In the oil or UNDER the pan. They can rust out from outside-in too.

Consider the possibility that the oil pan has a pinhole rusted in it.  A small 
amount of salt water in the oil is all you need.

I moved my boat to its winter home yesterday and then tried to change to oil 
after I arrived. I had no issues along the way- engine stayed cool and ran 
smoothly.  However, I got almost no oil out of the pan and the dipstick showed 
it was below the low point.  I am thankful that this did not destroy my engine 
but now have to figure out what to do.  I noticed some oil in the bilge in the 
spring so cleaned up and put 2 oil absorbing sheets in the space under the 
engine and one in the bilge.  My boat came from the PO with a hose attached to 
the oil pan drain plug so I could remove the cap from the hose and run a thin 
tube into the hose to suck the oil out. I thought that I had not tightened the 
drain plug under the oil pan when I changed the oil last year and thought that 
was the cause of the leak.   The pads under the engine now have oil in them and 
I added a quart of oil to the engine a month ago when I checked and it was low. 
 It is still possible that the drain is the source of the leak, but the leak is 
slow enough that I am having trouble verifying the actual site.  Has anyone had 
this problem with a Universal M4-30 or similar engine?  Of course I am 
concerned that I might be burning the oil, but the pads underneath with oil in 
them leads me to think it is a leak.  Still, I am not sure I can account for 
several missing quarts of oil in the pads.  Dave
