I have a 07 21XRD and every time I use the boat I see the rubber insert coming out of the channel of the rub rail. When I roll the rubber out of the channel I see the Phillips screw has backed out and itÂs pushing the rubber out. It does it in a different spot every time and 3 or 4 back out at a time. Has anyone else had the issue with there rub rail and can I stop this from happening every time I use my boat?
