[1] Enterprise, the second steamer of this name to operate on the Willamette, was launched in November 1863, and ran independently for a short time under George Pease.

Enterprise was 120 or 125 feet long, exclusive of the extension of the main deck over the stern, called the fantail, on which the stern-wheel was mounted.

[2] Enterprise was equipped with twin steam engines, single-cylinder, horizontally mounted, each with bore of 13 in (330.2 mm) and stroke of 4 ft (1.22 m), 13 nominal horsepower.

[2] Soon after Enterprise was launched, an accommodation was reached with the dominant steamer line on the Willamette, the People's Transportation Company, after which Pease remained in command for over two years.

[1] As of October 27, 1866, steamers of the People’s Transportation Company, Enterprise, Echo, and Active departed Oregon City every Monday and Thursday for Salem, Albany, and Corvallis.

[4] In September 1867, the steamers Enterprise and Echo were reported to be able to make regular trips to Albany because navigation obstacles in the river had been removed.
