I have an extremely great pair of 2005 Seadoo 3D's with only about 50 hours a piece. These are 787cc two stroke extremely quickly, extremely enjoyable. I purchased these machines brand name new in 2007 from the dealer. I have used them personally for the last 7 years and have actually just taken them out about 2-3 times per period, which here in Utah is June July and August. Never made use of in salt water.The just thing I have actually had to change were the starter relays. Besides that They have actually been extremely well preserved and winterized each year.
