I am new to the outboard ownership world. I did a search and didn't find any info on this. <br /><br />After removing the cowling to inspect the engine, I see years of oil and junk on the outside of the engine. What is the best way to thoroughly clean it up? I have used engine degreasers on autos in the past and it seems to work pretty well. Can I use these products on the outboard? If so, what should be covered to protect it from water besides the distributor? Is there a drain that will allow water to exit that runs down toward the lower unit below the block? I suspect most of the water and grime will run down into the housing below the block.<br /><br />Thanks for your advice.
