Ski, the NL has a hose and fitting on the bottom of the crankcase set up for an exchange type pump out and fill. I fitted a hose barb and reducer to the threaded end of the hose and use an extractor type vacuum pump to pull out the oil. The 5KW NL only holds 2 guarts and the fill cap is on the front top of the crankcase. Thanks I'll keep and eye out for emulsified oil, the Luggar engine is only 46 cu in. Bore 2.6" stroke 2.8" 3 cylinders 10 HP @ 1800 rpm, a mighty mite.
Second oil change and run till warm, the oil came out crystal clear.

The drain port on the pan is on the front, and not really on the bottom. A drain from there leaves a few ounces in, which may be water. That's why I recommend taking off the dipstick tube and sucking from there. Just one 10mm screw holds it in, super easy. Stick a 1/4" tube in an see if any water comes out when suctioned.

Then after some running, open oil fill cap and see if rockers have any milkiness there. If so, it is still wet inside and more action needs to be taken. Dampness will rust valve gear completely to crap if left in that condition.

Water in generators paid for the construction of my boat, so you want to handle this carefully!!

If you changed the oil a few times I would run with a good heavy load and any fresh water moisture will boil off.
