I recently purshase a 2005 250 Mercury Efi 3 liter. I am putting this in the place of a 1995 Pro Max 225 EFI 2.5 liter that I will be selling. As I have changed the motor over I could not find an appropriate location to conect my water pressure guage. I also could not find a location for my Dash mount thermostat guage sending unit. I have looked through the manual and no info was found. If anyone has any suggestions or information i would appreciate it.
