Re: winterizing mercury 4 stroke EFI
thinkpar,<br /><br /> I have a 2001 60hp mercury four stroke. I was told by the service technition that these motors should never be fogged. He said that, since the outboards did not warm up fast enough, the thick oil could prevent the valves from seating well enough initially, resulting in damage to the valves. He mixed me up a tank with gas, stabil, and two stroke oil to run through the motor before storing. I tried this one year than later called Mercury directly to find out for sure the correct procedure. They told me they would not stand behind doing anything other than as described in the service manual. The service manual says nothing about fogging, just putting a little engine oil in each cylinder through the spark plug hole and rotating the motor a few times by hand.<br /><br />RCS
