A boat floating in fresh water displaces 16000 n of water. How many newtons of saltwater would displace if it floats in saltwater of specific gravity 1.17

It will displace the same weight of fresh water i.e.16000N. The point is the body ‘floats'- which is the underlying assumption here, and by Archimedes Principle, for this body or vessel or whatever it may be, to float it should displace an equal weight of water. As the floating body's weight (in air) is not changed, the same weight of salt water will be dispalced.
However, since the specific gravity of salt water in the sea is about 3% more than fresh water, it follows from Archimedes that the volume of water (equivalent to 16000N) will be less by 3%.
Hope this clarifies.
