Where is the port into which I spray fogging oil to winterize engine?

Winterizing is fairly easy. You can put the lower unit in a mix of water and antifreeze and run it to get all the water out and replaced with antifreeze. Next you can either spray fogging oil in and add fuel stabilizer to your gas tank.

Here is a link to more info.

Make sure the anti freeze is good to at least your typical lowest temperature. Drain the fuel or add a fuel stabilizer and run the engine until it dies. Open drain on bottom of float bowl on small engines. Pull the spark plug and spray the cylinder with fogging oil. If it will be stored in a place that rodents or vermin can get to it. Place poison blocks around the area. Nothing worst than getting an engine back into service and having droppings and chewed wires to deal with.

The main concerns are:
1. Draining and/or running all the fuel out
2. Fogging the engine with protective oil (fogging oil is available)
3. Remove the prop. The splice could use some lube and the number 1 cause of oil leaks is fishing line wrapped around the prop shaft. You don't fish? others do.
4. Hang the motor vertical (normal running position) should drain all the water out.

NO ANTIFREEZE!!! simply hook up to the flush fitting and while running start spraying fogging oil thru intake . you want to "load" it up with that stuff and don't rev high for about 3 or 4 min the just disconnect battery and spray motor and pump down with WD-40

Drain lower end gear oil n look for sand in oil if only water just replace gear oil! Pull carburators out and clean and replace gaskets then pull all spark plugs out and spin engine at W.O.T.(wide open trotlte) also while turning engine spray oil (fog oil for winterize)to lube crank, rods,pistons and cylinders that way when first start is

The best way is take out the spark plugs and spray down the carburetor throats while the engine is turning over. The whole point of fogging oil is to fog the lower crankcase, crankshaft, bearings, and pistons and stop corrosion in the off season.

The fogging oil does not go in the carb. It goes in the cylinders. You have to remove the spark plugs and spray the fogging oil into the cylinders. Turn the motor over a few times with the plugs out , respray and then replace the plugs. You are protecting the cylinder walls by doing this. hope this helps you. Jeepfxr

add Stabil to the gas tank and run the engine for a few minutes so it gets into the carb. Then pull the plugs and spray fogging oil into each cylinder and then turn the engine over a few times. If you are in a cold climate you should drain the lower unit in case there is water in it and then refill it with new lower unit grease. reinstall the plugs and you will be ready for winter.

To winterize a Force outboard you should start the engine and remove the fuel line. Remove the air box and while the engine is running rev up the engine a bit and spray the fogging oil into the throat of each carberator when the engine is about to run out of fuel. keep spraying the fogging oil until you see thick smoke coming from the exhaust area. The exhaust comes out of the center of the prop. When you see the blue smoke then keep spraying and let off the throttle and choke the engine so it dies. Stabilize or get rid of your fuel in the fuel tank and you can let it sit like that for the winter. Leave the outboard in the down position so that any water will drain by gravity out of the prop. When you want to use it next spring just hook up fresh fuel, squeeze the fuel bulb and fire the engine up. It will smoke for a few seconds until that fogging oil burns out of there but it will be ready to run.

i put oil in mine and i do not even start it and in a day its low on oil and theres no oil leeks in the compartment.
