Yes I beleive it is. The outboard was a Featherweight. They hhave a shorter than standard shaft length so ideal for small dinghies with little freeboard but before 1967 were called Forty Minus.
The Forty Minus / Featherweight also has a smaller propeller and a different carb (maybe just the jetting) to cut down power a bit. The powerhead is otherwise the same as the Forty.
