American manufacturer of diesel engines based in Oakland, California. The company was created in 1916 when two early gasoline engine companies combined to manufacture diesel engines, following the expiration of Rudolph Diesel's patents.
The company made diesels for tugboats, fishing boats, coasters, yachts, light-vessels, and other ships. The company produced engines in a variety of sizes and ratings, from a 2-cylinder model that generated 30 horsepower (22 kW) to an 8-cylinder model that generated 600 horsepower (450 kW).
