Coil Replacement/One,Two, or All

[FillupD]

I have a 1977 85hp that has silicone covering some cracks in the coil windings. (I assume they are cracks?) I am going to replace a couple of them.
Is it a good idea to replace all coils at the same time?

if they are cracked they are going to fail, exactly when? i don't know. the most inopportune moment, no doubt.

Thanks,
Two seem to appear to be in perfect condition and I will replace the other two. I just wasn't sure if this would throw the spark strength off to make it run funny.

will probably improve the situation.

Replace the two with the cracks, take the others to your local OMC/BRP dealer and have them tested. If they test OK, slap them back on the motor and go boating!
