:smile: Carscw, very common problem on those Craftsman. My take is poor design. If they had welded all the way around and put a stiffener plate on the inside of the frame problem maybe solved. I have repaired a few, using the the above idea and have no come backs. I also drill a small hole at the end of the crack to relieve the stress and then vee the crack and weld it up, of course after pulling the crack back together. Zig3, for a kill switch, use the seat safety switch as Carscw stated or setup for a jet-ski.
