This topic caught my interest, and the timing was good for ordering new modules during the rebuild of my 912UL powered K3. I did not suspect damaged wiring at the connectors, but they are almost 30 years old now so why not refresh.
While trying to get up to speed on ignition system refurbishing, it occurred to me that the potential vibration loading on the 100hp on straight floats would be far greater than an 80hp on wheels. There are no brakes on floats, and the 100hp wants to idle higher. So, maybe this exercise was not required – oh well, it will feel nicer to be up there with newer equipment.
