TOPIC: 1969 Merc 1250 - No Spark

1969 Merc 1250 - No Spark 10 months 17 hours ago #140502

New to me boat but have no history but looks like not used for a long duration. Has twin 1250 Mercs - 1969. Motors look very original....and pretty clean. Got one running after replacing a few rotted wires....only ran it for a short time as waiting for new impellers. Second one has no spark to all plugs. Checked all grounds, belt is good, disconnected mercury switch...still no joy. Have a working motor so exchanged coil, then switch box...still no spark. What next.....trigger? Is there a test for it? Looked around and don’t see any on eBay or a few suppliers I tried. Looks like CDI Electronics maybe had them in the past but not sure if they still have?
Would appreciate some guidance/ knowledge.....thanks in advance.
Any sources of trigger 2918A3 out there?

Looks like ED-MC found your post on the main forum and got you some good answers. I just wanted to be sure you got some Mercury people looking at your question in case some may not visit each forum. I will also save ED-MCs information for my own future reference.
