PROPULSION UPDATE Detroit Diesel Introduces Three New High-Speed Engines —Free Brochures Available— Detroit Diesel Corporation re- cently introduced three new genera- tion high-speed engines for the pas- senger boat, pleasure craft and ma- rine market—the 16V-149TI, 6- 71TI and 3000 Series. til Detroit Diesel Marine 16V-149TI The 16V-149TI is a 16-cylinder, 149-cubic-inch-per-cylinder engine capable of producing 2,200 bhp at 2,100 rpm. The 149 engine was first intro- duced in 1967. Over 15,000 Series 149 engines are in service in genera- tor sets, and marine and other appli- cations. The engine is designed with a twin-section, wet-linered cylinder block, two-piece overhead camshaft, a unit fuel-injection system, individ- ual cylinder heads, iron crosshead pistons, crankcase access plates, a two-piece crankshaft and quad water-cooled exhaust manifolds and turbochargers. Detroit Di«sal Mann* 6-71TI The new 6-71 is a six-cylinder, 71- cubic-inch-per-cylinder engine available in ratings of 485 bhp at 2,500 rpm and 450 bhp at 2,500 rpm. Introduced in 1938, the new re- engineered marine 6-71 engine in- corporates design input from De- troit Diesel distributors servicing the marine industry. The marinized engine consists of over 80 newly designed components with a total investment of $800,000. The turbocharged and inter- cooled engine is designed to be com- pact, and features a high capacity 24-plate oil cooler, water-cooled ex- haust system, a maxi-bypass blower, a new cooling system, crankcase breather collection system, a unit fuel injection system and engine controls, and low-speed perform- ance enhancements. Detroit Diesel Marine 3000 Series The 3000 Series marine engine represents the first product offered from the joint collaboration be- tween Detroit Diesel Corporation and Perkins Engine Company, Ltd. The 3000 Series is a pre-production marine engine which will be avail- able in limited quantities beginning this fall. The 3000 Series is a direct injec- tion, four-cycle, eight-cylinder Vee configuration engine and is rated at 800 bhp at 2,400 rpm. The engine fits into the Detroit Diesel marine engine line-up, thus strengthening DDC's marine engine offering. Turbocharged and intercooled, the engine has a freshwater heat exchanger, freshwater cooled ex- haust manifolds and seawater charge cooling. Oil is freshwater cooled and the engine's filters are "spin-on" for ease of maintenance. Furthermore, DDC also an- nounced it would market a full line of marine gears for all Detroit Diesel pleasure craft engines. The gears will be manufactured for DDC un- der an agreement with Twin Disc Corporation. Headquartered in Racine, Wis., Twin Disc is a leading independent designer and manufacturer of heavy-duty off-highway power transmission equipment. Founded in 1918 to manufacture farm tractor clutches, now Twin Disc's product line consists of hydraulic torque converters; power-shift transmis- sions; marine transmissions; univer- sal joints; gas turbine starting drives; power take-offs; mechanical, hydraulic and pneumatic clutches; fluid couplings; planetary gear re- duction equipment and control sys- tems. The new marine gear and engine program will provide benefits to both boatbuilders and boat owners. Working together with Twin Disc, Detroit Diesel will now be able to offer the boatbuilder a complete power package that provides the op- timum match of engine and gear suited to the particular application. The match will optimize perform- ance, durability and reliability and gives the boatbuilder a cost-effec- tive package. The boat owner will be able to obtain service for either the engine or the marine gear at the same ser- vice location. All authorized Detroit Diesel Corporation distributors and marine dealers will have the techni- cal training and replacement parts necessary to perform marine gear maintenance and repairs. The agreement provides a two- year parts and labor warranty ad- ministered entirely by Detroit Die- sel Corporation. Extended service coverage will also be available. Tra- ditionally, gear and engine manu- facturers administer their own war- ranty, with varying terms of dura- tion and coverage.
