just got a 1995 gts from a friend for my birthday. it was his and his fathers, but they blew the motor. they thought they could fix it themselves so they disassembled it but ended up leaving it in the rain and outside for about a year. original motor was a 580. now i have the sea doo but it has no motor. i was wondering if i had to put a 580 in it again or if there where other engines preferably a bigger size motor that would just bolt on. i don't want to do any modifications to it, i just want to throw a motor in it and go.
