The suggested procedure is perfectly acceptable and will not harm anything.
You may want to dilute it by 50% just to make it go further. You can also
clean the algae from the boat using the solution. Use a good respirator,
the fumes will really hurt your lungs. Skin protection with a rain suit
and a face shield is advisable also. Have done the procedure on many boats.

I almost fell down when the yard told me they get $185 per side to
sandblast, epoxy coat, and paint the running gear on a boat.......I
must have looked disoriented after leaving the office, because a guy
evidently overheard my request and approached me as I was leaving the
yard.

He said what the yard is proposing is a complete rip-off, as he's been
using muratic acid to clean props, shafts and rudders for years. He
said it restores them to pristine condition. Evidently, he sprays it
on, let's it sit for a while, and rinses it off. He said it's then
pretty much ready for epoxy and paint.

Anyone tried this before? I don't want to melt my running gear! 8)
