Whether you are completely replacing your pontoon decking or just re-carpeting your existing pontoon
deck it would be a good idea to check your current deck bolts while
everything is tore apart. The main purpose of replacing your pontoon
boat decking or carpet is to protect your investment and make sure your
craft not only looks great season after season but is safe as well. To
install these pontoon bolts through new decking pre-drill 1/4" holes
through both the pontoon deck and the aluminum cross channels. Space these holes approx. 12" - 16" apart. Place your new deck bolts through the newly drilled holes and proceed to the underside of the boat to secure the bolts with the new included Flange Nut.
