Re: Sea king 6hp
1966 made by Chrysler. So you can feel free to post future questions up in the Chrysler/Force heading to maybe get a little more input. Although most who read those read these too. Just make sure you mention Sea King by Chrysler.
Original ratio was 1 qt to 6 gal using SAE-30 motor oil (24:1). You might be able to cut that amount of oil in half using any 2-stroke outboard oil, but I'd probably shoot for 4oz per gallon for the moment. I don't have a parts breakdown at hand, but if your main crankshaft bearings, rod crank and wrist pin bearings are all needle bearings, you can go to 50:1 (1 pint to 6 gallons).
