I have a lot of old zinc anode remnants from the boat hull hanging
around discards from the annual haulout. Each year I also replace the
anodes in my Yanmar 2qm20 engine, which are tiny, but more expensive
than the much larger tear drop hull anodes.
The engine anodes are just zinc molded on to a thread. Would it
difficult or in any way dangerous to melt an old hull anode down to
refurbish the engine anode?

There are standards for zinc oxide fume, and people that are
overexposed can get zinc fume fever (which will pass), and also you
can develop an occupational asthma from repeated exposure. But molten
pure zinc (as opposed to zinc oxide0 does not cause health problems
beyond the obvious burns if you pour it over yourself. The melting
point is 420C.
