submerged evinrude 175

no, never got it to turn. nothing to grab on to. i broke the center bolt, tapped it out, broke another one! tried vice grips on top of crank, removed flywheel first, but it just kept slipping. thinking i might stop by welding shop tomorow and get them to weld a piece of pipe to the flywheel so i will have something to turn. cant think of anything else.
