Just want to thank everyone in advance for their help. I have a guy that's offering to sell me a 2007 seadoo gti se155 for $6500 but I don't really know much about jetski. Seadoo looks to be in very good body condition with a few minor scratches and has 51 hours on it. Seadoo just had tune up done about a month ago and a new propeller and O ring were installed as well. Any information on this seadoo and value would help. Thanks again.
