My concern would be were are you going to use this 22' boat with 500hp in it, fifteen years ago I had 220 Baja that had a BB in it that was pumped up to almost that HP and it went mid 70s WOT, the problem was we boated at LOTO and very rarely could I ever open it up on the Summer weekends because it was to small, after the one time I opened her up mid day on a Saturday it scared the chit out of me, I put it up for sale the next week and bought a much heavier 312 Formula with twin 502s, now I have a 353, just be careful with whatever you do.

This was going to be my response.......you'll spend a fortune making the boat go faster and in months realize it's not big enough for what you want to do.
Buy a bigger/faster boat is nearly always the best route to follow.

go bigger and faster. By the time you upgrade the motor and steering you could have sold your boat and had a bigger boat for not a lot more. By keeping your boat stock it will also sell quicker. If you want to go bigger in a few years don't wast the money to upgrade that boat, you will never get it back.

As stated it depends on where you boat and how much you like the boat. I had a 19 foot boat(similar to a Donzi Classic 18) that came with a 250hp 5.7L Volvo Penta. I sold the engine complete and for $1500 more bought a 320hp 5.7 Volvo Penta complete. So, for $1500 I picked up a 6 year newer motor, MPI and 70 hp. The swap was a breeze and the boat went from 59mph to 65mph with much stronger acceleration.

Some of the folks on here are out right comical for saying ''sell the boat and start over''. 
If you like the boat then keep it, if your a regular on the bay, then a 22ft daily might not suit your needs. Does the boat have a alpha or B1 on it. You could pull the engine, build a nice sbc built for boost. Even a stroker sbc over the winter. Not sure what exhaust is on the engine now, but having a labbed prop done, a new exhaust, if the engine is efi, you could have a computer reflash done to start. That will def make more power, give you a few mph in it self.

There's a BIG difference between be ABLE to do 70, and WANTING to do 70! 70 in a 22 ft boat while exhilerating, can be scary! Even on relatively flat water, chine walk and steering problems can jump up and bite you quick. I had a Crownline 225LPX /496 and it would do 60-65 on a good day, but even that slow it wasn't the most stable boat. I decided that in order to do 70+ COMFORTABLY, I needed a bigger boat. So I did what any normal, rational guy would do, and got ten foot itis! LOL! Seriously, figure out what you want, and where you want to do it and reverse engineer the issue.
