I have a 2007 Mirage Adventure. The plastic threads within the cam column have stripped out on one side and when pressure is applied to the pedals the stainless allen head bolt pops up and the cam lock pops out of place. Does anyone have any suggestions? I have seen some posts that suggest the use of epoxy or varying forms for external repairs to the cam column but am concerned about internal use. Would drilling a hole through the cam column and using a tee nut on the bottom of the boat work? Looking for options here... Thanks, Ken

There were two lengths of cam bolt - the initial design had short ones - later on these were changed for longer ones. If you have the short ones perhaps swapping them for the longer ones could be a solution?

The '07s already use the longer cam bolt.

Put a small amount of epoxy in the hole, screw the cam bolt in and adjust the height before the epoxy sets up. Make sure no epoxy gets on the cam lock knob. If it does, simply spin the knob every few minutes until the epoxy sets up so it will not bind the knob. That should do it. Although epoxy doesn't stick well to Polyethylene, it should give you enough "bite" to stabilize the bolt. Use a good marine epoxy.

The cam columns carry a lot of stress and are a weak link in the system -- drilling a hole would would be detrimental. Similarly, although Hobie makes a helicoil insert, I would not recommend it -- it adds additional stress to the cam column. 8)
