I have the chance to buy a 2000 Yamaha GP800 for $2500 with trailer. Ski is in great shape and runs like a top in and out of water. Can someone give me some info on these skis? Is the price right? Also are the 800's dependable? What would be the top speed on one of these? Oh by the way it has 10 hours on rebuilt motor, and I have bought ski's from this guy before he works on them himself and really knows his stuff. Any help is greatly appreciated!
