Looking to buy a 1998 GTX, Wanted to know all the info on a jetski on what needs to be checked and done to run these skis. I was told that some skis need a mixture of oil and gas to put in the fuel tanks and so on. I am looking into getting a project jestski and the owner told me the ski needs a carb rebuild and some regular tuneups and tlc. Please let me know wheat there is to know about these jet skis and it its hard to work on them. Thanks
