I just changed the oil for winter lay-up in my Yanmar 3YM30 and noticed that there are two places on the engine to add oil. One is on top where I have added oil previously and there is another on the upper front starboard side of the engine. Both have identical colored caps and both say "oil". There is only one dipstick for the oil.
Any suggestions as to what the one on the starboard side (top) is for, and would it use the same oil as the rest of the engine?
I have a manual but I don't find any info on the two fill caps.
