Hi guys, I boutht 2 2004 GTX 4 TECH's about 18 mos ago. They have run flawlessly for two summers. All I have done is change the oil/filters(twice). They each have about 100 hrs total time. I would like to perform my own pre-season maintenance if at all possible. I have purchased a factory repair manual and have most tools, but no specialized Seadoo tools. One area that I need direction is the electronics. I understand that after X number of hrs the machine will audibly warn me of maintenance and can only be silenced by connecting to a computer, presumably only at the factory authorized dealer. Here's my questions: 1. Can a handy guy reasonably expect to perform most/all of his own preventative/season readiness maintenance without the need for a dealer? 2. Is there anything special I need to know? 3. Do I need to connect the machines to a compuetr of some sort for any reason? If so, can I purchase the required program for my own computer? Connection cable? 4. Based on the forum's recomendations I have no problems joining as a "premium" member if that level of membership is what it takes to access the information I require. Thanks in advance, Jim
