In the US we say you use 6 gallons of gas (48 pints of gas) with a
pint of oil so that is 48:1 (or 49:1 in the final volume) but in
either case, close enough for a mixture that was arbitrarily chosen in
the first place.

I like the little bottles that say. "mix the contents of this bottle with one gallon of gasoline for 40:1 ratio" Takes all the guess work out of figuring "parts"

Just be aware they are not full. Don't just fill them up and dump it
in. I think a full bottle is 32:1 and they short fill them for leaner
mixes.
I have some of those bottles with a little compartment at the top. You
squeeze the oil up into the top compartment and dump it in. It is the
right amount of oil for a gallon of gas.
One is 32:1, the other 50:1. That takes care of all of the yard tools
I have.
It has been a real long time since I used premix in an outboard, my
Merc 75 had injection but when I had the 1974 era 40 I used the pint
cans. I bought them by the case.

That's 1 pint oil added to 6 gal gas. Do your self a favor and only use good
oil and high test gas.

The short answer to your question is 'yes'. To get a 50 to 1 ratio with 22.7 liters, you would mix
in .454 liters of oil.

Amen.

Don't bother with high test gas... it could cause cause starting &
idling problems as there is usually an additive package included that
just isn't required for an outboard. The minimum octane rating for 1973
Evinrudes is 80.

The required oil is mixed 1 part in 50 to the gas (1 pint to a 6.25
gallon outboard tank - yes there is a little extra room intentionally in
OMC tanks) and the engine requires TCW-2 or better oil. The oil cost is
such a small percentage of the operating costs with a boat, so don't be
unnecessarily cheap... get the good stuff (name brand, eg., TCW-3) by
the gallon for economy (will serve 8 full tanks)

A little extra oil is OK (my portable cans are 5.7 gallons, so I put a
pint in to mix up boat gas) but don't run it any leaner.

Is there oil port and if so where and it says use premium gas with 50:1

Not on a '73 anything two-stroke that Ive ever seen You're better mixing 30 or 40:1 with an old outboard and use premium fuel. I've seen too many scored chainsaws and weed eaters because someone tried to stretch the limits on 50:1/ even with the finest synthetic lubricants, there's no room for error at that rate. Best to mix thicker to the engines specs, than to read some wild claim of an oil manufacturer.
