Fogging a EFI

The service manual says to use a remote outboard type tank, mix stabilizer and 2 cycle oil and idle for 5 minutes. I 've been told fogging may damage map sensor. I like to spray with storage seal in addition to gas mix. Never had a problem.

I've heard of using both marvel Mystery Oil and 2 cycle oil. What I've read about people doing is mixing a cocktail with the Marvel or 2 cycle in the water sep filter with fuel. Run the engine till it smokes, shut down and then change the water sep filters.
Personally, I never fogged an engine for a normal winter layup and never had any issues.

drain most of the fuel out from the fuel water seperator filer . refill with marvel mystery oil and reinstall. start engine and run until smokeappears. your done.
fogging or introducing oil into the dry plenum on efi engines, will usually ruin the mat sensor, or manifold air temp sensor. the oil ends up shorting the sensor internal as it is a wire element sensor.
also may ruin map, but usually that would take time if it happens and will not usually show up in spring.
you can also hydra lock the engine during its dormancy due to oil sttling and seaping thru dry intake into cylyders.

In addition to above procedures (whichever you prefer) how about removing spark plugs and putting a shot of oil in each hole then rolling it over a few seconds?

Take a remote 6 gallon fuel tank put fresh gas in it 93 Octane preferably. Add 1 pint of a quality two stroke oil to the fuel, Optimax or Yamalube etc. Then add the appropriate amount of Stabil fuel treatment to the mix. Hook up this mixture after having given it a good shake and run it through at or around 1300-1500rpm for approximately 5 minutes.
Do not run the fuel system dry. Shut off motor and spray any exposed components with a good fooging oil. Disconnect battery ground terminal and isolate it. Put boat in garage.
