Hello I have finally saved up enough to buy a JetSki for myself and have stumbled upon a deal where someone is selling a 1999 Tigershark 770 TSR with trailer and cover for 2000. I have not looked at it yet and am going to be taking a friend who is a mechanic out to look at this ski tomorrow morning. I was wondering what the general consensus was on this model of ski. From what I have read most like the 770 TSR's engine. Thanks for any help and I cannot wait to join the PWC community!
