finally got the cylinder head off.

but some bad news:

to get it off (at least, let me rephrase that, in the process of
getting it off) I broke the bolt. Thats not such a bad thing, because
it now does make the evinrude a donor completely.

also, I found a bit of a knick on the cylinder head, BUT I think that
the gasket and the cylinder itself don't make that such a huge issue.
The cylinder doesn't come out and make a 100% connection where the
knick is, so in my niave mind it shouldn't (maybe not) cause much of an
issue.

If it does, it does and I'll just re-thread the original.
