Merc 1075&1200
 

I thought I read somewhere or I just dreamt it that 1075&1200 were the same motors just that the ecu was remapped to change it from 1075 to 1200hp. Can anyone shed some light on this subject? Thanks

I don't think that is true. The 1200 had an alternate ECU to run non-race fuel, and I think the HP fell to something like 1025 on pump gas. Betting most parts are interchangeable though, with differences in cam.
