ASSEMBLY
1. Find the mounting location on the boat. You may even want to use the bottom
bars as a guideline.
2. Place a gasket at one of the front mounting locations and use a pin or marker to
mark through the hole on the gasket and onto your boat. Measure back
approximately 66 or 70 inches*, making sure to stay parallel with the boat trim
line. Repeat on opposite side of boat.
a. *newer revisions of the Vapor tower will have a 66 inch front to back
stance while older revisions will have a 70 inch stance.
3. Drill holes using a 9/16” drill bit and drill through the side of the boat running
the drill in reverse. Chamfer holes using a mounted grinding ball/stone found at
most hardware stores.
4. Assemble mounts onto boat as
shown in image to the right. (Make
sure to follow detailed installation
and instructions manual)
5. Assemble the bottom bars.
6. Assemble the legs.
7. Slide legs into the H-Member and
center.
8. With the help of a friend, attach the rear legs to the rear mounts.
9. Attach the front legs to the front mounts.
10. Now make sure that the H-Member is centered side to side. Do this by measuring
from the edge of the H-Member to the outer side of the corner of the leg.. (Note:
We recommend pulling the corners into the H-Member with a ratchet strap. This
helps preload the tower. You can do this by looping a ratchet strap around the
two front legs and pulling them towards each other into the H-Member. Repeat
this process for the rear legs)
11. Double check and tighten all bolts on the tower.

To lay the tower down:
If the rear mounts are completely parallel:
1. Unthread the (4) bolts located in the center braces of the H-member.
2. Loosen the shoulder bolts on the rear legs and swivels to allow the tower to tilt back.
3. Unthread the shoulder bolts connecting the front legs to the Bottom Bar on each side.
4. Lay the tower down.
5. Reassemble in the reverse order.
