so i am done stripping my new project it is a 76 waikiki day runner 19ft
i am putting a 454 in i am leaning towards putting a blower on it not sure yet depends on the little bro..
so figure 600+ hp min  :obut the question at hand is the boat has a jacuzzi jet "wj" i took the bowl off and the impeller is chiped pretty good and the bowl looks like it is missing pretty good chunks out of the leading edges.

so do i spend the $1800 for the energizer??  or since i am going to be doing glass and paint work look for a new pump??
dose anyone know what kind of speeds i will get out of this boat with a energizer wj???
secondly what is a good setup for this hull???

and i guess lastly am i barking up the wrong tree thinking this could be a 70 mph boat???

thanks for all your input

so I have an itch for a boat i went to lake havasue a few years back and got a chance to drive a jet boat not sure what it was but it had a bbc w/ tunnel ram and was the bitchenest thing it was scary fast to me... well now here i am I saw a few boats on craigslist and my interest is back to full throttle I and am ready to jump in but i am having a hard time researching hulls and finding out were to spend my money wisely.
I have found a few tahiti projects but they have 455 olds and panther pumps. from what i have read that is a bad set up. question #1 how much skill is required to change over to a berkly pump? #2 are tahiti hulls good?  i also found a "can am" boat that is pretty restored other than needing a motor it looks cool but i know nothing about what is a good hull and what to stay away from.
any help or advise on what to look for when finding a hull or boat would be greatly apreciated.
