Can anyone assist me on what to do first. I just picked up my machine(2000 SeaDoo GTX) from the deal(after having battery replaced) Took it out and it sputtered and and just would get enough gas to make it go(Though the back end was sinking for a minute but I knew my plugs were in). I was able to get it to go about 10-15 mph initial with a lot of sputtering then after about 20 minutes It almost got to speed but just seemed to be missing a beat. Any suggestions. Thanks, Jerry in N.Y.
