225 Merc fouling plugs

Out on the water at a fast idle motor started skipping checked plugs, 3 were wet. Put in 6 new ones. Fired it up same problem except 5 were soaked.

Could be a bad/intermittent CDM(spark plug coil).<br />1 for each spark plug.<br /><br />Use a auto timing light to view the spark to each spark plug.<br /><br />Been there, troubleshooted that.
