Demonstrations made on appointment, MARINE REVIEW There is a difference N selecting a Diesel engine, first cost is only one cri- terion of many on which to base your judgment: Of two similar engines as regards piston speed and power of, say, 600 H. P. offered, one may be priced at $80.00 per horsepower, and the other at $90.00—a total price difference of $6,000.00. The cheaper engine may have a fuel consumption of 48 gallons per hour—the more costly, 40 gallons; a difference which, at 5%c per gallon, represents $.44 clear saving hourly, so that 1,363 hours’ operation will wipe out the extra first cost, after which there is clear gain to the owner. NELSECO-M. A.N. Diesel Engines are built for ser- vice, and are cheapest in the long run. Do not be guided entirely by price, but consider service, long life and ac- cessibility. These three are the more important as they constitute real economy. Before you select your Diesel, let the Nelseco engi- neers give you some valuable data concerning fuel consumption, maintenance costs and continuity of service. Their experience is at your disposal.
