Just some interesting notes from the tear down...
Both the bow deck vertical supports(not just the horizontal lip/edge like on the SS models) and the lower side supports are solid riveted to/thru the hull. I drilled out the bow supports in order to get the front deck section out, but left the side supports in place for the time being, but will likely drill those out as well for cleanup and painting. I suppose this is what helps to provide the structural integrity to the center console hulls in the absence of the side/dual consoles(or full dash) and side panels typical to the other models.
Both of these areas were also loaded with floatation foam, in addition to what was found behind all the aft side panels, the aft splashwell side enclosures, underneath the full length of the gunnels, under the console, and under the helm seat/fuel tank enclosure. This was all of the white beaded EPS Styrofoam variety. Under the deck consisted of the pour in variety on both sides of the hull, with the center channel left empty, likely to allow for both drainage and the run of wires/controls/steering from the console to the motor. Curious as to whether all this extra above deck floatation was designed as a "replacement" for the floatation that would typically fill the center of the under deck hull as well. Just much more than I've seen on my other two Starcrafts, and the first I've seen it incorporated under the gunnels, but this could be something that became more standard on the 80's models?
Either way, I'll be replacing all with XPS in any areas I can fit it.
