Coil Pack Question

[Blue Fin 135]

I recently purchased a 1973 135 Johnson. It came complete with a bill from last year for $1800 from a good local repair shop. One of the items on the bill was that one of the coil packs was cracked and was replaced with a new one.
Out of curiosity I examined the other three, and can see small hairline cracks on two of them.

Now to my question, the motor runs like a champ so I know they are working. Is there some sort of epoxy or other sealant that I can apply to prevent these cracks from getting worse? Or am I just wasting time with a stupid question?

To make you feel better you may want to paint the cracks with black neoprene dip or liquid tape. This will help keep the moisture out but when those coils break down and start to leak to ground, they will no matter what you put on them. If the mtr is running good, run it until you have probs.

Bad ignition coils are known to cause direct damage to powerpacks. If they are not in good condition they should be replaced,

What makes them bad at this time because they have some facial cracks. I've seen a lot of them run a long time like that.

Not much risk with magneto ignition...but with with the cost of power packs vs coils, it's an easy decision...

Re: Coil Pack Question

Thanks for the advice guys.

I am going to take a grain of salt from everyone. I live in Winnipeg Mb Canada( if you look at a map of North America, look at the great Lakes, then look up a little and to the left, the large lake is lake Winnipeg, Great river system on the bottom and the lake is by sq mile bigger than the 2 smallest great lakes) So my open water season only has another 60-70 days left, after that when I want to fish I load up the 4x4 and drive out on the lake.

So my plan of action would be to seal the cracks with a high heat epoxy I managed to get from a friend. then over the course of the winter purchase new coils that can either be changed out in the spring or at the very least kept in the tool locker, to be changed out in the event of a fail.

Thanks again for the help. This is my fourth post asking for words of wisdom, and all have been replied to and worked out...thanks
