The 10 is a great little motor We had a 56 when I was a kid.I drove the h--- out of it for 3 or 4 years and it never missed a beat.I was only about 100 lbs then and it would scoot along about 21 mph on our 14 ft Crestliner.
It is very unlikely gear oil got into a cylinder
unless stored upside down and even then it would be a trick.Normal exhaust residue can be black and oily.Slop in the gears is normal as the clutch dog and gears ingage with two dogs.
Get yourself a manual and go to it.Check the gear lube if it appears milky you should change the seals and inspect the prop shaft for wear or play.Some folks run with leaky seals if not too bad and change lube more often.Fuel mix is 24:1.
Use TCW3 rated oil and don`t cheat.Routine parts are available at NAPA auto parts and of course well established Evinrude/Johnson dealers among others.You`ll find it can be difficult to shift when not running this is normal and rotating the flywheel will aid shifting.NAPA also has aftermarket service manuals among other suppliers.Unfortunately some NAPA branches don`1t have a clue about their 600+ page marine products catalog.
