mercury mirage plus 19" prop, hydraulic jack plate, and trim tabs will give you 50+mph.
You're motor might be too high already if you can't get the bow to porpoise w/ full trim.

Not too high, if anything, too low. The prop doesn't break loose until it's trimmed up almost all the way. I've got the cavitation plate about 1" above the bottom of the hull and it's covered with white water when running. Holds real good in turns, too.
I was thinking of raising the motor up one hole. Don't want to spring the $$ for a jack plate. I'm running a Mirage 21 and the rpms are lower than I'd like, closer to 5000 than 5500 at WOT. Maybe I should try a Mirage 19. My wife may throw me out if I add another one to my prop collection. It's getting pretty impressive.
