Fitment Instructions

Step 1.

First look for any pop rivets or bolts sitting on the inside of the gunwale/bumper channel holding the protective bumper rubber on, some models have them and some don’t. If pop rivets are found, make sure the clamp inner jaw (jaw with threaded studs) is not positioned on them as it will damage the inner jaw rubber pads. There is a gap between each inner jaw plate to compensate for any pop rivets or bolts.

Step 2.

Hold the clamp with two hands applying pressure towards the ski to help it sit in position and to assist tightening the clamp and pull up on the shanks to lift the inner jaw into place inside the gunnel area. 

Then use one hand to pull the inner jaw in. Proceed to tighten one knob up lightly till the clamp can hold itself.

Step 3.

Make sure the rack posts are sitting near vertically straight, if not your adjustments or fitting may be wrong and can weaken the clamping strength, the adjustable bottom hull support plate with multiple holes in it dictates the angle the rack posts will be on.

Step 4.

For Yamaha’s & Sea-Doos, make sure the upper hull support plate is sitting horizontally flush and neat in the edge between the gunnel rubber and fiberglass groove where the two meet. (Kawasaki and Honda are slightly different)

Step 5.

Double check that the inner jaw is sitting horizontally straight so it is parallel with the gunwale edge.

Step 6.

Proceed to tighten BOTH knobs at the SAME time with even tension until you have a nice secure, firm fitment. The amount of turns will vary between each make and model Jet Ski.

NOTE: Do not keep tightening till you can no longer tighten the knobs any more.

Step 7.

In the case you experience spray coming up from the rear rack, a splash guard comes with every set for the rear rack, screw into the plastic rack on the inner side with two screws.

Step 8.

For a 6ft Surfboard space the racks approximately 60-80cm apart from each other sitting in the middle of the ski. The rack posts are shaped and profiled for surfboards to slot in with the top - waxed sides facing each other and fins at opposite ends. We suggest always putting the larger board in the bottom slot.

Always double check all the bolts after every few times of use to ensure they are tight, including the one underneath the plastic surf rack post.
