the base should face out and the taller end of
the base should face forward.
Repeat step for all 4 bases.

Step 4: Determine Mounting Locations
Once you determine the general position, use masking tape to protect the gel coat where you will be
drilling. Holding the bases in place, use a permanent marker to trace the position of the base onto the tape.
Unlike other towers, the mounting locations for your
MT7 do not have to be level - all that matters is that the
header is level (see Step #5). Depending on your boat's
construction, your base mounting locations may need to
differ to get the header level.
TOP MOUNT SIDE MOUNT
PRO TIP: Depending on your boat's shape
you could have one top-mounted and one
side-mounted leg.

Step 5: Level Header
Mount the front tower legs to your boat.
Level the tower's header from front to
back, ensuring the header is not higher
in the front as this could cause problems
installing a bimini top.
1.
1.
2.
Determine the angle of the rear support leg
so that the header is level by adjusting the
position of the rear bases.
3.
PRO TIP: If you are installing the tower
while the boat is on a trailer or other non-
level surface, we recomend installing the
header at a slight downward angle (~3°)

3.
IMPORTANT: If the rear bases have to be mounted lower than the front and you are
unable to level the header using the above steps, optional risers are available upon
request. Contact our support team at [e-mail] or 877.778.6937
Step 6: Reinforce the Mounting Locations
Once your base placement is determined you will want to reinforce this area. We recommend 3/8 MARINE
GRADE PLYWOOD to be glued in using 3M 5200 adhesive.
Plywood will be installed vertically as shown below for side mounted bases or horizontally beneath the
gunwale for top mounted bases.
PRO TIP: You can cut the 3/8 Marine
plywood to the size that you will need to
create an effective mounting reinforcement.

Using the Monster Paw as a guide, mark the position of the two mounting
holes. Start drilling IN REVERSE to not crack the gel coat, then switch to
forward drilling and completely drill through boat.
Chamfer holes. Repeat for each base.

Measure corner to diagonal corner, and visually try to place the ski
tow at the center of the boat. Make sure the measurements of one side
match the other, this will ensure the tower is squared up.
