The knock sensor has a brass Y-fitting for both the sensor and drain plug
I need the Brass Y adapter
I Can't find it or a part number.
not sure if it's a Mercruiser part.

Found it.. 22-806705-1 $95 Rip off...
The Knock Sensor has a different Thread ( fine) that blue drain plug.
so its not so easy to replicate..
i think ill get a plug and take it out of the block and try to EZ out the rest of the knock sensor The boat is in the water so it adds a little stress to the work...
