4.3 efi year 2000 mercruiser.
Does anyone know the correct spark gap for this motor??
Any help would be greatly appreciated.

"The correct plug and gap shou

"The correct plug and gap should be on the label on your spark arrestor cover, along one side, likely the port side.
If not, it likely uses an AC 41-932 plug with a gap of 60 thou. This seems to be common to most small block EFI engines.
