I discovered that my seats were slightly loose, especially the middle one on my boat. They only have the 2 clips the hold the front of the seat. After some research i found that the seats are held down by a thick flexible contact cement. I spoke to the dealer and they were somewhat evasive about what to use. I am sure they make plenty of money regluing seats. I purchased some 3M heavy duty sprayable contact cement at Lowes for 12.50. I put a 1/4 inch bead around the area that makes contact under the seat and on the seat. i allowed it to dry for 10 minutes and clipped it on. We went out the next day in very choppy conditions doing what we do (jumping waves and skiing). It worked beautifully. Hope this helps anyone else that is unsure how to fix their seats.
