Is this safe to vent a portable ac? ac's can get really hot.

I've never owned a portable AC. If there is a 4" circle shaped vent hole on the portable AC, it should tolerate the heat. Stationary ACs condensate water, there is no vent hole.

anyone use this for garage auto exhaust tube?

I am currently using this to exhaust the air in my wood shop

Is this suitable for marine use?

No paperwork came with it indicating whether it is USCG compliant (if there is such a requirement). If you want to use it as a duct for a bilge blower, I would say go ahead and use it. If you are concerned about fire retardancy, I suggest you contact the seller first.
