Take a look at article on page 26 of January 2022 edition of Antique Outboarder. Your situation may or
may not lend itself to a similar approach.
Methods vary, some will work in one situation
and not in others. Also depends upon resources
A friend had a cutting torch and a steel bolt broken
off in a cast iron engine block ( starter bolt on bottom
of engine.) preheated the bolt and gave it a puff
of oxygen…bolt came out as slag without damage
to thread in cast iron. Slick Trick, but, better get in
a lot of practice first if you do not know how. I say
him do it. Very much like magic…it is one thing to
know how and another thing to actually pull it off.
