Listen to Aaron, save up more before you get a cheap ski. It doesnt have to be a round, but a ski thats in good condition and worth buying. Dont do what I did, I was in such a hurry, afraid I wouldnt find one by the time summer came so went for the project, which I enjoyed, except now I cant get it running the way it should, and nobody seems to be able to figure out whats up. With all the money Ive put into it, I could have easily bought a newer ski that works the way it should.
Im not saying Im sorry I did what I did, because I love my hull and what Ive done to it, but the motor is a different story. Im at the point now where Im replacing almost everything trying to find a problem, because nobody else can figure it out.
Just be patient and wait it out, get a job besides cutting grass, because $75 a week isnt that much, and that wont help at all through the winter where there is no grass to be cut. Maybe work out a deal with your parents where they chip in some for your birthday and christmas and stuff, then you have les to save. But dont be in a hurry and buy a ski thats going to cost more in maintenance and parts than if you would have bought a better ski to begin with.
