2.5-Liter Hydroplanes

The Tri-City Water Follies is delighted to announce that the Columbia Cup/Over the River Air Show will welcome 2.5-liter class hydroplanes to its lineup of exciting boat racing on the Columbia River July 26 โ€“ 28, 2024!ย 

2.5 Litre Stock hydroplanes (“S” class) race to 100-plus mph, using 145 horsepower marine-based 2000 and 2300 Ford engines. S-boats offer very exciting side-by-side racing at a reasonable cost. Driving skill is paramount here, and driver development is inevitable, making this class an excellent stepping stone to bigger, higher-powered classes.
