I feel for you, been in repair mode since 6/5. Bravo coming off in morning, hope this is it.
Not even pissed. Way past that. Just disgusted.

This guy John is good.

 

He's the guy I called and seemed like he knew what was going on, but couldn't find anymore info on him. I may send it to him if this new one works, have him fix it, and sell it on flea-bay.

 

I'm going outside now to say nice things to my old Alphas, 5.7s, Carter carbs and Thunderbolt IV...

 

Hell ya! Simple 7.4, carb, no alarms, no self diagnostic codes.

 

At one point, my dad was talking about updating his '73 Buick Riviera 455 with the then-new Holley throttle body fuel injection and electronic ignition in the interest of getting better fuel mileage. He changed his mind when I piped-up that when it died on the side of the road, I could always get the old equipment running with a rock and baling wire. Not so for the "new-fangled" electronicals.

 

My take is i love it all on my cars. Not so much on a boat. All the corrosion and such, simpler the better. I read threads every day about this IAC, that manifold pressure, this code, that smart-something. No thanks.

 

You can have my V8-22, I don’t know what a working ECM sells for on fleabay. I’d love to remove all the wires and it. I’m looking for a reason to get a new DUI.

A complete DUI kit, plug wires, clamp, and wiring is about $400. 1/2 the cost of the new ECM

 

DUI kit! Does it come with lawyer? My last one was $1500.

 

@Pirate Lady, you beat me to it!

 

Lot of these manufacturers are starting to get wise to the other industries inhibiting owners of equipment from fixing their own stuff....adding layer after layer of proprietary tools and electronic diagnositic equipment that only a shop would realistically have access to. to repair. This is the other direction to built in obsolescence...equally as underhanded and insidious

Consumers need to stand up and boycott companies going down this road and praise those that are not.

Seriously?

 

Well, Mercury sent the incorrect ECM. It was for a 5.7mpi Bravo, however it seemed to eliminate the issue I was having, although the motor was running extremely rich. New one won't be here until Monday.
My marina isn't happy, although Mercury will return it, they wanted them to fork over another $1500 for the correct unit until they get their mistake returned. So in the hole for $3K.

What is it with these companies anymore? They screwed up; let them take the chance of being out the $1500 if you were "lax" in returning the wrong unit they'd sent you. At least they're sending you the correct unit.

Recently, I bought a replacement headlight from CARid for a late-model Mustang (an $1100 item!). When it arrived, the box looked to be a bit compromised. While the headlight looked okay on the outside, there was something loose internally when rolling the assembly around in my hands. I called their help line with my concern and they overnighted a new assembly to me, didn't care to see any of the pictures I had taken, and didn't even want the "bad" item returned! Amazing! Hello, Mercury!

 

Finally got out to test it. Been busy with work and was told by the marina that during their tests it seemed to clear the problem with this new ECM. Took it out today - no joy. It has actually gotten worse. Now it is trying to shut down at higher rpms as well.

I’ve been reading about the Crank Position Sensor possibly being an issue. In the older MPI motors like mine, when the sensor goes bad, it doesn’t trigger Guardian Mode or produce any codes. The computer just gets confused on the engine timing. I may throw that part at it. My marina and myself are at a loss at this point.

Of course the CPS is a $200 part from Mercruiser, but I’m assuming I can get one for a GM 5.0. Maybe from NAPA? There’s isn’t any magic to it other than being a magnet. Now I just need to find one so our Summer isn’t completely bungled.

 

Maybe? https://www.autozone.com/engine-man...eyWord=chevy+50+crank+trigger&fromString=search&isIgnoreVehicle=false&year=1950

 

Just found one at NAPA and heading back. Fingers crossed but not hopeful.

 

Ollie, I feel your pain. I lost the entire 2019 season, and the first part of 2020, due to my marina destroying my windshield and piss poor customer service from Taylor Made. Taylor Made ended up making good, but not until I got around their customer service department (the only positive to come from COVID) and talked to their engineering guys. When they heard I had been waiting for a year for a windshield, they jumped into action and had one made and shipped in less than 4 weeks. Good luck, I hope you find your answers soon.

I had the ECM die on my 240 Sun Deck with the 5.7. Fortunately it was just that, the ECM died and replacing it fixed the problem.

 

Got a contact at Taylor Made? I've been trying toi get my lockset replaced for a year now. Ollie, sorry to hijack. M

 

Only in the windshield division. They don't seem to share a lot of resources across divisions, expect a piss poor customer service group.

 

Update: Been running multiple rpms (no load) for 45 mins with the new CPS. So far no issue. Need to grab my 1st mate and try it outside the harbor. I’m going to be happy and mad at the same time if it turns out to be this crank position sensor. Still not confident.

 

So rolling the dice didn’t pay off. Turns out it is the CPS, a $75 Napa part. Well, at least we’re up and running.

 

Glad to here you are back on the water. For future reference, CKP = crankshaft position sensor, CMP = camshaft position sensor. Now, go get some salmon.

 

They have salmon in Minnesota? I thought that was PNW?
