I can't afford at this time to send my SeaDoo to a shop to have the oil changed and am a little confused on how to do it. I change the oil in my truck all the time but have found it is a lot different in a PWC. According to the disc I got off the intereat about SeaDoos, it says that I have to siphon the oil from the dip stick area but also at the same time have to crank the engine without actually starting the engine and that is where I get lost. It also says to repeat this process. Why is this step necessary and is it a vital process in the changing of the oil. Is there anyone out there that can give me tips or instructions on changing oil. Would appreciate any feedback. I own a SeaDoo GTX 4-Tec. Look forward to any suggestions.
