What are the symptoms of a bad ignition module in a 500efi?

Anyone know the correct part number? Was looking on line and there appear to be a few different ones. It would be going on whippled 500efis.

The pick up module in the distributor??? Most of the time, they just quit or will quit when they get hot

Current Merc part#:

I believe (but don’t quote me) the AcDelco is this:



Remove old grease from pad module is mounted tooUse thermal paste, not the improper dielectric grease that comes with them. Put on extremely thin.

miss fires on this system are most often the pick up coil and where it connects to modual they corrode and lose contact put a goooood new pick up in around 25 bucks

Mine would make a miss and not get above 3000 RPM's when it got hot.
