Yes It will decrease, as per Arcemedes object with same masses upward buoyant force is higher for object which has larger volume area, so when stone is on boat, it increase boat weight and so upward buoyant force is high for boat, but when It is thrown its upward buoyant force is less with compare to when it is on boat, and upward buoyant force of boat also decreases because stone is thrown, so ultimately upward buoyant force decrease than means decrease in water level, hope it will help :)

I think it will decrease as when the stone is on the boat the volume of water it displaces is more than when it is thrown into the sea. as more volume of water is displaced the more water level goes up we can say that water level will be higher when the stone is on the boat.

The amount of water displaced is equal to the mass of the object immersed. Since the net mass of objects in water is the same, the same amount of water needs to be displaced. Hence no change in the water level.
