All the new Evinrude ETECs are winterized using outboard oil. It is done automatically, you do a little song and dance with the key and the fast idle lever, then it takes over, rev's the motor up a little (cannot tell how much, it actually turns the tach off!) then heavily oils the engine using the built in oil injection system. Then it turns itself off, with no input from the operator. Winterizing done, take about 30 seconds per motor.

now, when you consider that the Show team has 5 boats, twin rigs and triple rigs (yes, my boat has 3 150 hp motors on it to pull the 30 person final pyramid... this saves a lot of time and money!

www.5sst.com for a picture of the big pyramid. Those digging longer would find pictures of the triple rig.

If I had to pick 2 out of 3 to winterise my boat it would be 1] fogging oil, 2] two cycle oil. Both have been designed to lubricate and and protect internal parts. And in a 2 cycle motor, the oil mixture is all it has. MMO was made to 1] clean and 2] mildly lubricate.If your using good quality oil and change it when it needs, I don't see the point of putting it in the oil. And when you put in the gas, it burns off so cleanly I can't provide much lubrication or it would foul your plugs.If keeping a coating of oil on the valves and cylinders during long term storage is what your trying to do, You got to use the right stuff. I've seen motors laid up for over ten years start and run smoothly even tho they were stored outside after being properly winterized.You have to know the oil you use will do it's job, not hope it will.,,

I just slowly pour a bottle of any 30w down the carbs in my 454 Crusaders until the engine coughs, then flood it out with a quick pour. Works fine and it's cheap and easy. Engines start just fine in the spring.And no, I haven't torn down the engines to see how they really are. I also think it's helpful to plug the exhausts and carbs to prevent moist air flow through the engine, which can condense and form rust.

MMO makes a good fogging oil, we've used it as a fogging oil for many, many years. My brother fogged a Chevy 350 engine with it and took the engine out of storage over 20 years later to sell to a friend to put into a pick up truck. He pulled the heads and replaced the cam for his friend before he put the engine in the truck. We were all a bit concerned about the condition of an engine left in a damp garage for that long. (The cam was too agressive for the automatic tranny his friends P/U had in it). The insides of that engine were in perfect condition, and after over 20 years it ran well once installed in the PU.

I would not use an engine oil as a fogging oil, the additives could cause problems when poured into a running engine to fog it. TCW-3, MMO, or fogging oil are better much better choices.

Another way to easily fog an inboard engine with a fuel water seperator filter is to pour several oz of 2 cycle oil in the new fuel filter and then run the engine a minute or two. It will coat the entire system. You will se the smoke as evidence.

Well, I actually had some fogging spray, Mercruiser brand, left over so I used that. That stuff was more like foam spray than oil. Yes, it was thicker and I was wrong about that.

Motor oil is fine, I have used it for years before you could buy fogging oil. Recommended by Merc and OMC in their manuals..

There are better choices now, and that was the point I was trying to bring out.

I read a Mercruiser owner's manual for a newer boat, it said the other choice than Merc's fogging oil is 20W engine oil.

Bluestream, the ideal storage/fogging oil is one that is:

1) Easily distributed
2) Leaves a coating on metal surfaces to protect them from corrosion
3) Will burn off cleanly when the engine is started.

MMO is just about ideal for this application ... followed by a TCW-3 2-stroke oil (low/no metallic additives).

Engine oils are specifically formulated not to burn off easily and they have some metallic additives (moly, zinc, phosphorous, etc ....) which could foul-up emissions equipment, sensors, spark plugs, etc ...

Sounds like you have been getting away with it to date OK ... but as others have said, there are better products for this application ... and they don't cost much more.

With butane, propane and naptha, I just don't see how that would protect an engine during storage.


Butane and propane are for the propellants in the can. Naptha is for creeping and penetrating.
