How many bottles does it take to flush a four cylinder system?

Based upon my experience, ONE bottle is more than enough.

Is it safe for aluminum radiators? Their website doesn't say.

I have used it in aluminum radiators a lot If the radiator is in bad shape it might leak This is a great product here

What are the disposal instructions on this product?

Just recycle ♻️ at recycling center

Can you use this for boats?

I don't own a "ship" but sure has hell my "boat" has a water to water heat ex-changer that gets strangled by salt and mineral deposits on the lake/sea side, that require a nice acid boil to clean out. The closed loop with coolant in it gets flushed every two years. I would not trust much of what you say about "boats".
