4 / GS-380 / 380XL OUTRIGGER MOUNT
1. Before drilling your bolt holes, cut out a 3-1/8" diameter center hole.
2. When you are finished drilling your 3-1/8" hole, set the base in the hole being careful not to
scratch the anodized finish of the lower components, or to damage the white angle height
position indicator. Use your outriggers to help align the base.
3. 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.
4. When the Grand Slams are aligned, mark and drill out the bolt holes.
5. Bolts, washers and nuts are provided or if you purchase your own, always use good quality
stainless steel hardware when mounting the base. Please do not attempt to weld the base to
anything.
6. If using a backing plate, put a bead of marine sealant on the underside of the flat plate. This
prevents water drips.
7. Securely bolt the base to the mounting surface. Install operating lever last. Insert lever from
the larger open-ended slot, from stern facing position. (The bottom part of the Grand Slam
can be rotated to locate this hole). Lubricate threads with marine-grade oil or grease, making
sure the handle is all the way in.
8. Screw the handle adapter to the mount using the 4mm Hex bolts. Place the outrigger in the
arm and test. Pull down on the lever and move port to starboard. Release the lever, and it
should go into locking positions. There are 20 locking positions. If the lever does not return
up, push left or right until it slides into position.
9. Turn the crank handle to full up and down outrigger position to ensure the outrigger does
not interfere with other top mounted accessories.
10. The pull pin to lock the outriggers is spring loaded. Simply pull out the pull pin, rotate 1/4
turn and release. Place your outrigger into the arm and turn the pull pin to snap back into
position. Then turn your outrigger until it clicks in the locked position with eyelets facing aft
if you are mounting aluminum poles.
INSTALLATION
Always use high-quality, stainless-steel hardware when mounting
the base. Do not attempt to weld the base to any surface.
NOTE:
Always use a nylon 5/16" washer underneath any stainless-steel washer to
prevent corrosion of the Grand Slams anodized aluminum mounting base.
USING A SOLID PLATE
Place bead of
marine-grade
sealant around
hole in mounting
plate.
