Sensenich's 74DM7 Aluminum Propeller is designed for use on Lycoming O-290 and O-320 engines from 125 to 165 Horsepower.  This propeller is used on aircraft such as Cessna 172's and some Maule Aircraft.
It is available in a number of different pitches to match your aircraft's speed profile.  This propeller is available with different length spacers 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.  We have multiple spinners available for this propeller. 
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.
