Fred Thorne, Deere's director of engine marketing, explained that the company's decision to enter this market is based on several factors including Deere's experience in de- signing and manufacturing reliable, durable, heavy-duty diesel engines. "We plan to leverage our exper- tise and success in heavy-duty die- sels to help address the types of problems and concerns voiced by marine engine users we've inter- viewed," said Mr. Thorne. He also cited a moderate rate of growth in the market and requests from Deere engine distributors as ther reasons for the company's action. Deere plans to begin testing its marine engines in fishing boats and a variety of workboats this fall. A network of marine servicing dealers is being established to support the engines. Mr. Thorne emphasized that these dealers will receive com- prehensive training on Deere ma- rine engines and will be served by the John Deere parts system—a computerized network of 11 region- al depots supported by a central parts distribution center near Deere's corporate headquarters in Moline, 111. After showing the two prototype engines at various shows (a 240-hp, 7.6-liter, aftercooled, six-cylinder diesel with a Twin Disc marine gear and a 80-hp, 3.9-liter, four-cylinder diesel attached to a 20-kw Lima generator), designs have been re- vised to reflect customer sugges- tions. "We want to ensure these engines address the specific needs of the commercial marine market. And the best way to accomplish that is to lis- ten to those who will depend on these engines for their livelihoods," said Mr. Thorne. "Equally impor- tant is the feedback we receive from commercial boat manufacturers." Although the company's an- nouncement marks Deere's official entry into the marine business, John Deere engine distributors have been sending marinized engines to work on the water for several years. This means Deere will enter the marine market with several experienced marine distributors. Deere also brings 40 years of diesel design and manufacturing to the marine market. KRUPP MAK Circle 65 on Reader Service Card Krupp MaK diesel engines have been utilized in a wide range of pro- pulsion and auxiliary power applica- tions, from pushboats operating on the inland waterways to large luxu- rious oceangoing cruise ships. When American Commercial Barge Lines (ACBL), one of the largest inland barge operators in the U.S., decided to refit new engines aboard its pushboat M/V Bill Elm- er, three new Krupp MaK 6M 453 engines were selected. Since com- missioning, the three diesels, each rated at 1,800 kw (2,414 hp) at 600 rpm, have run for 45,000 hours in heavy fixed-pitch propeller opera- tion, with speed reduction and fre- quent load changes. July, 1990 According to Krupp MaK, upon their latest overhaul, the condition of wear on the parts confirmed the excellent heavy oil capabilities of the model M 453 engines. The pis- ton crowns were exchanged after 36,500 hours, although their re- placement was not required. After 25,000 hours, the residual chromium layer still existed on the piston ring and the liners showed a wear rate of 0.01 mm per 1,000 hours of opera- tion. In a recently delivered 220-foot Canadian trawler, the Cape Adair, Krupp MaK supplied the entire propulsion and auxiliary power package. The economic and flexible propulsion and power package in- cluded a model 9M 453C, rated at 3,300 kw (4,425 hp) at 600 rpm, for main propulsion and a model 6M 332 diesel, rated at 1,280 kw at 900 rpm, for auxiliary power. The flexi- ble system has three operating modes—(1) in sea operation, with- out the refrigeration system, ship's power is supplied by the shaft-driv- en generator (PTO); (2) in sea and trawling operation, ship's power is supplied by the shaft driven genera- tor (PTO) and power is supplied to the refrigeration system by the die- sel auxiliary unit; and (3) emergency operation with diesel-electric pro- pulsion, power is supplied for pro- pulsion (and the refrigeration sys- (continued) GE and ALCO Partners In Power When ALCO, a leading designer and manufacturer of high horsepower diesel engines, became a member of the GE family, they joined one of the world's most compre- hensive service networks.
