If that shouldn't work:
pinMode(9, OUTPUT);
pinMode(10, OUTPUT);
TCCR1A = (1<<WGM11) | (1<<COM1A1) | (1<<COM1B1);
TCCR1B = (1<<WGM12) | (1<<WGM13) | (1<<CS11);
ICR1 = 33333; // (16MHz/8)/60Hz=33333
OCR1A = 2500; // 33333*0,075 = 2500
This should produce 60Hz, 7,5% duty cycle at pin 9 and 10, but this code isn't tested.
I'm using the mode 15 from the datasheet (page 136):
