There is a simple explanation for what has occurred. The diving stand that you have installed now was originally installed to accept the non-competition model diving board (aka the 16' Duraflex Board). The board you just purchased is the competition model diving board (aka the 16' Modified Maxiflex Model B "Cheeseboard"). If you were to lay a 16' Duraflex Diving Board next to a 16' Maxiflex Model B "Cheeseboard" (upside down) the first thing you would notice is the rubber channels on the underside of the "Cheeseboard" are 5.5 inches farther back than those of the 16' Duraflex Board. This is because the competition model board bends at a point that is farther back than that of the non-competition model board and therefore the installation footprint of the diving stand with Cheeseboard is 5.5 inches different from the installation footprint for a diving stand with a 16' Duraflex (non-competition board). The quickest way to ruin a diving board is to allow a metal on metal contact situation where the unprotected metal ribs of the diving board are allowed to bounce directly on the metal of the fulcrum roller. (Your $3500.00 "rocket ship" can become a $60.00 piece of scrap aluminum very quickly!)
The simple "fix" for this problem is to order a set of eight six-inch rubber channels with glue kit and attach them to the underside of the board directly in front of the existing rubber channels. While this will NOT allow you to get the full range of motion for the fulcrum back past the number "7," it will protect your diving board by making sure the fulcrum does not "roll off" the existing rubber channels as is the case now.
The correct "fix" is to un-install the main support (legs and fulcrum box) and re-install them 5.5" farther back OR remove the ladder assembly and re-install it 5.5" farther forward (assuming your pool depth and slope would allow for this moving the board forward). Most schools or clubs in your situation choose the first option until they have the time and money to do the 2nd option. Choosing the correct "fix" method not only protects your diving board from the "metal on metal" situation but it also allows the diver to get the full range of intended fulcrum settings.
Whichever method you choose -- it should be done before anybody is allowed to dive off the board. You never want the unprotected metal diving board bouncing directly on the metal fulcrum -- properly positioned rubber channels are a must!
