Hey guys im not a complete newbie to jet boats ive done plenty of motor builds and installs and only had my last boat for couple years and never had to do any pump work the boat I have now I plan on keeping its runs fine nice family cruzer with plenty of motor but over the winter im buyin a pootoon for the family and I wanna turn the jet boat it up a lil make lil more of hot rod for nxt season however I kno my pump is holding me back I cant seem to figure out exactly what has been done to my pump guy I got the boat from keeps sayin its american turbine but the pump says jacuzzi 12yj/b so im tryin to figure out has it had an energizer kit or something done to it? And im sure its not a hot rod pump should I try to idenify what I got change impeller and rebuild or change pump completly? How much hull fabrication to switch to hot rod pump? It supposedly has an A impeller I dnt believe much of what the guy says just tryin to get an idea for my future plans

Sweet thanx for the info thats what I was thinkin based on the reaserch ive done but wasnt completly sure whats been done to the pump I only plan on tryin to reach 600 horse and realisticly only gettin 5 to 550 anyway so I shouldnt worry bout the pump if its workin fine? If I was to rebuild the pump whats the best options for impellers for top speed? Are these energized yj's worth rebuilding? Could a pump like this ever see 70 mph? Thanx again for the awesome info !

Prob keeping yhe pump not to excited on the idea of havin to glass shit out of the hull and all the fab wrk to change pumps my budget doesnt have much more than 550-600 horse anyways so if this pump is fine for that and I could get a good 65-68 mph I be happy I took pic of my impeller I kno its not a good pic but curioud if anyone can tell kinda if its an A impeller like the original owner says crewchief seems very knowledgable on this subject hopefully he can give lil more insight I got better pic of my unit number plate and impeller any ideas is yhis good impeller for top speed suggestions on something better or is this decent thanx u guys rock!

Talk with riptide84, he has a Berkeley wedge for sale I think, don't know if it will work for you but if its the same bolt pattern why not
