I read on the Mercury Racing site that the Mirage Plus gives you maximum bow lift. I run a 23p Mirage on my Switzer and the boat is really stable at speed. Tried a 24p Bravo 1 and that seemed to raise the transom. Made the boat seem really loose. Cruise speed was better but top end was equal. My prop is 5.5 inches deep but I only have a 21 degree deadrise. Also I am not pushing the HP you are putting out.
