Usually caused by a faulty timing sensor in the timer base under the flywheel. Check your manual for the proper ohm reading of the sensors. One fire the port bank, the other fires the starboard bank.

The whole timer base. Take your timer base leads off of the pack on the side that has spark and transfer them to the side that doesn't. If you have spark then, it's the timer base. If not it's mostly likely the pack. Or two bad coils, but that's unlikely.
Thanks guys for your help ran the test as boobie said seems I will need a new timer base this is not a cheap fix anyone know where to get one for a decent price?
An engine that old..... good used timer bases should be plentiful at dealerships and the regular outboard repair shops for a small fraction of the new price.
