The oil injection system installed on the 2002 model, varies the amount of oil supplied to the engine, according to RPM range. Simply fill the oil tank, located on the engine, no mixing with fuel required. If the oil injection system has been disabled, mix the fuel at 50:1 ratio, one pint of 2 cycle oil, to six gallons of fuel.

I would assume there is no oil reservoir in that motor. The oil is mixed in with the gas each time you fill the tank. There is probably lubricant (oil) in the lower unit gearcase, but I don't know the procedure for changing that.
