The motor puts out white smoke when I added Sea Foam to the gas and at first I get a gooy light brown oil like substance coming out of the exhaust ports by the propeller. I have a 35 HP old Johnson Motor with a long shaft. It scared the heck out of me the first time I saw this stuff as I thought my engine was runined. Once I blew up an engine in my Pontiac Firebird when the accellerator got stuck and I threw the gears into neutral to stop. But I forgot to turn the key off and the engine got so hot so fast that it cracked and oil got into the radiator's water. That's basically what the Sea Foam produced, It dissolved the carbon inside the engine and it comes out the exhaust as a oil water mixture that's colored light brown or tan. But that's a good thing for the Outboard Motor as it's getting rid of all the carbon inside the engine that built up over the last 30+ years.
Now my Johnson 35 HP engine purs like a kitten and will idle nicely. I can go about 1.5 mph or so when heading into a wind at idle speed, which is perfect for trolling for crappie.
I don't actually drain the carb bowl as that would be hard to do. There's going to be some gas left in the carb bowl even after you run the gas out of the engine. I just unplug the gas line at the engine and run the engine until it stops. Then I take out the spark plugs and spray Fogging Oil into each spark plug hole. That coats the top of the pistons and the cylinder walls with some oil to keep any moiture from rusting the metal inside the pistons etc. I'll turn the engine over a couple of times to spread the oil around inside the piston and cylinders.
I've done these two things for 30+ years now ever since I bought my boat brand new back in 1978.
Hope this helps others in some way.
