I'm a long time Seadoo owner, but I have only ever had 2-strokes.  I now live on a quiet, calm lake and am tired of the high fuel usage and constant maintenance of my 20 plus year old skis.  I am looking to buy a Spark.  I know I want IBR and 3 up.  Can I get some other basic information about years and things to look out for when buying used?  Thanks so much!
