I just picked upaa 2 stroke 1980-81 Mercury 7.5 horsepower. Any idea on what the oil to gas ratio is? Mercury wants $10.00 to answer the queston on their classic motors hotline and I don't want to pay for an answer.

    On the bigger motors it was 50 to 1, but for some reason I think the smaller ones like that were 100 to 1. I would double check me though. That was awhile ago that I had one of those.

    I've got an older 275 Evinrude V8.  50 to 1 for me.

    Like Chris mentioned, I believe it all depends on the size and make of the engine.
