The Franklin O-300 (company designation 6AC-298) was an American air-cooled aircraft engine of the early 1940s. The engine was of six-cylinder, horizontally-opposed layout and displaced {{convert|300|cuin|L|abbr=on|0}}. The power output ranged between {{convert|130|hp|kW|abbr=on|0}} and {{convert|175|hp|kW|abbr=on|0}} depending on variant. The 6ACG-298 featured a geared propeller drive. An enlarged displacement version was known as the O-315, 6A3 or 6AL-315. VariantsO-300- 6AC-298
