There are two kinds of PP. Mechanical which uses a servo motor for carbed boats. DBW or drive by wire is only for EFI boats. For a carbed boat you need a master module that doesn't say DBW and a servo motor. Other parts are the same (display, paddle wheel or gps, wiring harness). Good luck and PP people are very friendly call em up for a chat.
