Sensenich's 74CK Aluminum Propeller is designed for use on Continental A-65 through Continetal  C-90.  This propeller is also eligible for use on the Lycoming O-145.

It is available in a number of different pitches to match your aircraft's speed profile.   

This blade was designed for low horsepower Continental and Lycoming engines in aircraft with a speed range of 80 - 130 MPH.  We do not have a spinner available for this propeller.  Check with your aircraft manufacturer for a spinner for your particular aircraft. 

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.
