Having bought an older, 2007 speedster with 15 hours on it, I found that these boats need work and as a buyer one needs to do their homework. Understand that before you can effectivelly go out in it service items have to be checked out ie: oil and anti freeze changed. I don;t trust what a previous owner has said about the supercharger, you should service it first. This way you can have piece of mind. Now unless this boat is dirt cheap I would have to take it to the water. If it were me, knowing what I know now I would take close look at the engine, run a compression test. Go look at it with your money in hand and ask for a water test, if the seller refuses then something is up. Better to be out gas money than having to pay for expense repairs soon after buying. I really like my Speedster and had to put money into it to get it up to my standards to operate. Like this boat you're considering, my boat was several hours away in another state, not very close to a boat ramp but I insisted on a water test and we did. Have you ever operated a jet powered PWC before?
