Hey guys, looking for some input on the ignition module on my boat. The motor is a 1995 454 MAG with a carb. Currently have the 806745-3 ignition module installed on the boat, Im wondering if anyone can tell me the timing curve on this module? I dont see anywhere on the module were it says V-8 20, or V-8 24.... Just trying to figure out what exactly I have on it for timing purposes. (installing a procharger when the boat comes out of storage in the spring) I cant seem to find any information at all about this module online as to tell me what it is either.

Thanks for any help!

See here for more info:
Thunderbolt V Ignitition

Hey SB, thanks for the quick response! I read threw that article, Im assuming I have the Thunderbolt V system as I have the knock sensor piggybacked onto the ignition module. Lots of great info in that article regading setting base timing and putting the system in base timing mode. I just dont see anywhere in that article at all the total advance for that specific module that I have on my boat currently, and thats what Im looking for. Seems the information is hard to come by.

Its hard to read because its small, but in short
10* advance on acceleration
10-15* advance at cruise speed

This is from base timing of 10* so total timing = 20-25*

It’s there.
Read all if it.
Do not miss any of it including graphs/pages from mercruiser included in Post #8.

Thanks AllDodge and SB, reread the article and I understand it a little better now. So this system is not like the Thunderbolt IV setups at all with the different modules I was referring to from what Im reading in that article? This system works with the knock module to control overall timing as well from how I read the graph. Just trying to figure out the timing for the procharger installation
