I just asked a guy from the O'Reilly Auto Parts store who knows a lot about boats. He told me to mix it 1 pint to 6 gallons of gas and to use Quicksilver.
50:1 or 16oz of oil to 6 gallons gas
A 175hp Mercury outboard requires a 50:1 fuel to oil ratio.
If not using the OEM oil injection system, the fuel to oil ratio for the Mercury 150hp XR4, is 50:1. This is roughly, one pint of 2 cycle oil, to six gallons of fuel.
