Free Yacht Chapter 4: Outboard Motor Mutilates Foot

Step 5 Water Pump Test

The water pump works great and the motor runs cool. I left the choke on too long and it got really smoky. The manual says to add one part two-stroke oil to TEN parts gasoline MINIMUM. That's some greasy gas. I couldn't believe it so I kept searching online til I found a site that said some of these motors can run on a leaner mixture. I'll try that if I ever run this motor much. For the time being I'll compromise and burn 16:1 and watch it carefully.

I believe that 10 parts gas is the most you can add. These engines are notorious for being considered 'gas lubricated oil burning engines' with their crazy mix ratios.

by "minimum," do they mean that 1 part oil is the most you can add, or 10 parts gasoline is the most you can add?
