9 - All You Need to Know on Delco EST Marine Modules

In this video I discuss more info on Delco EST Marine Ignition Modules and specifically how to use them on just about any engine.

Correction: At the 11:10 mark I mention that Mercruiser V8 engines use 10 degrees as the base timing setting. Actually most of the V8 engines I’ve worked on use 8 degrees as the base timing setting. Adding 8 degrees to the 22 degrees from the chart gives 30 degrees total timing which matches the total timing of the 5.7 Delco EST curve. That means you would just use 12 degrees as your initial timing setting straight from the chart.

For a detailed understanding of how the timing tool works I’ll refer you to another video I did a couple years ago.
