Remarks: Could not locate this engine in MILL C-2. A review of MSM marine engine accession listings going back to 1994 did not turn up this engine. Once listed under Accession Number 1989.32.1f, but could not find the source of this number. About 500, 52-pound, 3-hp Gray Gearless outboards were produced between 1914 and 1917, according to Peter Hunn's "The Outboard Book". Gears were eliminated by using a flexible drive shaft rotating within a tube bent to about 90 degrees.
