Fogging a 5.0 efi

[Jeff Delbuono]

Silly question but not really sure of it. I have always had carbed motors on boats and now have a twin 5.0 efi. When winterizing do i fog the motor or will this screw up the fuel injectors.

It won't screw up your injectors one bit by spraying fogging oil into the TB since the injectors sit up on top (because you have an EFI, not an MPI). However, the fogging oil could mess with sensors. Instead, fog the engine through the F/W separator with 2cycle and stabilizer.
