How do you remove a frozen bolt from an outboard motor?
Put more penetrating oil in the holes then let it cool. Try to unscrew the bolt again. If it starts, then back it up to tight, then loosen it again to just slightly more than the first try. Keep tightening/loosening a little at a time until either the bolt unscrews, or breaks off.
