Carver Owners Forum

Hi. If anyone can tell me what this three beep alarm means. I will explain circumstances.
I have a 396MY - 2001. My engines were starting perfecting until approximately a week and a half ago, when my port engine decided not to start. I have the push button run/start/stop keypad for my engines. Normally you will get a loud beep, which sets the engines ready to start. I receive that on my starboard side motor, but not on the port engine. Let me explain just a little further. I was able to start my port engine a week ago Monday. It ran for 30 to 40 minutes. Everything was fine. I turned it off. It will not restart, although I tried it about two hours after running it.
What I have found out this week, after trying to start it again, is that while I was away from the boat during the week, there was an audio alarm going off every two to three minutes with three continuous beeps. I know it is not the FireBoy or the CO monitors, since we went through and disconnected them. The sound is coming from the dash where the keypad is for the port engine. When I turn the power off to the engine (port side), the beeps do not occur.
Does anyone know what the three beeps means? It must be a code/alarm.
Any help would be great. If anyone has a list of the codes that the beeps mean, that would be fabulous.
I have Horizon 8.1 engines in a 2001 Carver 396MY.
Thank you everyone for your time in looking at this post. I appreciate it.

Would be good to post your engine serial number so we can see exactly what engine and ECM you have.

Viper -
I am going to the boat over the weekend. I will get the information and post it.
Thanks again,
Tom

Wow. Those are a couple great documents that any Merc owner should have on the boat. I don't run Mercs, but have many friends that do and have always heard questions about "what do those beeps mean?" Now I'll have some answers!!

In this case I believe he will still have to get someone to hook up the the onboard engine diagnostics to decipher what is going on and where it is from. I think he will have the 555 but we will see for sure when the #'s get posted. In any case they are pretty standard to some extent although I am concerned with the sets of three.

Viper and Bud:
Thank you once again for your help.
Below is the serial number on the port engine
The year, make and model is the following:
2001 Carver 396 MY
The port engine serial number is: 0M026988
The boat is powered by twin 380 HP 8 Cyl inboards.

I contacted Cape Harbor Marine in Cape May, NJ to see if I can schedule someone to come out and put computer diagnostic tool on the engine to see what codes it is showing. Hopefully the diagnostics will solve the issue.

I will keep you posted on the progress.

Thanks again,
Tom

I have uploaded a few photos.
The photo of the keypad ignition is from the starboard side.
The other photos are under the helm area. I removed the plate and took photos of the unit and the wiring. Lots of wires.
Hope these are helpful.
Thanks again,
Tom
