Gasoline/Oil Ratio
** On some light boat applications after the break-in is completed and the engine is being run at cruising
speed – between 4000 and 5000 RPM – the fuel to oil ratio may be as high as 28:1. This results from a re-
duced throttle opening with a corresponding reduction in fuel consumption.
