1974 Ski Nautique Firing problems

I have a 74 Ski Nautique and I just replaced the distributor cap, points, and plugs as well as a new arco starter. The boat was running fine before changing the starter but got to where it wouldn't crank when the motor was hot and eventually wouldn't crank when it was cold either. I put the new starter on and now it turns over perfectly fine but has no fire. I checked all my wires and they have power except the wire going from the coil to the distributor.

Any suggestions?? Please help!!

No voltage on wire going from - Negative on Coil to distributor? Check for flashing 12 volt test light while cranking the engine. The points may be closed and grounding out the Neg. side of coil as they should!!! Check point gap, should be .018 and that the points are opening and closing.
If gap is good and the engine ran before you changed the starter Do you have the correct starter for your engine rotation?
