Heres some videos of one that was supercharged, also obviously should change out stock exhaust, what would be a good set of exhaust for this thing , but I could also keep the silent choice option that it currently has .

Looks like you have been pondering this for a while.

Looks like a fun little boat. However, since it is set up as an all-around family ski type boat, it probably has a fairly flat bottom on it (probably 20-22* deadrise), which means it will ride over the top of wakes rather than slice through them like a 24* bottom would do. I would be worried about it getting major air and becoming unstable at really high speeds, especially if you encountered some sizable wakes. You are obviously more familiar with the boat than I am, but I do know that sometimes the safe limit comes up without much warning, and you can find yourself in a world of trouble in the blink of an eye.

Don't forget about your drive upgrade, if its in good shape and not broke now...it will be. Talk to thirdchildhood, he put a 525EFI in his Donzi 22 and it runs out well, no supercharger to mess with.

Have you tried a 4-blade prop on it? Light hulls with a high X-dimension often respond well to those props.
You need to talk to a marine engine builder with a lot of experience with superchargers. Guys like Eddie Young, MER, Haxby would be good sources to make you aware of what you will need to do to get your 454 to live with a supercharger. There's a lot more to it than just slapping one on. You might get by with that for a little while, but eventually you will blow something up if not set up right.
You might find more experience with that hull over on ScreamandFly.com. They cater to the smaller jet and ski boat hulls. OSO has more guys with experience with the bigger hulls, although there is a lot of crossover here.
