The Continental O-300 and the C145 are a family of air-cooled flat-6 aircraft piston engines built by Teledyne Continental Motors.[1]

First produced in 1947, versions were still in production since 2004Template:Dated maintenance category (articles)Script error: No such module "Check for unknown parameters".. It was produced under licence in the United Kingdom by Rolls-Royce in the 1960s.

Development

The C-145 was developed from the Script error: No such module "convert". C-125 engine. Both powerplants share the same crankcase, although the C-145 produces an additional Script error: No such module "convert". through a longer piston stroke, higher compression ratio of 7.0:1 and different carburetor jetting.[1]

The O-300 is a modernized C-145 and retains the same weight, dimensions, bore, stroke, compression ratio, displacement and output power of the earlier engine.[1]

GO-300

The GO-300 employs a reduction gearbox, so that the engine turns at 3200 rpm to produce a propeller rpm of 2400. The GO-300 produces Script error: No such module "convert". whereas the ungeared O-300 produces Script error: No such module "convert"..[1]

The GO-300 engine has a TBO (Time Between Overhaul) of 1200 hours, while 1800 hours is the standard for ungeared O-300 engines. The GO-300 engine suffered reliability problems as a result of pilots mishandling the engine and operating it at too low an engine rpm. This caused the Cessna Skylark to develop a poor reputation for engine reliability. Many Skylarks flying today have been converted to different, larger-displacement, direct-drive engines.[2]
