"Fogging" new VP 4.3?

[DBIdaho]

My owners manual says to mix two stoke engine oil into my boat's fuel and run it through to get the necessary corrosion protection over winter lay up.
With my previous Merc carbed 4.3 I simply sprayed fogging oil into the carb.
My VP 4.3 is high tech with high pressure direct injection, O2 sensors etc. Is there a reason I shouldn't simply spray fogging oil into the intake/throttle body? This is a non-CAT engine.
If I can't fog the engine, what is the recommended premix ratio of the two stroke oil?
(if i premix things will be smokey for some time next spring. ....got a fair amount of fuel in the tank)

the two cycle mixture is 50:1. the process is to mix it up in an outboard motor tank, then disconnect your fuel line between the gas tank the fuel filter. hook that line up to the outboard motor gas tank. have enough fuel two cycle mixture to run for 15 minutes as you do not want to run the system dry. you run the boat for 5 minutes on the mixture at 1500 rpms.

All done.

Here is link to the service bulletin on the process.

Thanks,
I downloaded the free VP maintenance manual which had the process that you describe.
But I downloaded it after I had the engine winterized with pink antifreeze in the seawater side, so I didn't want to do this again.
I did mix a gallon of >30:1 in the remaining gas in the fuel tank. The mixture was likely <50:1 but I ran it for at least 20 minutes and got smoke from the exhaust. So I'll sleep OK this winter, and be prepared to perform the process by the book next winter.
