| Left, exhibited for the first time at the 1940 Show is this 2-cylinder 2-cycle marine Diesel electric generating set, one of the U. S. Motors Corporation's new products. Below is the 10 kw. Diesel set typical of the Series 5 to 60 kw. in sizes ranging from 10 to 80 kw. capacity at 900 and 1200 revolutions. All U. S. Motors Diesel models are available for fresh water cooling, which is recommended by the makers not only for salt water areas but for those lake and river regions where chemicals or other undesirable substances are present in the water. Models of the U. S. gasoline line are also on display, both in propulsion and generating units, and the small 1- and 3-cylinder Falcon marine engines that have enjoyed so many years of popularity are continued as heretofore. To meet the needs of owners of cottages and small summer homes, the company is showing a 400-watt, 110-volt A.C. unit and an 800-watt fully automatic A.C. unit. Both units have air-cooled engines and are intended to take care of summer house lighting requirements with economy and efficiency. The Smith-Meeker Engineering Co., of New York and Philadelphia, is also showing the United States Motors 2-cylinder Diesel-electric plant, along with representative gasoline units. uous sustained service. For the technically minded: the engine is equipped with a full pressure oil pump, oil cooler and oil filter; with a crankcase capacity of 4 gallons; individual injection pumps; single orifice injection valves, and a fuel filter. The standard starting method is by independent 10 hp. 2-cylinder gasoline engine, but electric starting is available with or without the gasoline starting system. In addition to the “D4400,” the exhibit includes the V-8, 135 hp., model D17000; the 6-cylinder, 100 hp., D13000; and the 6-cylinder, 55 hp., D4600. Each of the engines is completely equipped and ready for installation with only five connections to be made. In short, all you have to do is stick the engine in the boat, connect exhaust to atmosphere, sea water suction to raw water line, heat exchanger outlet to overboard discharge, fuel oil line to main tank, align and connect thrust bearing shaft to propeller shaft, turn her over and get under way! In addition to the four engines in the exhibit, there is a selection of enlarged action photographs and other illustrative material. Universal Introduces Retractable Drive for Fishing The Universal Motor Company of Oshkosh, Wis., enjoys an enviable reputation for enterprise in the design and construction of marine engines and their equipment. This company’s 1940 exhibit at the Motor Boat Show includes not only the new retractable drive, noted in the heading, but three new engine models as well as some of the popular models from previous years. In all, Universal is offering ten separate series of engines for 1940, each of a different piston displacement and, in addition, the special 91- and 135-cubic-inch class racing models. The retractable drive is a new contribution to the boating and fishing industry and was originally designed to save time and cut cost for seine fishermen. The retractable principle is accomplished by building a rectangular well into the hull, slightly offset from the keel. The lower gear housing, attached to a base plate, can be moved up and down in this well. Lifting racks are mounted at each of the four corners of Caterpillar Diesels One may wonder what a famous builder of tractors has to do with a Motor Boat Show. Actually, the Caterpillar Tractor Company builds a number of Diesel engines entirely for marine use, and 660 square feet of floor space on the main floor of the Grand Central Palace, filled with these engines, goes to prove it. Emphasis in the Caterpillar exhibit is on the new 35 hp. 4-cylinder job. This model, known as “Model D4400” delivers 35 hp. at 1500 r.p.m. for contin- The Caterpillar D4400 marine Diesel engine develops 35 hp. at 1500 r.p.m. Its four cylinders are of 4¼” bore and 5½” stroke.
