Motors For Fishermen! Knox Engines
The Atlantic Fisherman, a magazine for the fisheries business, got underway in 1921. Its third issue had this cover with this large advertisement for Knox Model G Valve-in-Head Motors. Starting from small two-stroke engines in 1901-2, Camden Anchor-Rockland Machine Company of Camden, Maine progressed into making larger engines, and also began to build engine powered boats.
These engines filled a growing demand for engine-powered lobster boats, but ultimately engines based on inexpensive automotive engines were to drive most of the marine engine specialists out of business.
