How to fog a Mercury four stroke

[M_Miller]

Does anybody know how to fog a Merc 4 stroke? I can't seem to find the air intake. I have been pulling the plugs and squirting in the fog oil with mixed results...

Thanks,

MM

I have been doing like you. I would like to know if there is another way as well.

Thanks for posting.

Never heard of fogging a 4 stroke.

Some manufacturers don't even recommend fogging the cylinders like you are doing. (my last Honda)

 

Read the owners manual and if you don't have one get it online.

Complete winterizing instructions will be found there.

The reason for oiling cylinders is to keep cast iron rings from freezing in the ring grooves due to condensation induced rust. The best access to these is through the plug holes. On a four stroke if you rotate the engine 90 degrees,fog the cylinder,and do this 8 times you will also coat all the valves and seats. It may not be necessary but it won't hurt anything and may save engine damage.
