One thing that DID happen is now I get the "classic" grey/black smoke
when I push up the throttle past where the RPMs get any higher, telling
me too much fuel for the engine speed. DEFINITELY a sign of
over-pitched prop! So: gotta pull her in the spring to check/replace a
thru-hull, so I'll reduce the pitch an inch, maybe 1.5 inches....

Not necessarily. We are properly pitched, but have a little extra
throttle to throw in which blows pretty black. Even when we were
under-pitched our first season, that happened once we achieved the
engine's max RPMs and the governor cut in.

Measure the revs before you change the prop.
