The CAMit 3300 is an Australian lightweight four-stroke, 6-cylinder, horizontally-opposed air-cooled aircraft engine. Direct drive and using a solid-lifter valvetrain, the 3300 develops at 3300rpm. The engine was manufactured by CAMit Pty Ltd, of Bundaberg,

, Australia. CAMit has manufactured engines for Jabiru since the Italian-sourced engines used by Jabiru became unavailable in 1991. After receiving requests for and producing aftermarket Jabiru engine parts, CAMit went on to produce whole engines incorporating these modifications in late 2013. Many parts are interchangeable with the original components from

engine. However, in terms of component design, lubrication, valve train operation and metallurgy, the CAE engine is a completely different motor to the Jabiru design. The CAMit series of engines are classed as Experimental. Each serial number includes 'SLRE', designating 'Solid-Lifter Revised Experimental'. CAMit Pty Ltd ceased operations and was placed in receivership in October 2016.

(CASA) imposed restrictions on all aircraft powered by Jabiru engines "in response to power-related problems involving engines manufactured by Jabiru Aircraft Pty Ltd (Jabiru)". It was stated in ''Sport Pilot'' magazine shortly after this that "the CAMIT icengine is not subject to the Jabiru operational limitations described in 292/14, because the engine is not manufactured by a person under licence from, or under a contract with, Jabiru." As of July 1, 2016, these restrictions were lifted for "most Jabiru-powered aircraft in Australia. Stock Jabiru engines that are maintained in strict accordance with Jabiru service bulletins and maintenance instructions are no longer affected by the limitations, which were issued in late 2014."
