duced load, lower oil temperature, lower engine tempera- ture and thus reduced stress on components ? and by that increased durability and longer life. It also means longer service intervals for the whole package, for the IPS unit as well as the engine itself. A FULL SUITE OF CLEAN & EFFICIENT ENGINESIn a North American workboat market where the collec- tive ? eet is getting progressively older, more ? and better choices for operators is always a good thing. Thats because ? as we note in this editions BY THE NUMBERS report, the percent of the American ? eet (alone) which is older than 25 years old has more than doubled during the past twenty years; from 18 to 40 percent. In the workboat mar- ket served by the engines described above, the rebuilding of replacement tonnage in all categories, and in some cases, retro? tting existing tonnage to meet more stringent envi- ronmental requirements, will continue for the foreseeable future. It simply has to. Think about it: as many as 15,405 hulls in the domestic brown water trades are now older than 25 years. Certainly, some have enjoyed the bene? t of a re-power refurbish- ment. Most, however, have not. Fortunately, the choices are to get the job done are many; they are fully compliant and they represent the vast array of the worlds best engine OEMs.
