Friend of mine just picked up his first pwc, seeing how he has a 07 kawasaki zx-10 he decided to stay kawi and got a 98 zxi 1100. This was his 2nd choice next to the ultra 150 1200cc in the budget. So got what we could find and its a yellow 98 zxi 1100. Wanting to know general info on this thing, what are known problems, whats are good mods, what should be paid close attention too, general stock specs etc etc, anyhing would be great. See some info on a model called stx but not sure on the differences. Is this a good reliable boat? No hr meter but guy claims it got a new top end 3 yrs ago. Fires right up and motor looks clean. Thanks for any help!
