           This is an Optional Long Prop Nut and Washer Set for the
                O.S. Max .60FP, .65LA, .61FX, .91FX Engines.

FEATURES: Metal construction.
          For use where an extra thick propeller boss (center) and/or spinner
            backplate does not leave enough threads for a standard propeller
            nut to tighten down onto the propeller.  This nut has an extension
            that goes through the propeller and then extends out past the end
            of the crankshaft with a hex nut for tightening.
          This also helps keep the propeller on the engine in the case of
            backfiring or detonation.
          This can also be used on most engines that have 5/16"- 24 threading.
