A 100cuci register is a unit in a vintage outboard motor that indicates its displacement in cubic inches, a classic measure in older engines. It refers to the total volume of all cylinders, typically found in mid-century Evinrude or Johnson models, delivering around 20 horsepower. Enthusiasts often search for this specification when restoring or identifying antique outboards, as it helps determine power output and compatibility with boats from that era.
