The Turbomeca Marboré is a small turbojet engine that was produced by Turbomeca from the 1950s into the 1970s. The most popular uses of this engine were in the Fouga CM.170 Magister and the Morane-Saulnier MS.760 Paris. It was also licensed for production in the United States as the Teledyne CAE J69.Gunston 1989, p.169. In Spain the Turbomeca model Marboré II was manufactured by ENMASA under license with the name Marboré M21.

The original Marboré, as well as Marboré III, IV, and V were not produced in significant numbers. A typical weight for this series of engines is {{convert|140|kg|abbr=on}}. Fuel consumption is {{convert|720|L/h|abbr=on}} on the Marboré VI at {{convert|4500|m|abbr=on}}, as compared to {{convert|520|L/h|abbr=on}} on Marboré II engines (same altitude), as well as an increase of fuel consumption of 27% and a decrease in cruise range capabilities.CM-170 Flight Tests, Airplane Cruise Performance Charts, and Aircraft Flight Manuals

Variants

;Marboré I:Prototypes and test examples

;Marboré II:The first major production version was the Marboré II, which had a maximum thrust of {{convert|3.9|kN|abbr=on}} at 22,500 rpm. In its most basic form, it is a single-spool, centrifugal compressor turbojet. Fuel consumption was rated at {{convert|410|L/h|abbr=on}}. Variations include military or civilian aircraft, oil tank design, auxiliary equipment, and exhaust pipe configuration. Some variants also included one axial stage compressor for additional performance. The engine dimensions differ depending on the variant, auxiliary components and mounting configurations.

;Marboré VI:The Marboré VI series were slightly more powerful at {{convert|4.8|kN|abbr=on}} instead of {{convert|3.9|kN|abbr=on}}. Fuel consumption was only slightly higher at {{convert|450|L/h|abbr=on}}. This was a 23% increase in thrust with slightly more than a 9% increase in fuel consumption. As a result, the VI series were used to re-engine many II-series powered aircraft, and Marboré II engines became available at discount prices.
