Author Topic:   Engine Fogging

Kolbert posted 10-24-2002 11:26 AM ET (US)
Just went to fog my engine (90hp vro Johnson) for winter storage, followed the directions but the engine didn't act like they said it would.
I took off the carb cover to expose the air inlet, started the engine, and then sprayed the fogging oil into each of the 4 inlets. The engine would sputter slightly and white oil smoke would come out the thru hub, but the engine didn't die like they said it would. Is this proper? What am I doing wrong? Should I leave the carb cover on and spray the oil into the main air inlets so it can be sucked in by all 4 inlets at once?
Any suggestions?
Thanks,
Austin

Austin,
That sounds perfectly normal. Those Johnson outboards are incredibly robust and can run on just about anything. All you can do is deliver more fogging oil at a faster rate.
To that end you can get from your dealer a small fitting that will replace the acorn nut on the red lever that you throw to manually prime the engine. This will allow you to insert the nozzle of the can of fogging oil directly behind the air intake and get that fogging oil directly into the carburetors. It's much cleaner and easier and can be used with a can of Engine Tuner or equivalent.

Austin -
When I used to fog my old 1982 Evinrude 90, it sometimes wouldn't stall, it would rumble & cough, but not die (maybe some years it stalled). I would move the fogging can "straw" from one carb to the next, giving each a good blast, and I'd do this several times until the neighborhood had a pall of white smoke covering it. My 6 Yamaha ALWAYS stalls when I fog it. Maybe your 90 was not warmed up enough, I never fogged a cold engine. Maybe the 90 is strong enough to keep running through all the rumbles. The white smoke tells you the fogging oil is making it through they system - that's good. If you have a fuel stabilizer in your fuel, you should be all set. Pull the plugs, check the spark plug gap, spray some fogging oil into the cylinders, turn the engine over to move the pistons and spread the fogging oil in the cylinders, spray some fogging oil on the plugs, replace the plugs, do the rest of your winterization. Have a happy holiday season. Start her up in the spring, go boating.
My 225 does the same thing, I can't stall it.
There are more experts in the Forum who might have some more advice, but I think you're OK.

With winterization upon us, I offer this one reminder:
When fogging your engine with an aerosol spray can and a tube stuck in the nozzle, be sure you have firmly seated the tube.
If the force of the spray ejects the tube and jets it into the engine intake, you can create plenty of problems for yourself.

Get the fogging fluid with the hose that connects to the tire valve thingy where the red lever is to prime the engine. this injects it right into the engine. Trust me....she will stall.

Thanks for all the feedback guys. Bigshot shed some light on one of my questions, at least I know what that cap and valve are for now.
Looks like I did the winterization at just the right time. In southern New Hampshire yesterday, we had our first snow of the season. Some of it even stuck around overnight. Here's hoping for an early spring. I am finishing up my console project on my Sakonet and can't wait to install everything. Pictures to follow shortly thereafter.

Hey Bigshot -
Have you ever fogged your 70 Evinzuki? The Evinrude manual doesn't mention it and doing it the way the Suzuki manual describes it I can't get enough oil up the intake to do much good...Bob M.

I just winterized my 1996 Johnson 90 HP and could not get it to stall either. Sputtered and coughed, but it did not stall. Made a ton of smoke.

Listen to BIGSHOT.
I've been there and done it.
