dont no if the layout of these is the same for all boats, i have a mariah 180 i'm gonna try and explain, it has the large sun pad on the back of the boat, either side of the enging box it has 2 vertical pieces that hang off the rear sun pad, these make up the rear part of the jump seats then seperate cusions make up the bass of the seats. the problem is these vertical slabs are very weak and 1 of them has broken off the horizontal pad, best to get the whole thing replaced????????? sorry not very good description
