I have snapped off a head bolt and can not figure out what material they are made out of. I ordered some new bolts for the head and the exhaust covers on the block since I snapped off 4 of those while removing them. The bolts I ordered are probably going to be back ordered and I need to get my boat back on the water this weekend. What grade bolt would work in place of the factory bolts in order to get my powerhead back together until the new bolts arrive. The bolts that snapped are M8 x 1.25 60mm and M8 x 1.25 40mm.
