I'm starting a new thread to cover the Repower of my 1994 54' Donzi (by Rosciolli) Sportfish. Today I formally placed the order for CAT C18 ACERT 1150 hp engines and ZF665A gears. These will replace the existing Detriot 12v92TTA's. In addition to the engines and gears I am also replacing the generators, propulsion controls, oil change system and likely other items as well that make sense while we are torn apart. I'm still making final decisions on some items and will post once I have info. To swap engines we have to cut out the salon floor and aft salon bulkhead as there are no hatches. Today we started removal of Settee's, carpet, dining tables, cabinetry and joinery work. We have done our mock ups and laid out the access cuts. The boat is scheduled to be hauled and go into a building on 9/26. I'll document progress and post pictures as we go along.
