Just picked up a '94 Nacra 5.0 to replace my Hobie 16 which went "missing"(coincidentally a few hours after I got the Nacra I found my Hobie 16 disassembled and for sale on Craigslist - now I have two cats).
The story of this Nacra was that it was used a few times on a fresh water lake in central florida then spent years under a carport. The keels are in perfect shape and no signs of any corrosion. However it has a bent mast support rod (I suspect the mast was not rotated when unstepping) and came with small Hobie sails).
I am not having any luck removing the bent rod. The nuts loosened up easily (although the top is limited by the bend). However the rod will not move up and down. It spins freely. I had planned to cut the rod between the lower nut and the crossbeam and then simply push the top half up. However the rod will not budge in that direction so I have not cut anything yet. Could the compression tube(? aluminum) have fused to the stainless steel rod if lube was not used during assembly? I have been soaking it as best as possible with penetrating spray for two days without any luck. I do not see any obvious corrosion anywhere. Am I missing something?
