use TC-W3 2-cycle oil (I like pennzoil). 16:1 ratio if you like to see a rainbow on the water behind the boat. I use as little as 32:1 ratio gas to oil with a good name brand 2-cycle oil with no ill effects.
Only crank it in water to spare the water pump and if it doesn't send a little pee stream out the tube at the back bottom of the cylinder, your pump impeller is bad.
Gear case in foot uses grease not oil. use Lubriplate 105 grease available at Napa.
