    optimax winterization cylinder fogging
from Fshrmn1010 (

 What is the advised way to prepare cylinders for winter storage? Have heard that fogging oil should not be used due to injeactor damage. Are you just supposed to add premium plus oil into the cylinders and rotate crank a few times?
Allready have ran Stabil in the fuel and ran it down in the tank. Thanks FSHRMN1010

   What I do... from bill spence (  12/8/2006 11:45:00 AM
 Remove plugs.

Spray about two seconds worth of fogger in each cylinder.

Turn motor over with kill switch off.

Spray fogger again in each cylinder.

Replace old plugs.

 The manual calls for 1 oz. Opti oil in each cyl. but try to to get in in those plug holes. The fogger is much easier. Just remember to go heavy on the fuel stabilizer, running thoroughly through the system and not so heavy on the cly. lube.

   Not recommended from BrianC (  12/8/2006 6:19:00 PM
 Fogging oil is not recommended when winterizing the Optimax - at least the newer ones. Not sure about the earlier models. From what I have been told, there is a known issue with fogging oil clogging injectors and potentially damaging the motor on down the road. Instead I believe the original post is correct that you just shoot some premium plus right in and rotate by hand. I believe you also use a mix of fuel stabilizer and Quickleen and run through the fuel system.

I am not an outboard mechanic but I have resarched mine pretty diligently and that is what I have found. I know my dealer did not fog mine and I discussed it with the mechanic, who agreed.

Hope that helps

 On my older opti I move the shifter in and out of gear like 4 or 5 times and it bleads the oil system which dumps extra oil in each cyl. so that fogging does not need to be done.

 I don't see how injectors can get clogged by spraying fogging oil into the spark plug hole.? Is that really possible?

   I have been told... from BrianC (  12/9/2006 3:52:00 PM
 that something during the startup process may allow it to happen. I'm sure there is someone on this board who could explain the issue in detail. As I said, I am certainly not an outboard mechanic but have seen this mentioned too many times and feel confident there is a legitimate issue. Even if that issue is overblown, one thing I do know for sure is that my owners manual says nothing about fogging oil. Considering the what the outboard cost, I personally won't be deviating from the manufacturers recommendations.

   sounds impossibel to me... from PumaJeff  12/10/2006 12:29:00 PM
 how can the fogging oil clog the injectors, when it does not run through them at all, if sprayed right into the cylinder????? Bill instructions/method is the best way for sure! :o)

   bassboatcentral from bassman863 (  12/11/2006 12:39:00 AM
 this site will tell you not to fog an opti they suggest 2to 3oz of opti oil per cylinder run quikkleen and stabilizer thru motor 20 to 30 min but don,t take my word for it check it out on this site.

   In the 2004 Optimax manual from Greg (  12/11/2006 8:16:00 AM
  It says nothing about fogging cylinders. The manual simply calls for DFI oil to be put into the cylinders via spark plug holes.

   Let me set this straight from Mike I.  12/11/2006 3:56:00 PM
 Fogging occurs when oil is introduced in to the air intake which in turn mixes with the fuel and then, depending on your motor(Carb, EFI or DFI)into the combustion chamber via a fuel rail. You are not fogging a motor by spraying oil into the plug hole. Fogging oil is a light oil with a propellant. All you are doing is lubricating the piston and cylinder walls to prevent corrosion. If this can somehow cause injector damage I would like to hear about it from an expert. I think that the fact that lots of us use "fogging oil" causes some misunderstanding as to what we are doing.

   Seems a little odd... from BrianC (  12/11/2006 10:06:00 PM
 that the "best way" would not be the way the manufacturer recommends, but I do see Mike's point that spraying fogging oil directly into the cylinder isn't the same thing as truly "fogging" in the conventional fashion, and therefore might not cause the same problems. Of course that assumes the fogging process is the root cause of the problem and not the fogging oil itself. Guess someone from Merc could say for sure.

I personally still feel more comfortable following the owners manual.
