Type of oil to use in 73 Evinrude 65HP

[MichealJames]

I've got a 73 Evinrude 65Hp Motor with 3 spark plugs and 3 carbs. It is a 4 Cycle motor? sorry, I do not know to much about boat motors. I was wondering what kind of oil I should get to mix with the gas? and should I use premium gas? Thanks in advance

I don't know of any 4 cycle/ 4 stroke motors built in '73 for outboards.
I believe you have a 2 cycle/ 2 stroke motor that requires 2 cycle oil, premixed to most likely 50:1 mixture.

If fuel lines have not been replaced with lines safe for ethanol fuels, you should be using, marine gas/ non ethanol fuel.

Good luck.
