What is the proper fuel to oil ratio for my old outboard?

Posted on July 2, 2012 by mike.donovan

The currently preferred fuel is Regular gas. All pre World War II non-racing outboards can operate safely on a 16 to 1 (1/2 pint per gallon) fuel/oil mixture using modern TCW 3 oil except higher (25 hp and up) use 3/4 to 1 pint per gallon.
