2000 Cruisers 2870 Check Engine light blinking but no codes?

[CLi87]

The check engine light on the console starts slow blinking steadily immediately after starting the engine but when I checked the codes in my Mercruiser 7.4 MPI it just gives me code 12 which should mean system is operational and nothing is wrong? Any idea where I should check to get the check engine light to stop blinking so that when something really is wrong then it'll blink

In some older GM-based diagnostics, Code 12 can refer to a distributor signal interrupt, but on modern MerCruiser MPI systems with smart alarms, it is almost always related to the drive lube monitor

My drive lube level is fine so I'm guessing it's not that, what would cause a distributor signal interrupt?

Just because the level appears to be correct, doesn’t mean the circuit is functioning properly. Floats get hung up, rodents chew on wires

Never guess …always test
