After reading this thread, this was what I did Tuesday night.
First I hooked up all the hoses from draining the water out last Sunday. Then I ran 3 gal of anti-freeze through using a bucket and hose.
Third I pulled off the fuel filter, dumped some gas out and filled it with 2 stroke oil. Then I ran 2 more gal of anti-freeze through as the 2 stroke oil hopefully "fogged the engine".
Last I changed the oil and fired it one last time until the oil pressure registered.
In the past I had sprayed fog through the throttle body but I guess that is not the best thing to do.
Thanks for the help...:cool:

I've never fogged an engine in my boat before. It sits inside, what does it hurt not to fog it?

P.S. Granted most of the time it's already blown up from the season, LOL...

The fogging oil coats the internal surfaces of the engine ... valves, seats, combustion chambers, and rings. It helps prevent rust from moisture in the air and "sweating" that happen during temperature variations.

I have fogged my engines for years but never thru the fuel filter. I simply take of the air cleaner, rev the engine to about 2000 and spray the fogging oil into the throttle body until the engine starts bogging down, then I shut it off. I have never had any problems...at least none that I know of. Is this method adequate or am I doing harm to my engine??

There is concern of clogging up the sensors in the intake if you have EFI. Probably fine tho. Certainly fine with a carb.

When I fogged mine that way I could never get it to bog down, I ve even tried spraying 2 cans at the same time into the intake and it didn't bog. I too have been told that this messes up the O2 sensor. I think I might try the 2 cycle oil in the separator this weekend.

Mine didn't bog down with either method.
I think you mean the MAP sensor.
The 2 stroke oil in the filter was easier for me.

Mercruiser has a special way that they want all of the E.F.I. motors done. In a portable 6 gallon gas tank 64 oz of merc 2 stroke oil 12 oz of fuel conditioner concentrate and 12 oz of fogging oil mixed with 5 gallons of regular gas. Unplug fuel supply from the engine plug in 6 gallon tank and run engine @ 1200-1500 rps for 15 min. shut down and drain all water out of engine and block and all coolers. This will procetect all the fuel system componets(high pressure fuel pumps injectors and regulators) and the internal engine parts as well
