I have twins on my boat and I have a maintenance question. Do these EFI motors have O2 sensors. I want to decarbon them using Seafoam but I have heard Seafoam damages O2 sensors. Can anyone comment on this. Am I OK to use the Dunk method with Seafoam or should I use a product such as Ring Free or Techron? Thanks
