My understanding is the driveline harmonics are what trigger the knock sensor. It is possible to have the sensitivity of the sensor altered, although it has to be done in the ECM.

Which set of holes is it installed on ?
( top, middle, bottom)
I'm assuming the U-joints in the box are in phase ?
This spring when I installed the drives, I even phased
the outdrive u-joints with the u-joints in the box.
I use to have a small vibration that you could feel in the floor of the boat at certain speeds, since I phased them, I cant feel it.
It's not that big of a deal to do.
Merc recommends doing it on their jackshaft ( forward
stagger) models.

It is dropped off again at the mechanic and hopefully it can be a quick fix for him. I hope buy scanning it is something small like the IAC or something.

So the engine was scanned and nothing come up. Still unsure of what the issue is. Due to rain he has been unable to water test yet. Could it be something as simple as the engine having been fogged too much during winterization? I filled the tank with 93 Octane to bring up the octane rating of the old fuel but the old fuel had been stabilized. I am going to change plugs, anyone know which ones work best off the top of there head?
As far as the water leak, he said there was a clamp loose on a water line in box so he seems to think that was it but still, no water test yet.
