before you go down that rabbit hole, what are your goals, hows the boat run now? sometimes its easier to find a boat with a pump you want rather then swap it out, unless you have a lot of time and fiberglass skills.
Jet Boat Performance has a kit that changes out the bowl to be able to add droops and place diverters. search the forum its came up several times. from what I've read the cost/ performance from an energizer kit you're better off getting a different boat with the pump you want. unless you're having problems with your pump now, run what you got...  https://www.jetboatperformance.com/jet-boat-parts-and-services-atascad-1

thank you ..my new motor is going to double what the old one made .. I know certain shafts etc can only handle a certain amount of power I'm just preparing just in case mine breaks if I can repair it or not.. but thank you very much.

it doesn't have anything so I'm assuming a wj.. it's a pretty old jet and my parents had to have it serviced and once more before that.. I dont have problems it's more I'm looking what I can do to either make it stronger or a different jet.. because I'm building a new motor that's going to make alot more power than the stock motor that was in it.

Its going to be a 350 bored 40 over soon to be 60 then stroker crank big aluminum heads potentially a blower on about 4 to 8 pounds of boost.it will make about 400 to 500 hp without the blower.. big blocks are common I wanted to do something different.
