Hi, I'm buying a 1998 Sea Doo sportster 1800 for $6000. The boat is in great shape and has never been in salwater. Is this a good buy? I was told by someone to stay away from that year and model cause they said it was a "pig" lol and not fast at all. Is it true or should I buy it? Thanks in advance and this is a great forum you guy's got here.
