Default Stumped on alarms

I have a 04 Maxum 2500 se sport. I keep getting 2 beeps about 5 minutes apart (any rpm). Water temp is 175 and good oil psi. I canít find an engine manual so if someone has a link to that it would definitely help me. Iím hoping someone can guide me in the right direction. Right now I feel like Iím on ghost hunters.

Welcome aboard

Under Documents of this site there are Mercruiser manuals and you should be able to find the one for you engine. The computer may have the fault stored in its log so if you have a mechanic have him scan for fault codes.

I read some forums and when I get home today that’s the first thing I’m gonna check.

Did you get anywhere with this? I have same problem. 2 beeps every couple of minutes. Had a guy hook computer up to boat computer and there were no error codes. Leaning towards the ECM is getting glitchy.

Nope! Dropped the boat off yesterday to get put on a computer. It acts like it’s in limp mode and starving for fuel. It won’t go over 3600 rpm and should be 4800 to 5000. 2 weeks prior the dry impeller went out and I had a new one put on. I’m hoping that when the heat temp went off it threw it into limp mode. Hopefully I’ll find out soon.

Yours sounds worse than mine. Mine runs fine, for the most part. Like I said the computer hookup didn’t find any errors but the readings were a bit wonky at first. But once he reset everything all the numbers checked out. I can actually get the alarm to go off if I shut it off and restart it a few times. 3rd time is usually the charm. So it’s almost like the computer just is glitching or something.
I also have an issue restarting the boat after running it at operating temp. Like if I take it out and go get gas, it won’t restart after fueling. Same if we drop anchor for a bit. Have to put throttle in neutral and “floor it” to get it to turn over. I’ve been every road with that one. Not a “vapor lock” or fuel sensor... This also why some people think it’s time for a new computer. We’ll see.

I don’t have any starting problems and it runs fine just won’t go over 3500 rpm and that dam alarm. As far as your boat try turning the key on a few times to see if it starts better. It could be a weak fuel pump. Is it mpi? Mine is.

Yes, I’ve got an MPI.
I just hung up with mercruiser. They’re super helpful by the way. I call them all the time. You might want to call and get an opinion. *(920) 929-5040‬ Have your engine serial # ready.
He basically said don’t buy a computer. They rarely need to be replaced. He also said don’t reprogram them. He told me a mercruiser certified guy needs to get his computer on there with the right software and “delete” that alarm once it’s ruled out that it’s nothing. Otherwise it’ll never go away. He also doubts my restart issue is computer related. The last guy I had there with a computer wasn’t mercruiser certified. But the guy I’m having look at it next is. I’ll update you.
I was thinking about your RPM. I rarely have my boat over 3700. That said, mine could go higher if I wanted. Sounds like yours won’t. I’ve got 2900 scr with only one engine. It often depends how many people are on board and how many beers they brought! But using the trim tabs I can get her on a plane at around 3500. Anyway... I’ll be playing the tunes loud this weekend to hide that alarm

When youíre having this problem does the engine not crank or crank but not start?
