Japanese Pro Runabout champion of 2010 Hajime Isahai came to Havasu this year and looked fast on his specially prepared lightweight Ultra. The particular craft featured lots of tricky parts (pump, trim tabs, etc.). Engine wise it was an exception among the American opposition since it was equipped with a Rotrex Supercharger that featured a watercooled oil cooler, tensioner, bracket and pulley. The kit is available at the moment by AMC Racing in Japan. Congratulate to the whole Team for their exceptional effort to design something different that gave them good results.
