What does mean avaible? I short now in my 3d Di someone installed MPEM from RX di .Engine start / work ok but there is a problem wth guages ,like U now 3D have difftrent Guages than all sea doo models ( also fuel level sensor too - i check that too) An other Little difftrent is that SeaDoo 3D di dont have EGT sensor, rest Di models have ,I can and it but the Best option is change MPEM exactly from 3D di .
