The 1999 Sea Doo Challenger 1800 is a great boat, it's just the right size for what it was intended to do , it's has good speed over 50 mph, very good on fuel (I never used over 1 tankful in a day) It turns on a dime, and it can pull a house. My Challenger needs 1 engine , I replaced the port side with an SBT Rebuilt and about 15hrs later the other one went. You can get the SBT Rebuilt with a 1 year foolproof warranty. You need a core which I have.I have owned this boat since 2003 and really enjoyed using it. I have always kept it in the garage , the hull and gelcoat are in excellent condition. The seats have some cracks from the sun , they were there when I got the boat.. The cushion that goes on the engine cover is missing (they blow off on the highway). It comes with it's original trailer (free), ( Dual) Am/Fm CD Player , Fairly new Bimini Top with a 6"x6" hole that was repaired.
