Any idea what the gph consumption of a 70 hp 2 stroke might be?

Unless I'm missing something, I'm not overly concerned about pairing a
2 and 4 stroke main and kicker, provided that the 2 stroke is oil
injected from a reservoir under the cowling. I can use one fuel
source, right?

Is the fuel consumption of a 2 stroke roughly comparable to a 4
stroke? I know there are differences between carburetion and efi--
just looking for a generalization. I prefer a light engine on this
light boat.

Thanks,

John
