This is the later style transom screw clamp assembly - the pressure washer is attached to the screw by a special shoulder bolt eliminating the pain of that old clip that was used in the 1950's and 60's.  This will fit a crap-ton of Johnson and Evinrude outboards up to 35 hp* including models that originally had the PITA assembly on them. Shipping is reasonable via fast and tracked 1st Class Parcel. Thanks for looking. 

*Screw diameter is 5/8" - some older low-hp motors used a 1/2" diameter clamp bolt so this item won't fit those.
