77.9 hours on ski. less than 20 hours on motor. EBT engine. Low compression on cylinder 1.  I purchased ski a few months ago and had carbs rebuilt, all oil lines replaced, new seat covers installed, new battery, D plate, and a few other items to get it ready for summer. I am the second owner and have paper work on EBT engine swap and all original paper work from original owner when purchased new. I also have receipts on the parts. ski still runs but does not have full power. I have a boat that takes most of my free time now and do no wish to mess with the ski. Ski is in my name. Will come with bill of sale. I initially thought i lost spark on number 1 cylinder and purchased a coil. had it looked at was told the #1 cylinder was low on compression. Questions welcome.
