1320clout

I was about to buy a 1990 Centurion Falcon today that only has 300 miles on it but the floor is soft and I thought i read online that this boat in 1990 was the first composite stringer for Ski Centurion. I looked at the boat and can see that the floor is still wood but the stringers look solid and fiberglassed perfect. I found 2 different sites that have opposite information one saying its first year of composite stringer and floor and one saying its all wood till 1992. I have a 1990 Supra ts6m now that i need to do the stringers on and was hoping to buy one that doesn't because I'm not looking forward to the project. New floor i have no problem doing. Can anyone help that knows for sure if the 1990 Ski Centurion falcon is composite stringer or wood. If it is wood is my best bet just checking the motor mount bolts? Thanks ahead of time for the help. Chad
