want to upgrade a Mercruiser 3.0L from conventional ignition to a Delco EST. All the hardeware stuff of Delco EST is completely in place. Unfortunately I actually do not have any manuals.
Of course I experienced all the "problems" related - so the (+/-) confusion with the shift-break-switch, the resistor power cable, the strange "programming behaviour" of the Delco EST and finally the max. ignition angle of about only 20 deg assuming an adjust to have a smooth idle.
However, with the old and meanwhile defective (brokeen springs etc.) breaker points ignition it was always possible to adjust the ignition system to be fine; good idle and full power at the end of rpm-range. With Delco EST I have a significant decrease of max engine power and boat speed.
I read some posts here concerning this theme - now:
The manual 13covr2.pdf (http://www.boatfix.com/merc/Servmanl/13/13covr2.pdf) - some threads point to - only contains the table of contents, the rest is missing. Are there any other known locations for the complete document? Any other docs in this case concerned are welcome.
And is it possible to get a circuit diagram - not only a wiring plan for the outer wiring - for Delco EST? I even don't know whether or not Delco EST is built in discrete or computerized electronic ... That's it ...
Thanks, Ron the German .
