1958 Johnson 18hp ignition coil

Is anyone familiar with CDI Electronics? Good bad or just cheap?

I've been using cdi coils for about 5 years. I've installed about 40 of these with no issues I know of.

If you go down about one thread you will see an answer there.
OEM coils are made with the correct radius to give you an almost perfect air gap vs the "will fit" coils.
Make sure this engine is run on nothing less than a 24:1 mixture. Will last a lifetime this way if taken care of properly.
Also am hoping you are changing the impeller as well...... Check gear oil for water.
In 1958 they went to the smaller 10hp style gearcase minus the large rear bolt. Good gearcase but not quite as heavy duty as previous years.
