I am goin to purchase a 96 yamaha 1100. They're asking $2500 includes trailer. They've had it professionally winterized every year and it was just gone through last fall by a shop and they said everything looked good. Supposed to have between 110-130 hours. Only thing not checked was the pump. They also said that it use to do 64 but that little speed sensor thing on the bottom lost a couple cogs and now it only tells you half the speed. I am new to jet skis so I am looking for any help or opinions.
