Testing my 1980 75hp Evinrude

[TNStream]

I’ve got a bogging symptom after 2/3 throttle!
Tested my trigger and white to purple 18.4-18.0, white to green appears open, white to blue 18.3-18.0?
Am I correct that all should read the same?

Does spark jump a gap of 3/8" on each lead?-----And is compression around 135 / 140 PSI ?-----Exhaust manifold gaskets are known to leak water into the cylinders.

125 psi on all 3, spark appears good, it starts and idles fine, it’s when you get above 1/2 to 2/3 throttle it bogs and acts flooded.

Check fuel pump diaphragm.

New fuel pump.
I have checked CDIs site for specs on trigger and it says for this motor checking all 3 with white being the common, you should get 35-45ohms. On YouTube checking all 3 with white 18.4ohms ??
Any clarity would be appreciated

If you have spark on all 3 cylinders trigger is good
