I have looked at some of the connector ends. So far everything looks like new. Its a 12 year old fresh water installation. I'll keep looking. If I want to try a termination resistor where does it plug in? Maybe there is a "Y" connector behind the dash the Murphy installed in. Have o look.
Makomarrk...I have a couple other issues with this pair of engines. Maybe you have experience. The engine sync function does not work. After a run on the lake one engine wants to "hunt" at idle speed. I'm wondering if I have a bad ECM, throttle position control motor or something. Hate to go to a repair shop to get a computer diagnosis. Thinking of buying a Diacom computer interface that is supposed to be able to see all the engine parameters and fault codes. What d yo think?
