Nice matching number Green and Gold Mark 20H.  This engine was restored sometime before we purchased it.  Some of the Gold paint we feel is the incorrect shade but other wise the engine is quite nice.  The fuel plug is home made but functional. The thumb screw are bent slightly.  It has the original fuel filter and Carter Model N carb.  The throttle hook up appears original and is in good shape. The lower unit is the later style deep skeg single hole that Mercury came out with in 1956.  There is a hole drilled in the upper cowl handle to access the recoil sheave shaft, which was done by many racers to facilitate quicker repair. We quote 10 days for shipping since want to have time to construct a proper wooden crate.
