Unlimited Hydroplane Testing on Columbia River This Saturday [VIDEO]

Unlimited Hydroplane fans will get to see some of the boats two months early as they scream down the Columbia River this Saturday. Jon Zimmerman and Jones Racing will bring their U-9 Unlimited Hydroplane to test, this Saturday, May 31, from 9:00 a.m. to 5:00 p.m.  A few others boats, such as the Specialty Mobility 1-liter hydro, driven by the Tri-Cities' own Josh Culver will also take to the course for pre-season testing.

Boaters be advised, the river will be closed while hydroplanes are on the water.  The HAPO Columbia Cup and Airshow  is July 25-27 - get tickets and schedules HERE.
