The apollo propeller does not have the cupping like the old Michigan rapture it replaced, so what is happening at high speed is it just cannot bite as well, thus your ventilation. What you could potentially do with that prop is take it to a good prop shop that can add more cupping to the blade tips and around the trailing edge of the fins. What this will do is give you better bite on the water, and the the overall boat will be lifted more. What you may find with this is you might have the option to raise your motor another hole or two, keeping you in the same RPM range, but yet a faster and better handling rig.
As for the reliance prop, it doesn't seem to be much different than the apollo as I look at it, so I would surmise that it would be fairly similar in characteristics. If you could take one to test it, then you would really be able to get a feel for what that prop is capable of, since there is really no way to tell just how well a prop will perform unless you run it. Even from two identical boats with the same identical motor mounted exactly the same, one prop may work on one boat, but not as well on the other.
It can be a fun project to figure it out (if you like that sort of thing).
