This is an extremely custom built racing jet ski. Built off a 2003 Yamaha GP 1300 R. Was professionally raced back in the day. Has had about $40,000 worth of parts and labor installed on it only thing that is stock is the hull and part of the original engine block. Everything else is extremely custom. And high-performance and high-quality aftermarket parts. Was on the water a few years ago and had a water leak. It runs on 100 ethanol. Put a battery at last week and it starts up. If I remember right compression is over 200psi. Only asking 2500 the machine alone. Engine could easily be dropped into a jet boat or sick project.
