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. McCall Boat Rentals took delivery of Doreen McCall, its second 183-ft. model from Gulf Craft early in 1999. This will be followed by a third boat, Hull #424 to the same basic design, in November. Main engines for each of these boats are six KTA38 M2. McCall is also building two 165-ft.
