Ah Hell Chuck, you missed the point of the question here.

I don't think the OP was asking a trick question. While you and I
understand the relation between thrust and HP, I do not think the OP has a
grasp on it. What was not said, was, "if I use the correct prop to get 2300
RPM at full power, will the 100 HP and 150 HP engine have the same thrust?"

On the other hand, I could be reading too much between the lines, and could
be completely wrong. If so, "never mind" :-)
