I just bought an 05 premier dna 141, and i went to put the fins on and the board like dimpled when i tightened the screw down but only on one hole the other 3 were fine, and the one the dimpled i ddinet even tighten as tight as the other ones, it was botherning me so i loosened it and tightend it with my hand then a lil more with a screw driver, but not alot and it still did it. well it was bothering me and i took the fins off and noticed that one that hole there was like a gap between the top sheet and the core, but all the other holes were solid all the way thru. so im worried that water is going to get into the core thru this little gap. has anyone else had this happen? should i try to get the board warrentyed? or will it be fine? i dont get to ride til april so if its a problem i wanna get it fixed or replaced before then.
