587 to 717/720 swap?

[Waterrocket20]

Hello wondering if anyone has done an engine swap or knows about an engine swap in a 93 gtx that has the 587 in it? I love the fun u can have with the flat bottom hull but want more speed to keep up with buddies. I read a little about the 717/720 but wondering what would all have to be done to the ski to do this? Thanks

It will bolt right in but you need the 720 carbs electrical and exhaust.
