Scene 79 (according to the clapperboards), so after the Macao scenes. Now things are starting to get really confusing, unless we assume that:
a) Fethiye is doubling for some Asian location.
the yacht transporting Bond and Severine is nevertheless registered in Turkey, hence the Turkish flag.
Yeah. Bond must be taken to the Japanese/Chinese island onboard the yacht, as Shrublands originally thought.
But Bond's 'death' could also still take place on the same yacht in the PTS.
How do we know it's an action sequence?
It's an action sequence featuring Bond and Severine on the yacht in Turkish waters.
There are stuntmen listed in the character list (Boat Crew - Stunt).
