The overheating sounds bad. Hope you were exaggerating.

The black smoke and dying COULD be something else, though: As soon as I
poured on cruise power after our first fill one season (late June after
a November end-of-season fill), we got just about what you describe and
thought for sure I'd put gas into the tank. Long story short: Had to
change the filters twice, then clean the last one (I only carry 2
spares), bleeding each time. Was a BIG shot of algae.
