Filed Under (Boat/Trailer Maintenance) by Debbie on 05-10-2007

Our Macgregor 26 had a Johnson outboard engine. This was a wonderful little engine provided we used it correctly, see article about using an outboard. Right now it’s fall and time to think of winter and doing your engine lay up.

One of the biggest issues with winter lay up is protecting your engine from dirt, corrosion and rust. So I’m going to tell you what we used to do to ours, which was the procedure recommended in our “Official Shop Manual” for Evinrude/Johnson outboard engines. As always, if something doesn’t make sense, talk with your local marine mechanic.

Our fuel tanks were portable cans but if you have a built-in fuel tank, add a fuel conditioner per label instructions and top off the fuel tank. You’ll probably want to run the engine (with the boat in the water or a hose hook up) for 4-5 minutes to circulate the stabilized fuel, we do this on both boats we have now.

If you have portable six gallon fuel tanks:

  • Have five gallons of fuel in the tank.
  • Add two quarts of Storage Fogging Oil.
  • Add one pint of outboard lubricant.
  • Add one pint of 2+4 fuel conditioner.

Shake the tank to mix well then connect tank to engine.

Run the engine at about 1500 rpm for about five minutes. Remember, you have to have water so either hook up the hose, take the boat to the water on the trailer and run it or you can do what we did…buy a cheep garbage can, put it under the engine (so the engine fits down into it) and fill it with water. Just remember boat’s need water! (See that post here.)

Ok, now turn off the engine and take off the tank. Then you need to take off the engine cover and remove the spark plug(s), be extra careful as dirt around them can fall into the holes, which can cause engine damage $$$$. Spray a generous amount of storage fogging oil through the spark plug hole(s) into each cylinder. Be sure to turn the flywheel several times (clockwise) to move the oil through the cylinder.

Ok, remove the engine from the water, you know…pull out, disconnect the hose or dump the can and rotate the flywheel again several times to drain the water out of the water pump.

Clean and regap spark plug or replace with new. I like new because I’m a worrywart…. Leave them disconnected until spring.

The book said to safely dump the fuel if you’re not going to use it in other outboards; my hubby always used it to do all the lawn equipment…. Be sure to store them in well-ventilated areas away from open flames…duh, huh?

Drain and refill the gear case and check the gaskets, replace if they need it.

Lubricate motor (see check list).

Remove and check the prop. Also check the shaft seal for damage and debris, like fishing line. Clean and lube shaft with a triple-guard grease and put the prop back on. Use a new cotter pin or locking washer.

Now grab an all purpose marine cleaner and scrub up the outside of the engine. Then you can store in an upright position until spring, again in a dry and ventilated area.
