It is available in a number of different pitches to match your aircraft’s speed profile.  This propeller comes without a spacer and is drilled for 3/8″ attaching bolts.

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.
