I rented a John boat with a 15hp Yamaha several years ago. The fuel consumption rate was about one gallon per hour at wide open throttle.
The fuel to oil ratio for a 2000 model, 15 hp Yamaha outboard would be 50:1. Roughly 1 pint of 2 cycle oil to 6 gallons of fuel.
50:1
If not equipped with oil injection, use a 50:1 ratio, roughly one pint of 2 cycle oil, to six gallons of fuel.
