Did a copy and paste from the jet boat section to see if I could get some advise.
Does anybody know?? My search on SST threads gives me the clue that the hulls where built with no stringers. Maybe this was "no stringers" for engine mounting. I removed a center stringer from this hull and plan on replacing it. I did notice that this center member had no contact with the floor..about 1/4" gap. My question is. Should the stringer have contact with the floor? Was this gap there for flex? I really don't see this hull having that much flex or deflection to constitute a gap. Also...It's my understanding that the original way the engines where mounted used a mercruiser pin/threaded type blocks that where through bolted from top of the tunnels?
