A friend had that problem. Turns out he was turning the motor over with the starter several times while in winter storage. As described above, the gas evaporated and the oil was left.
They make a slide-hammer with a vise-grip attachment. I got mine off of amazon.I had the same problem with a ‘68 18 Evinrude. Clamp it above where the water pump housing goes.
I have a mid 70’s omc outboard with no spark . Don’t know the brand because it’s been painted. Model # 50RL78S. Coils checked good with a Merc o tronic. There’s no continuity from the two leads coming from the stator. Any help will be greatly appreciated.
