My kid and I both rode Kawasaki's. I've since sold mine but his is still alive and running strong after five years.... Service is important on them. If they're going to sit for the winter, make sure you follow the manufacturer's recomendations for winterizing.... Having rode most everything that came out new for a number of years, got to say IMO the Kawasaki's are the smoothest hulls across the water but that big 4 stroke Yamaha is fast and very good handling!!!! Just had one out to play with last weekend....
