for operation on automobile gasoline on the basis of Supplemental Type Certificates. While the C90 is approved for takeoff power of 95 horsepower (71 kW) for five minutes, the designation is derived from its continuous power rating of 90 hp (67 kW). As noted above, certain models of the C90 replace the usual carburetor with a fuel injection system. In addition, there are models which provide for the installation of a controllable-pitch propeller and one, the C90-12FP, designed for a pusher configuration installation. While having slightly less horsepower than the O-200, many floatplane operators prefer the performance of the C90 over the O-200, due to its higher torque at lower rpm. This is primarily due to the C90's camshaft design. The C90 is also known by its military designation of O-205. The O-200 is an updated and upgraded version of the engine, achieving increased power of 100 hp (75 kW) as a result of higher maximum rpm. The standard and most common model of the engine is the O-200-A; the -B model is designed for a pusher installation, the -C model provides for the installation of a controllable-pitch propeller, and the -D model is a lower-weight version designed for light-sport aircraft. Operational history An engine designated the IOL-200, an O-200 variant modified with fuel injection and liquid cooling, powered the 1986 nonstop, non-refueled global circumnavigation flight of the Rutan Voyager. The 110-horsepower (82 kW) IOL-200, also referred to as the Voyager 200, was the rear engine and—unlike the forward engine, another modified engine, a Continental O-240 —ran throughout the entire nine-day flight save for a four-minute shutdown due to a fuel problem. Formula One racer Sharp Nemesis, designed and flown by Jon Sharp, was powered by a 'stock' O-200. Between 1991 and 1999, the aircraft won 45 of the 48 events in which it was entered, as well as winning three Louis Blèriot medals, four Pulitzer Trophies, and setting 16 speed records in its class. In one of those records, Nemesis was clocked at more than 290 mph (467 km/h). By contrast, the O-200 powered Legend Cub cruises at 95 mph (152.9 km/h).
