Since it rotates clockwise, it may have a left hand thread, so that it doesn't come loose when the engine is running, but it would tend to tighten up instead.

Yeah a 18x8 is probably OK as is the 16x10 three blade. Maybe a 20x6 or 20x8 even. Hard to say for sure until you get it running. You might have to try different props on it. The gas two stroke engines tend to act more like four stroke engines in that they like larger props on them.
