I believe that would be the West Bend / Chrysler motor, one of the very few air cooled outboards that I show any appreciation for. I actually think they are pretty good, for what they are. It has the old West Bend powerhead that is related to the old Kart engine, but less power and plain bearings, etc. Back when I was racing karts, those durn West Bend kart engines would smoke me and my souped-up Clinton with dual carburetors.
Anyhoo, I would suggest 16:1 and probably chainsaw oil, because they run hotter than water cooled outboards. I don’t understand why they say not to use hypoid oil, when a Sea King version says to use "Wards Sea King Hypoid Outboard Gear Oil" It has stainless steel shafts, and "real" seals, so should be ok. One thing I like is it uses prop thrust to force water up a ram tube to cool the exhaust housing, unlike Eskas and their chintzy water pump.
