Continental O-300

From Wikipedia, the free encyclopedia

The Continental O-300 originally known as the C-145 are a family of air-cooled flat-6 piston engines for aircraft. First produced in 1947, versions are still in production today. It was produced under licence in the United Kingdom by Rolls-Royce in the 1960s.

[edit] Variants

[edit] GO-300

This engine drove the propeller through a reducing gearbox, so that the engine turned at 3200 rpm to turn the propeller at 2400 rpm.

The GO-300 engine had a TBO (Time Between Overhaul) of only 1200 hours[1], while 2000 hours is considered standard for most light piston-engined aircraft. The GO-300 engine also suffered reliability problems and helped the Cessna Skylark develop a poor reputation, although many Skylarks flying today have been converted to normal engines where the crankshaft drives the propeller directly. The reputation of this engine may not have been deserved, since the problems associated with it could have been the result of pilots who were familiar with more conventional arrangements simply not operating the engine correctly.
