I agree with Crosbyman, regardless of what it states on the motor or in the literature. Do not use 50:1 fuel to oil ratio. Please use 24:1 fuel to oil ratio. That is about 5 to 6oz oil to 1 gallon of gas. Your motor has plain bearings and there are ton of 3hp Evinrude/Johnson outboards that are prematurely worn out due to lack of oil. Yes, it will seem to run fine on 50:1, but its life will be short lived. Trust me, I am speaking the gospel according to AOMCI wealth of knowledge handed down through experience.

Use a good quality TC-W3 2 cycle marine oil.

Do not use 2 cycle oil meant for aircooled or weedeater motors.

The synthetic blends are biodegradable and produce a lot less smoke.

Here are a few examples.

Pennzoil Marine Premium Plus 1 qt. Synthetic Blend 2-Cycle Engine Oil

Evinrude Johnson Premium TC-W3® Mineral Formula

If you PM me your email address, I will send you an owners/service manual for 1968 Evinrude 3hp. It is the exact same motor except for the decals….lol
