New Boat owner 1989 Merc 5.7 260H

I have used my boat a few times this year and it seems to be missing a little therefore I thought I would change my plugs, rotor and distributor cap to see if that fixed the problem. While pulling the plugs I noticed one of the plugs was cracked therefore that probably caused my missing problem.

I decided to change the distributor cap and rotor since I was at it, I had an issue getting the rotor off it was rusted/corroded on therefore I had to brake the old one to get it off, I also sprayed it with silicone trying to break it loose. Got it off, cleaned it up put the rotor on, put the new distribuor on.

I now can not get the boat to start and I does not appear to have any spark from the coil... Any suggestion what could have happened.

I also change the water separator but I can not believe that would have anything to do with this.

Please help.
