I'm considering switching to electronic ignition modules for my '69
Evinrude 40HP. Replacing points and condensors is a nuisance. I can't
seem to figure out how the newer electronic modules actually function
(they replace the condensors and points). The timing and spark release
with a conventional point system, relies on the crank position to
indicate the appropriate moment to open the points and release the
spark. Timing is accomplished by rotation of the armature plate. With
the electronic systems there isn't a sensor for crank position, and I am
told the spark is released the moment the magnet on the flywheel passes
over the coil. Surely this must change the timing from the original
installation (ie. at idle, and throughout the throttle range). Has
anyone made the switch to electronics, that can provide me with a better
explanation of how they work, how easy they are to install, and how well
they work ?

Just curious.
