No Fire

[The Job Site]

We got stuck out in the bay today when I went to fire up the motor. After much trouble shooting we found out we had fuel but no FIRE. 1989 200 Hp Mercury Black Max is the motor. We have no spark on any plugs. We checked the fuse and its ok. We then unplugged the main wiring harness connector and tryed to get spark buy jumping the starter with a screw driver and checking the plug wires for spark. Please help my money is running low
