Re: fogging

There are different methods, depends on the EFI. What is your engine serial number.

DonS, I'll jump in here. I have a 2007 Merc 5.0 MPI (SN:1A068210). I was actually wondering the same thing and found this thread through a search. Any input would be great. I looked through the manual and may have overlooked it, but I don't remember seeing anything on this.

Re: fogging

Well, I searched through the manual again and found this:
1. In a 6 gallon remote tank mix the following
a. 5 gallons 87 octane
b. 2 gallons 2 cycle outboard gas
c. 5 ounces fuel stabilizer
2. Allow engine to cool
3. Active the Schrader valve to relieve fuel system pressure
4. Close the fuel shut-off valve
5. Connect the remote tank (with the mixture) to the fuel system
6. Start the engine and operate at 1500 RPM for 5 minutes

Should (1.b) actually be "2 quarts 2 cycle outboard oil"? 7 gallons probably won't fit in a 6 gallon tank. ;)

There's something wrong with the math here. 5+2+1/3 stabilizer= 1 &1/3 gallons more than a 6 gallon container can hold.

Re: fogging

Um, hmm, typo; should be 2 quarts of 2 cycle outboard gas. Sorry about that.
