Does anyone have spec sheets for the DD 12V92TTA DDEC engine and specifically what hp ratings they were available in? I'm being asked to validate if my new CAT C-18 1150 hp are an increase or same hp as the old 12V92TTA's that came out. All the info that came with the boat (very limited) list the DD's as 1150 hp. But none of this info is anything official. However, over the past years and online searches I was never able to find a listing for this rating. The closest thing I could find was a 1,080 hp rating. Even when I had the DD's completely rebuilt the DD shop that did the work said they could not verify exactly what hp rating they were even with a serial # search. The boat is a 1994 Donzi Z-54 so I'm guessing engines are maybe 1993 built. I have the serial numbers but that never seemed to help. Donzi (Rosciolli) could not help either. All the info I could find on the 1080 hp model seemed to match mine and looked the same except the heat exchanger but I'm told that is not uncommon to have builders use something different to fit specific boat configurations. Appreciate any help.
