| One of Kermath’s additions to last year’s successful Sea Chief Model is this 6-cylinder engine developing 96 hp. at 3600 r.p.m. New Kermath Specials For 1940 Three hitherto unannounced engines are being shown by the Kermath Manufacturing Co., of Detroit, along with its standard lines of gasoline and Diesel marine engines. One of these, the Sea Mate Special, is, as its name implies, an enlargement of the former popular Sea Mate unit. While the external appearance greatly resembles the Sea Mate, it is an entirely new unit, developed for higher speed work, being fitted for this purpose with a seven-bearing counterweighted crankshaft. The motor is compact, measuring but 56 3/16” over all in the direct-driven unit, and 59 inches over all with the addition of the Upton reverse and reduction gear which is a specialty of the Kermath company. A 6-cylinder job, with piston displacement of 404 cubic inches and with 4 1/4” by 4 3/4” bore and stroke, the Sea Mate Special develops 155 hp. at 3000 r.p.m. The success of Kermath’s mid-season model, the Sea Chief 8, has encouraged the company to bring out two additional sizes of motors of similar characteristics. One of them, the Sea Chief 8 Special, is an eight-in-line, with a bore of 3 1/4” and a stroke of 3 3/4”, and with 249 cubic inch displacement, which develops 110 hp. at 3600 propeller revolutions on direct drive and the same horse power at 1800 propeller revolutions with the Upton reverse and reduction gear. The other member of the series is the Sea Chief 6, with bore and stroke of 3 7/16” and 4”, the pistons displacing 223 cubic inches and the motor developing 96 hp. at 3600 r.p.m. Among the features of the Sea Chief 8 Special to which the manufacturer calls particular attention are the following: Harmonic vibration dampener and balancer for smooth operation at all speeds; large oil cooler, which maintains oil at the proper temperature for great economy; Fram oil filter; full length water jackets completely surrounding each cylinder; famous Kermath Temporator which controls water temperatures and further improves operating efficiency; and high-turbulence, flame-hardened machined cylinder heads. The Sea Chief 6 is shown with the latest Kermath development, the Centriflow fresh water cooling system. This system, although a new development, is a lineal descendant of the fresh water cooling system originally developed by Kermath for motors supplied to the United States Navy. It will be put into quantity production for the 1940 season on the Sea Chief 6, the Sea Chief 8 and Sea Chief 8 Special, as well as on the V-8, the Sea Mercury and the Sea Zephyr models. Fairbanks-Morse Exhibit in Block H In its usual space in Block H at the Palace, Fairbanks, Morse & Co., of Chicago, is displaying five models, including propulsion motors and generating sets. These engines comprise a Model 35, 8” by 10 1/2”, 8-cylinder Diesel; a Model 36 8-cylinder propulsion engine with 2:1 reduction gear; a 2-cylinder Model 42 marine generating set which develops 125-volt direct current; a 5 hp. 32-volt generating set, Model 45, and a 10 hp. Model 45 propulsion Diesel with Joe’s gear and direct drive. The “45” is a new Fairbanks-Morse engine developed for auxiliary service in either steam or Diesel boats, and is built in 1- and 2-cylinder sizes to give 5 and 10 hp. respectively. The 2-cylinder job is of “V” type and is available for propulsion service in small boats. This engine, with 3 1/2” bore and 4 3/4” stroke, operates at 1200 r.p.m. and is conservatively rated as to horse power. This new Fairbanks-Morse engine is of the 4-cycle full Diesel type, with solid injection and full pressure lubrication, and is precision built. The 2-cylinder model has both connecting rods on a single crankpin, side by side, and is constructed with removable wet type cylinder liners. Bosch type injection pumps and pintle type injection nozzles of the individual type are used. The generating units are produced with standard marine type of drip proof construction and with moisture proof and corrosion resisting fittings. The propulsion units are arranged with the flywheel forward and are fitted with Joe’s 1:1 reverse gear. They may be started readily by hand. The Kermath Sea Chief “Eight” Special, with fresh water cooling system. It develops 110 hp. on either direct drive or with reduction gear. | ||
