I recently mounted a 2 inch T&H marine spacer kit on my 12 inch Rapid Jack with the included 1/2 inch coarse stainless bolts. It seems to me that these 1/2 inch bolts might be a bit overstressed supporting a 250 . Has anyone ever had any problem with breaking 1/2 inch transom mount bolts? I measured the factory holes in my merc 250 XS and feel that the 9/16 bolts would be better suited. --- mike
