I'm going to suggest that this boat is Not a Steamer. Not much room for the boiler. The "V" Transom is more suggestive of a boat built around 1915. In this case...with an early gas engine..maybe one cylinder. Steam was going away.
The
Steamers usually had a "Fantail" stern: (Sweeping curve around the stern). Can't find a picture just yet.
The Antique Boat Museum in Clayton, NY has as their Logo boat the
"Wild Goose" with the "V" transom. It is 40 feet long and 7 feet wide. (1915) She started out with a 150HP Sterling straight 6 cylinder. Currently with a modern V8.
