it is probably a combination of luck and sealing things up good. 2 of us have 04 sxr eboxes and the salt water got in or they just sh*t out by chance. every one says x2s always have to be worked on all the time but my skis do not brake down at all, till this happened and i think it just needs a coil. i don't even take care of my x2s that well and they always run.
