How to fog 8HP Johnson outboard and run out gas?

[jimwalt]

I think I want to totally clear out all of the gas on my 8HP Johnson outboard before winter storage (this weekend). How can I fog the engine and get all the gas out at the same time? I've disconnected the fuel line in past and it will continue to run for 2 to 3 minutes

Also should I fog while in the lake, or in a bucket of water at home? This is my first year with a motor.

I do plan to change the oil in the lower unit first, before fogging.

Thank you.

in a bucket, fire up the motor, pull the fuel line, and run for a few minutes on the fuel in the carb, then fog

 

[jimwalt]

How much fog? Entire can??? Spray in carb right? Thank you.

Make sure water pump is submerged.---Remove airbox cover.------Start motor.-----Disconnect fuel line.------Let motor run , start spraying short bursts of oil into carburetor just before it runs out of fuel.----One can should do you for 10 years on an 8 hp !!!

Leave the fuel line connected, fog it while its running in a bucket, when it stalls pull the drain plug out of the carb to remove all the gas.

Disconnecting the fuel line and running until it stops doesn't drain the carb, it only lowers the fuel level.

Many carburetors do not have a drain plug.----Running the motor and pulling the choke as it starts to die gets 98.5% of the fuel out !!

I agree.

...back to the little hex bolt covering the h.s. jet. Remove the bolt/plug and drain the carb (Don't forget to replace it, or you will never find it in the Spring!)

Well, well, well------Does the 8 hp model have that drain plug on the carburetor bowl , yes or no folks ?----Jim would like correct and factual information to winterize an 8 hp model.

If it's in fact Jim's '77 6hp, it would be a good opportunity to make sure the jet is clear as well, after draining the carb.

I have a 6 HP 1977. I cleaned the jet a couple days ago and it runs like a dream now.

I talked to they guy I know that owns the motor service business and he said that I would best be served by doubling the amount of marine stabil in the gas tank, running it a bit to make sure it gets in the motor, then doing some short bursts of the fogger until it stalls. He suggested leaving the fuel in the motor. He said it would be fine. After that he suggested changing the oil in the lower part of the motor.

I'm going to store the motor in my basement over the winter where it will be safe and warm until next year.

Just disconnect the fuel line while it is running. When the motor starts to rev up start spraying fogging oil into the motor until it dies. Pull the choke as it starts to die and you are done.

 

[oldboat1]

same motor discussed and pictured in your earlier post, I'm guessing.

There is mixed opinion on storage. I'm on the side of emptying the carb as best you can before storing. If storing some gas in the tank, stabil is a good idea. In any case, basement storage is much better than many motors get. Store it upright -- might want to make a stand, if you haven't done that.

No 8 hp marketed in 77----I give up.

I'm an idiot. It's a 6 HP..... I often wish it was larger (faster) so I dream the number is larger. Sorry.

If your first year with the motor, not a bad idea to change out the l.u. oil as your motor guy suggested. I would get a pump to do this, as it can be messy -- something you might not want to do in the basement. Go to the service guy and buy some l.u. oil and a pump to fit.

I have three of those motors, I shut it off at the end of the season. At the Start of the next season I pull the rope and resume boating.

In other words, there is no winterization done. And never has been since the first one was new in the late 60s

And where do you live? I live in Michigan.
I'm glad that works for you, but i'm going to take the time to winterize mine. Its a cheap insurance policy in my opinion.

 

[ondarvr]

I didn't say there was anything wrong with winterizing, I just said don't, and have no problems.

Hi Jim,
As you can see, when it comes to storing outboards, snowmobiles, motorcycles, ATV's, etc. you're going to get a variety of methods and opinions on the "right" way to
do it. All you can do is pick the one you want to go with, and most likely you'll never have a problem. For me, I used to do as has been suggested by running my outboard at a slightly higher than low idle and spraying bursts of fogging oil thru the carb intake until the engine ran the fuel out of the carb. Always worked great.

In the last several years I make it even easier on myself. I just run the motor at a slightly high idle until the fuel runs out of the carb and it stalls. I then pull the spark plugs and spray liberal amounts of fogging oil in both cylinders, turn the motor over by hand a few times, and spray a bit more fogging oil in the cylinders. I then clean and check the gap on the plugs, or replace them if they've been in there a while, put them back in, drain the lower unit, and put it to bed. In the spring I put new oil in the lower unit, grease the grease zerks, and I'm good to go. I discovered that on every two-stroke engine I have ever torn down internally, even after it had been run dry of gas, that the bearings were always still very oily. I have since not worried about getting the fogging oil into the bearings, and find it more convenient to spray directly into the cylinders and do the aforementioned spark plug service at the same time. And now for the magical final words: "I've never had a problem when doing it this way."
