Im currently wanting to purchase a jetski but i have never had one. I have a boat and know a lot about boats but i dont know a whole lot about jetski's. A guy has a 1999 gtx rfi and he has about 60 ski's total. He bought out a dealership and works on them regularly. He said with the gtx he is changing something on the rotary valve because it wasn't reaching its top speed. And he's saying this should fix it. I was wondering if that mean something else could be wrong or anything? It has about 138 hours on it which is pretty low. I was just needing some opinions on it. Also he has a 1997 gtx and I was wondering which you think would be better?
