure. It is recommended that you check and
adjust your clips before each use.
