No spark at all

I have a 1983 4 cyl. 140 HP G.M. I/O Mercruiser and have replaced the points,rotor, coil and condenser and still can not get any spark what so ever. It turns over but that's it. Am I missing something???

How's the timing? Has it been disturbed? Any grounds off the mark?

i've done this also without knowing it i pulled the dist. out of its teeth that one took about a week to find because i didn't/don't remember ever letting it loose at the lock nut.

See if you have 12volts at the positive side of your coil,if you dont trace that wire back looking for problems.Also make sure the points are set properly,if they are gapped to close or wide you wont get proper coil saturation,and it wont fire.Is your rotor turning?
