Ok a few things before we all get worked up over a title.
1. Is it in the sellers name? (you didn't specify) If so it should be straight forward, perhaps HE doesn't want to pay for a duplicate.
2. Does he know the previous owner? Perhaps his name, a little switchboard.com search and BAM you get a Phone# and address. Now you call the guy---BEFORE you buy it.
3. Run the HIN through your fish and game commission, they MIGHT be able to contact the title holder and help get the ball rolling.
These simple phone calls can be done in a relatively SHORT amount of time. Title work while time consuming can be easy. Also if it HASN'T been titled it may be easier than you think to get it registered in your name--inquire at you fish and game commission.
X engine--No it's not---probably. That data tag has been removed, that is also more than likely NOT the original engine. Two things stand out, wrong color white. The OEM paint is more of a cream color. Secondly, the rear horseshoe motor mount is black, it should be purple......BUT it could be painted I "THINK" i see a purple speck at about the 10 o'clock position of your red oval.
If you really want to know if it's an X engine you can give the HIN to your dealer, they can get you the original engine serial number and that will tell them if it was an X engine or not----so I have been told by my dealer.
Also you can give the HIN to your dealer to "check" for the gas tank update, and if their cool enough you could ask who the original owners name is in the MPEM. You could then MAYBE start to track down the subsequent owners of said ski.
