Timing Mercruiser 305 5L

[Anthony200482]

I am trying to set the timing on my 1991 mercruiser 305 5L but I do not have the wiring diagram. I know that on GM SBC you have to disconnect the tan wire to bring it to zero, but there is no tan wire coming out of the ICM. <br /><br />Does anyone know which wire to disconnect when setting the timing or does anyone have a wiring diagram for the ICM and Distributor? Any help would be great. Thanks

Mercruiser is not an outboard, Anthony.<br /><br />I will move this to the Mercruiser forum.
