The T55-L7 powerplant creates high speed rotational energy, which is transferred through a gearbox at around 50% gear reduction to reduce propeller RPM.
These 30 foot, 6,800 lbs boats most often powered by a Lycoming T55-L7 turbine engine (used from the Vietnam era to the present day in the CH-47 Chinook military helicopter), which is capable of up to 3000 horsepower with current restrictions. This class of boat races in the United States, Canada, Australia and New Zealand.Īlthough bit of a misnomer as the boats aren't without limits, unlimited hydroplanes have much fewer restrictions than with limited hydroplane racing. The 23- to 26-foot craft are fast routinely attain speeds in excess of 170 miles per hour (273.5 km/h) in the straights. Grand Prix (GP) is a class of boats featuring supercharged big-block V8 piston engines producing as much as 1,500 horsepower. Limited hydroplane racing classes are inboard-engine powered boats that use high performance gasoline fuel.

Outboard Performance Craft hydroplanes (sometimes called "tunnel boats") are a different racing series of UIM and APBA outboard powerboat classes.

PRO outboard hydroplane hulls are constructed with lightweight wood, composite, and hybrid (wood/composite/aluminum) materials. Some hydroplane hull builders sponsor more than one team in a formula series circuit. Entry level classes for the PRO series classes are gasoline-fueled K-PRO (APBA sanctions only) and OSY-400 (sanctioned by both UIM and APBA.) International UIM teams have a formal crew that usually consists of family members, motor mechanic, hull builder sponsor, and owner/driver team in order to be successful at racing international F-125 through F-500 Circuit hydroplanes. K-PRO (an APBA entry class) is the only PRO hydroplane class running modified, recreational outboard motors all other PRO hydroplane classes use 2-stroke outboard motors designed and manufactured specifically for PRO circuit racing purposes. Investment costs are moderately high compared to similar APBA stock and modified outboard racing classes. 125cc through 1000cc PRO series hydroplanes are not entry level classes in outboard powerboat racing. All methanol-fueled and gasoline-fueled PRO racing outboard motors are direct drive (no gear reduction) and equipped with high performance, motorcycle racing style magneto ignition and carburetor systems. The faster classes of PRO hydroplanes (with straightaway speeds from around 75 to 120 miles per hour) use 2-cycle outboard motors running highly filtered methanol race fuel mixed with a pure castor or synthetic castor-based lubricating oil. PRO classes using 500cc and larger displacement racing motors must be equipped with an enclosed re-enforced capsule, a certified racing harness restraint system, and a self-contained oxygen system for the driver.

Professional F-series World Cup Title powerboat races are held at Europe, United States, and western Asia race site locations every year. The American Power Boat Association (APBA) sanction similar PRO class national title events in the United States. National powerboat racing teams compete for national and international titles in these hydroplane racing circuits. UIM's O-series hydroplane Formula Circuit racing events are some of the most prestigious Professional Racing Outboard (PRO) hydroplane events in the world.
International UIM F-125, F-250, F-350 and F-500 Circuit powerboat races are very popular in Europe, Asia, and the United States. The Union Internationale Motonautique (or "UIM", headquartered in Europe) sanctions many different hydroplane categories of hydroplane powerboat racing.
