Engine Fogging for Long Term or Winter Storage (Outboard Boat) - Tips from Tom

I've been a marine mechanic for years..he done a great job! The only thing I would do different is ,I wouldn't have pulled the plugs and sprayed the cylinders.. especially when you spin the engine with the plugs out you didn't have the water running..I know it didn't start but, it doesn't take more than 30 sec to start heating up an impeller..
One more thing ..store your fuel tanks full of gas..then there's no chance of condensation ....other than that good job..

After applying the fogging oil, do you screw in the spark plugs as tight as usual or leave them a bit loose? I have read in some places they say to leave them kinda loose. Thanks
David Jessee
David Jessee - 3 years ago
Hello Everyone screw them back in tight..that way when you go back to start it there already tight..but as much fogger he sprayed in to the cylinders . The plugs are probably oil fouled anyways..going to have to clean the plugs upon starting back motor..

What about the water in the engine when temperature falls sub zero? This could crack the cylinder heads. Don´t you need to rinse the engine with coolant antifreeze instead of water to make sure that no water stays in the motor-block. I'm looking forward to your comment. best regards from Germany!
Mortons on the Move
Mortons on the Move - 3 years ago
It depend on the engine, A larger 4 stroke with an intercooler you may have to do that if there is no proper drain. For outboards they are designed to drain in the vertical position. There may be some left but should not be filled in any cavities, so no pressure when freezing. Also turning it over a few times without starting it will run the pump dry and you should be good to go. I have never used antifreeze and never had a problem, just remember to check the lower unit for water.

you forgot to coat the camshafts, now they will corrode i guess...
Mortons on the Move
Mortons on the Move - 3 years ago
The camshaft is in the crankcase and in the case of a 2 stroke the wax will coat it doing this procedure. In a 4 stroke they will be enclosed with oil.

Tayjuice
Tayjuice - 3 years ago
You should always leave as much gas as possible in the tank along with the stabilizer, since there will be no air left in the container that can turn in to water, just pure gas if filled to the top. :)
Mortons on the Move
Mortons on the Move - 3 years ago
What do you mean by dirty gas? It really depends on the problem but if its old and not running well then probably. Stabilizers can only do so much. Its best to only leave a little gas in the tank anyway.

so would,nt you still have water inside your engine cooling ports,non toxic anti-freeze fed through a hose to your water muffs and through out the engine should make it good to go for cold weather. fogging is just one step just saying
Mortons on the Move
Mortons on the Move - 4 years ago
By turning the engine over without running it (like in the video when we spray in the cylinders directly) this will run the pump dry and pump out any water. There may be a little moisture but if the engine is down they are designed to drain without any large amounts that could freeze and cause pressure buildup so it shoulden't be a problem. Just make sure to do that last step and turn the engine over a few times without fuel to get it out of the pump.

very anal retentive
a fast very effective way is to add an oil/trans/2stroke oil/ fluid to the last bit of fuel before it runs out and dies and thats it
my grandad has been doing that for his fresh water boat for over 40 years and its the same motor and it runs like new
why spend 30 - 45 mins at playing lube up my motor when a simple 5min oil trick in the fuel will do

does the water pee out even when the engine is not on?
Simon Hager
Simon Hager - 4 years ago
Jason S no. There was water coming out when the engine was not on because the hose was forcing water through the cooling system. In normal use, the engine draws the water. There was no water to draw so he was forcing some through.

If you can find it , use graphite grease or carbon grease- an just a small swipe, on the plug threads. Those greases are conductive and so wont hurt the plugs ground . Normal grease is not conductive. I also spray the outside of the engine in water dispersant spray , wipe down and then use a hand sprayed silicon wax ( one for car paint) on the outside of the engine. That keeps the engine looking new by keeping the bolts and fixtures from corroding. Also the engine leg goes onto a support stand once the boat is parked - a couple of milk crates or a small stack of lumbar pieces - it helps relieve the transom of the motor weight and means you can move the motor up and down if the tilt tube grease congeals in storage. That makes it easier to break the tilt system free when the boat comes out of storage.

Just like was said on previous comments, fogging isnt necessary unless its going to sleep for longer than a year or 2. As an experiment, i left the cylinder head off an old 40 horse johnson (for parts had a scored cylinder) all winter in thick salt air. no fogging oil coating. next spring: not a hint of rust anywhere on the pistons or cylinders, and that was with the head OFF. For my 225 johnson, i put a mix of fresh 89 gas, 40:1 royal purple synthetic , and stabil. ran it for 10 minutes and im done. i think that fogging oil is actually bad for plug fouling, carbon buildup and possible detonation.

not really neccesary on a 2stroke.
i mean it woudnt hurt for sure. but the 2stroke oil allready coats everything and does a real good job of keeping it coated since its designed to keep an optimal surface tension and strength when mixed, we had our mercury 50hp thunderbolt in the backyard for about 15-20 years. sometimes a couple years without use. that thing still had perfect compression on all cylinders, and ran like a champ !

a 4stroke on the other hand is way more vurnerable to corrosion at the cylinder walls and valves. since there is no oil in the fuel. it washes them clean of oil, and wont prevent corrosion like 2stroke. my mercruiser 165 had low compression after just a year of sitting in the yard. still ran fine, but i`m overhauling it anyway because of it.

Good point. I would still fog a newer 2 stroke like the one in the video. They run so lean these days (grater than 100:1) that I just don't think its enough Oil for long term. The waxy fog will stick a lot better too. Overall I think you are right tho.

I did fogging and change the gear oil yesterday, the boat is wrap up, ready for the winter, For lubricating the steering cable, I have to do it next year, Also,my wheel is off center already, I have to figure out how to fix it, and do it next year.
Thanks again
Mortons on the Move
Mortons on the Move - 4 years ago
Ya know I thought of another thing that I should have mentioned. Its a really good idea to lubricate your steering cable if your engine is connected to a steering wheel. There should be a grease zerk where the engine connects to the cable.
Mortons on the Move
Mortons on the Move - 4 years ago
As long as your have stabilizer in the gas and engine it doesn't really matter whether you leave it connected or not. I disconnect mine as I don't store the gas in the boat.


Nothing else really, just the lower unit like in the video. If there are any exposed metal parts (like throttle linkages) It is sometimes good to spray them with a light oil to prevent corrosion.
Eric C
Eric C - 4 years ago
Thank you for your reply, Tom
I haven't done this before, just want to make sure I did it right. Do you need to unplug the fuel?
When I fog the cylinder? Anything else that I should pay attention? (Mine is Yamaha 2 stroke, outboard engine)
Thanks again
Mortons on the Move
Mortons on the Move - 4 years ago
You need to remove the spark plugs so you can spray the fluid directly into the cylinders but yes, just turn the key. The engine is just a big air pump and with the spark plugs out it will just move the cylinders back and forth with no compression and coat the cylinder walls.
