I have been overhauling a late '90s Mercury 3.3 2-stroke outboard and as you might imagine, a lot of those pesky M6 stainless bolts are screwed directly into the aluminium castings. Two in the steering collar have sheared. They are stuck so fast that I have broken off a bolt extractor in them both. Final solution is to drill out, but I now have a very hard thing right where I want to drill. Will anything drill though a bolt extractor? I would have thought that it is as hard or harder than a drill. Replacing the casting would cost more than the motor is worth, at Mercury prices. Any suggestions or ideas please?
