It will rise. The original weight of the boat+ice will displace an equivalent weight of water (say x+y). Now if the ice is removed, and placed in the pool, it will displace some water(x). Additionally, the air occupies the vacant space previously occupied by the ice, it will displace additional weight of water(z).
Add to that the weight of boat (y) so you have x+y+z therefore more water is displaced ie the water level rises.

It should stay the same. When an object floats, it displaces the amount of water that weighs the same as it. So boat (floats) and ice (floats) displace water based on their weight, which doesn't change if you throw the ice into the pool or not.

What if the ice were to melt? Well, it would turn into water. And this water should be the same weight as the ice it came from. This is exactly the same amount of water displaced by the ice initially. So it makes just enough water to keep the water level the same.

When an object sinks, however, it just displaces how much volume it takes up.
