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
