74DM7S14

Sensenich’s 74DM7S14 Aluminum Propeller is designed for use as an STC propeller on the Cessna 172 I-P models using the Lycoming O-320 engine. It is available in a number of different pitches to match your aircraft’s speed profile.  This propeller comes with a  3.5″ spacer, and is drilled for 7/16″ attaching bolts.  This blade was designed for medium horsepower Lycoming engines in aircraft with a speed range of 120 – 170 MPH.   Check with your aircraft manufacturer for a spinner for your particular aircraft.  NOTE: This STC is not approved in all countries. Please contact Sensenich before ordering. All Sensenich aluminum propellers are manufactured from 2025 forged aluminum.  The propellers are CNC machined and hand-finished to very tight tolerances.  Each propeller then goes through a rigid 56 point inspection to assure you of the highest quality, most problem free propeller available.  All aluminum propellers are vibration tested before being approved for use on any engine.
