As the size and cargo capacities of crew boats has increased so has the combined and individual horesepower of the engines. Compared with 1998, the 1999 Cummins Mid-South order book
for crew boat engines has shown a decrease in the numbers of six-cylinder KTA19 M4 engines that, with a 700 hp rating, has been the standard in the past. At the same time they have, to date, sold, for crew boat application, a total of 55 of the 12-cylinder KTA38 M2 engines with a Heavy Duty rating of 1350 hp at 1950 rpm. Included in these orders were engines for the following new builds
