I had finally just bought a jet ski (my family and i) and im going to be the one taking care of it. We have a 2005 Yamaha VX Deluxe (red), used and i want to know what should i do to keep it in good condition, and my other question was for the yamaha it has water spitting out the back i dont know what thats called but is there a way to stop it from doing that so we can pull a wakeboarder or a kneeboarder? Thank you.
