1998 challenger New Stator and trigger coil, no spark.

I just recently removed one of the engines from the boat. I pulled the flywheel cover and found out that water was getting inside of the area. The area was completely rusty. I pulled the flywheel and removed the magneto to clean everything. I also wanted to install new gaskets for the housing and cover. I then put everything back together and put it back in the boat. After hooking everything back up, I proceeded to try and start it with no luck. Turns out there is no spark. To try and make a long story shot. I ended up putting the non running stator/trigger plug wire in the working engine, I switched the spark plug wires and starter wire to. Bingo it fired up with all the wiring from the non working engine. This tells me that all the rest of the parts have to be good in the boat, which I am happy about. It has to be what I installed or something i did, which I am not so happy about. I did buy a cheaper stator package that came with the stator, pickup coil and plug. It almost looked a little smaller, also the bolts that hold the stator to the cover were very tight to put in. Basically i had to thread them all the way through the new stator. I also noticed the plastic ring that pervents shorting to the stator bolts was not on the new one. I did compare them and even counted the number of coils and it matched. I am thinking either DOA trigger coil or flywheel is not far enough back causing the raised spot on the mag to not be in the right possition. I did forget to sand the raised part on the mag though. The flywheel had a notch on the crank and I did put a mark on the mag when I removed it. Not sure what to do next.

I wish I got pics of the new parts.

It also says it's a direct replacement for the boat.

Hi, I also purchased a cheaper new stator on ebay. It also had the holes too small and it also did not work at all, no spark. I switched it out for an old used one and engine fired right up.

I think I found the issue. It looks like the trigger coil mounting bracket sits to high causing there to be to big of a gap.

Well that was the issue. I tested all the parts on the aftermarket stator and they all tested good. The trigger was 251.2 ohms and the 3 yellow stator wires were all. 5ohms each. I tried moddifing the new trigger to fit the original bracket which looked promising. I didn't want to modify the bracket because I had a stock trigger that I wanted to use as a backup. I was even able to get the engine to fire up. Then the engine did not start again. I took it back apart to find that it must now have been to low, the raised part on the mag hit and knocked it off. Put the stock trigger in and it works great now.
