I have a buddy with an 05 X30 he bought used from the Spokane MC dealer. He's had the boat in their service dept like 3 times for stupid things, hoses no hooked up, missing air cleaner, etc. Most recently they winterized it (last fall). Over the winter, something blew up & the transmission purged all the tranny fluid into the bilge, and then all over the garage floor. His dog tracked it around for a day before he came home to find quite the mess in the garage & the snow in the back yard.
Ask around in Spokane..... similar stories about them are not tough to find.
