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.
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.
USING A
SOLID PLATE
If you are installing through a solid
plate already on your boat, please
read the following instructions.
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.
