The horn works fine for me. I was just looking for a CEL for the systems the horn doesn’t sound for. ie- injector faults, etc.
Guess that’s not possible based on post #2?

I'd like to install a dash mounted check engine light. My motor is analog and pre-smart craft. The warning horn only gives so much info and the horn doesn't sound for all...
Could also be the fuel diaphragm but check the tracker first. Installing these diaphragms can be really tricky. Take your time and get the special tool. If u screw up, the diaphragm will be toast...
Without gauges you can check for fuel as Don mentioned on the air side schrader valve. If there's fuel you can check the fuel reg diaphragm. Gages are a big help though. A little research and you can...
Elaborating on my first post: Good spark on all 6, Fuel system professionally cleaned/tested, good compression on all 6. However, Installed new plugs, 5 cylinders burn looks identical. Cylinder #5...
Not sure I need the whole powerhead. The rest of the motor checks out ok. Thanks for the reply.

Regarding the ECU Injector drivers: Are these paired (similar to the old EFI's). Does 1 driver control 2 cylinders?
Also, If anyone has a known good ECU (858891 16)...
There aren’t many options around here. Which is why I try to do everything myself. The other merc dealer said it’s too old and they don’t have the software to support it anymore, blew me off...
No, this was with the engine key on just to scan. Engine was never started. He referred me to another merc dealer 2+ hours away for any more detailed analysis.
529830Attached is my data. With my old ass motor apparently I only get a total fault count history. The motor has 434hrs. No injector faults, ever apparently so I guess I’m back to square one here...
I Appreciate the heads up. That’s great info regarding the reeds. I had the intake off this spring and inspected the reeds. At that point they were ok. Depending how long this saga continues; I may...
Tracker diaphragm install verified, 100% perfect. Let's hope it went back in perfect too.....I'm waiting to check the fuel dia until after the scan. Too risky pulling these diaphrams in and out. Will...
I found a shop that will scan my motor. Options are very limited where I live. While waiting for this, I will pull the diaphragms again and inspect them maybe also swap the AI. Thanks very much for...
Reeds are Chris Carson. Pulse pump rebuilt but the old one looked fine. Approx 350hrs. I’m guessing #3 injector is flooding based on that plug being dirty and the rest looked fine. Hopefully a scan...
Compression is 100psi on all but 1, that is 110. Didn’t do a leak down. Motor ran great last fall. Ran ok this spring but it’s getting progressively worse. I have a service manual and have checked a...
No liquid fuel at the air Schrader valve. The motor is barely starting now when cold. Multiple starts, and stalls to get it running then super rough running until it’s up to temp. Once warm is stays...
I will check the air port. In the past I’ve seen diaphragm leaks in the the pressure testing. I also noticed yesterday when I pulled the plugs thatv#3 was dirtier than the rest. All looked identical...
Another observation: tiny bit of oily residue on the water. Makes sense to me with the extra fuel but I thought it was worth noting.
Any input is helpful. I was very careful with the diaphragm installs. The fuel diaphragm I did last summer. Last fall the motor ran great. This summer it’s gotten progressively worse. It acts exactly...

The onboard boat oil tank is 1/2 full. Both caps are tight.
Thanks Don!!
Saga with this motor continues. The rough idle stall , smoke nonsense continues. Tracker didn’t fix it. I have narrowed it down though. It’s only happening on a cold motor. Once the...
So, I removed and reinstalled the air diaphragm. I cleaned a tiny and I mean tiny amount of corrosion from the screw side of the metal cap. Next to nothing but I figured things were gonna be clean...
