Warning: Before drilling into your boat, please check that you have clear access to the area beneath and that no objects, wires, or other hazards are present.
Tip: Do not measure from windscreen, cleats or vents. These reference points are not always square and in the same position as the opposite side of the boat. It’s the best to use the front of the boat as the reference point, the top edge of the deck mould, or similar measurement points whenever possible. Always triple-measure and check before drilling.
Tighten the deck mounts firmly so that the mounts will rotate under pressure while turning the mount with the leg attached (note the mounts will be very hard to rotate by hands)
Attach the tower onto the deck mounts. To make your job easier, you can remove the short front curve legs from the tower assembly at this stage, and move the front horizontal bars in or out to fit the rear deck mounts and connect it with M12 washer and bolts. Then lift the tower and re-assemble the curve legs on, rotate it to fit the front deck mounts, and connect to the mounts with M12 bolts and washer.
NOTE: When you have a narrow boat you probably need to shorten the overhead bar to make the tower fit to your boat.
Drill through the predrilled holes in the center section from each side with size 10 drill bit and install bolts and cap nuts. One person will still be stabilizing the tower through this step. Tighten all hardware for completion of tower installation.
Double check If the tower is in the correct position you can fasten all the bolts and screws
