Winterizing Johnson 9.9hp (Fogging oil in Cylinder)

[Chrisravosa36]

Hello, this is my first time winterizing my motor, I like in Massachusetts, so it very necessary! My buddy told me I should spray the cyliders untill they are about 1/2 full and then pull the cord, so I did that, he does work on small motors, he said this works with his well, but it didnt for me...I did this, pulled it many times before putting the plugs back in, confident I got most of it out, I put the plugs back in and tried to pull her. It was tigh. the cylinders seemed to have been very very tight and pull starting was near impossible. I tried a few pull starts, didnt work (kill switch off along w/ lower unit) nothing. I though it could be hydrolocked, but both of the pistons are going up the full way, plus I didn't start it.I suspect it is too much oil, because il screw the plugs in about 1/3 of the way, and I can hear the oil bubbling and just liquid noises in general. So should I just let it air out over the winter? Did I screw up my motor? Should I put it in a room with a dehuidifier?

Anything will help!

Thanks!

I doubt if you caused any irreversible damage; if stored in a dry place, I would lay the engine horizontally with the spark plug holes facing down for a few days and the spark plugs removed. Try turning the flywheel at least one revolution each day. I would think after a few days all should be ok.

It makes no difference at this point, just leave it until spring, no damage has been done, it's perfecly normal to not be able to turn the motor over after filling it with oil like that.

For future reference, fogging oil is normally sprayed into the carb until the engine stalls. That's it. Drain and replace l.u. oil. Can wrap the l.u. with a plastic bag to keep critters out.

You need a new buddy . . .

Is this a 2-cycle engine? If so . . . My take is that too much oil is now in the crank case and is causing the hydrolock, Best to lay it on its side and see if if you can work the the excess oil out of the engine.

Not sure what a dehumidifier will do since we are taking oil not water (right?)

Well it removes all kind of mousture in the air, in not sure id want to do that, because it could leave crap behind and evaporate the liquid?

Also, Im most likely going to leave it in my basement, its always 50 Degrees or more down there, should I take the plugs out and leave the cowl on? or should I leave the plugs in?


I can easily pull it when the plugs are out, but when I put them in, its hard put possible.

I am in MA as well, 26 degrees F thus morning. I just leave my outboards in the garage, but it usually stays around 35-40 F there. I am assuming you have a 2-cycle engine :noidea: Or is it a 4-stroke?

The key thing would be to get the excess oil to drain. So I would position the engine in a manner where the intake or exhaust ports were facing down and oil could drain out of the spark plug holes. I would have the plugs out so it can drain.

For the future, you may not really need fogging oil on a 2-cycle, since the fuel has oil in it and goes through the internal parts of the engine. The prescribed method for fogging my Mercruiser MPI engine is with 2-cycle oil mixed at high concentration with the fuel.

I have a 35 horse Johnson 2 stroke, a 9.5 Johnson and a 5.5 Evinrude. I personally do not fog any of those. They are all stored indoors (Garage, shed, shed) so they are exposed to the cold buy not the other elements.

What I do is pull the ropes at some point during the winter just to move the position of the pistons. I'm sure this does absolutely nothing for them but it makes me feel good.

Fogging is a good practice and if you go that rout in the future I would suggest using old spark plugs and changing them in the spring after you have run the engine and burned off the oil.

Sorry I forgot to respond to your question earlier, its a 9.9hp 1987 or 88 2 stroke. The lower unit screws are not budgin either, I used some penatrating oil, nothing, I used a decently big flathead, but tonight I may try picking up another bigger one to get her open, dont want to strip the screw!!!

My oil does leak a bit out a side hole on the motor, im not sure what seal this is, but il take pics tonight!

 

[racerone]

Oil leaking out those small holes on your motor may well be normal.------Penetrating oil on lower unit drain screws does not help as the seal prevents it from reaching the threads.

 

[Chrisravosa36]

Oil leaking out those small holes on your motor may well be normal.

So I dont need to replace any seals?


BTW.Thanks so much for all your input, I was worried sick that I killed the motor!

 

[racerone]

The lower unit can be pressure tested to find / identify any leaking seals.-Ask your buddy to explain the winterizing process again.---You may have misunderstood him.

 

[ondarvr]

After filing the motor with oil like you did, you may have oil leaking out in many locations, at this point it means nothing. To get the screws out of the lower unit you may need an impact screw driver, but try the very large screw driver first, just look to see if there's water in the oil you drain out, then refill.

You don't need to bother draining out the oil you poured into the cylinders, it can be left as is until spring, it's not going to hurt anything.

I will add my 2 cents to the issue. I don't worry too much about fogging the motor unless I thought it was sit up unused for more then one season. The issue with fogging a 2 stroke is that you want that oil, not only in the combustion chamber but also in the crankcase. The only way to get it in the crank case is to run the motor and hopefully stall it as you are spraying in the oil through the carb. I also like to run my motor out of gas at the end of each season. I know it doesn't get rid of all the gas, but getting rid of the most gas is one of my objectives. Unfortuneately I have not figured out how to spray fogging oil into the carb while it is running and run it out of gas at the same time.

So what I do, since it is only going to wait over the winter to be used again, is to run the motor with a little higher concentration of 2 stroke oil, on the last run of the season. So I use 4% to 5% oil in my 2% oil to gas recommended motors and then disconnect the fuel line at the tank and let it run until it dies. At the moment of stumble I pull out the choke and hopefully that gets rid of as much gas as I can and gets a little more oil into the crankcase. As I said, this hopefully gets as much gas out of my gas tank line, my motors fuel lines and the carb. Since I always check my spark plug at the end of the season, I spray a little fogging oil the holes (I said a little, I don't 1/2 fill the chambers. That is not needed) with the motor tilted up and I move the flywheel by hand clockwise to spread it around in there, as best as possible.

The easy method is just fog it, don't bother running dry, because as you said, it doesn't remove all the gas. Then just loosen the drain plug on the carb and let it drain out completely, that's what it's there for.

Pouring

 

[ondarvr]

Hit the wrong button.

Pouring oil into the cylinders like the OP did will put oil in the crankcase, it will flow through the transfer ports and around the pistons and reach the crank.

 

[racerone]

Well , if you run the motor you disconnect the fuel line and look at your watch to see how long it takes to run out of fuel.----Then you start it up again and disconnect the fuel line.----Start spraying the fogging oil in 10 seconds before it is likely to run out of fuel----You are then done !

Unfortuneately, not all carbs have a drain plug, so running it out of fuel is the only option if one does not want to dissemble it every year...and I don't. I should have added that I do put in fuel stabilizer as well, but I like to get rid of as much fuel as possible. In Canada, where I am, the off season is much longer then the on season, unfortuneately.

 

[ondarvr]

I would say about every carb I've worked has had a drain plug, now I'm sure there are ones without a drain, but they wouldn't be common on an OB.
