I picked up a 2011 Kawasaki STX 15F (about 100 hours total time) of eBay years ago after it ingested water while running and snapped a rod, punching out the the block (often referred to as a "window job")).
I got it to support my 2004 & 2008 STX15F's which I have since sold and upgraded to a pair of 2021 STX 160's.
I had completely disassembled this 2011 and scrapped the hull US-KAW11008L011 & notified Michigan SOS of its demise.
Literally everything that could be removed from the hull was and is now in storage and available to make an offer on.
Gone are the seats (I do have the 2004 single piece seat), the display, and the jet pump which I'm saving for my new PWC's as a back up.
Let me know what you're looking for and I'll send pics if it's still here.
I'll also consider offers on the whole lot.
Thanks for looking!
