The Tug “‘N. Y. Central No. The Tug ‘‘Grace’’ 34” When You Dieselize, Consider That— HE many successful installations of Ingersoll- Rand Oil Engines in the marine field bear witness to an engine that meets all the require- ments of a varied and exacting service. Due to conservative rating and an ability to handle overload, these engines guarantee the high reserve power so necessary to marine work. They show such high fuel economy, in com- parison with steam operation, that it is usually possible to wipe out the initial cost in a few years. You can insure continuous service at low cost by installing Ingersoll-Rand Oil Engines in your next boat.
