Used to Mount Wood Propellers
DescriptionThese bolts are not for Sensenich Propellers. Sensenich Propellers are supplied w/bolts.
Includes washers and self-locking nuts. Length based on typical prop thickness of 4 3/8"-4 1/2".
There are two styles of prop extensions and each style requires a different type of prop bolt. The 4" spool extension uses a 3/8" bolt with an O-320 or a 1/2" bolt with an O-360 engine. The 2 1/4" cylindrical extension uses a bolt through the crush plate, prop, extension and into the engine crank flange. Not available in 3/8". If your crank requires 3/8", the crankshaft bushings must be replaced with 7/16" bushings (not available in this catalog). The O-360 uses 1/2".
Priced as a set of six.
