ROTAX – 300003003 – Gearbox Type C – I-3.00

Genuine Rotax Type C reduction gearbox designed for use in Rotax aircraft engines. This gearbox reduces engine crankshaft speed to an optimal propeller RPM ratio, improving propeller efficiency, thrust performance, and overall engine-propeller matching. The I-3.00 designation indicates a 3.00:1 reduction ratio, allowing the propeller to operate at lower RPM while the engine runs at higher, more efficient speeds.

This gearbox assembly is engineered for certified aviation use and incorporates precision gearing, damping elements, and lubrication systems designed to handle continuous aircraft operational loads and vibration conditions.

Application: Rotax aircraft engines, propeller reduction drive systems, certified engine gearbox replacement and overhaul installations, light aircraft propulsion systems
Function: Reduces engine output speed by a 3.00:1 ratio to optimize propeller efficiency, torque delivery, and reduce propeller tip speed for improved aerodynamic performance and noise reduction
Gear Ratio: 3.00:1 (I-3.00 Type C gearbox)
