I am not real familiar with pwcs i used to own a pair of yamahas about 8 yrs ago but i have a friend at work that has a 97 tigershark for sale for 1800.00 it has sat for 3 yrs and he bought it new. He took it to the dealer to be tuned from sitting so long and it runs out great my question is how are tigersharks?? i know names like yamaha and sea-doo etc but tigershark is one i dont see a lot are they prone to having problems??
