Ran our 2005 SUndancer 320, this past weekend, made it to our destination fine 25 minutes away, next day coming back ran fine, got close to port and beeping started, engine temp and RPM went fine but couldnt figure out what it was from, any thoughts?
Engine Beep

It could be any number of things and pretty much impossible to tell you what it is. You'd have to look through all of your gauges and the Smartcraft. Ideally get the computer scanned.
But... describe the beeping in more detail... there are different types/rates of beeping that may give us more info.
Did you check all fluids (including drive fluid, if you have outdrives)?

And has it continued, at the dock for example. Engines running when it beeps? Boat in gear when it beeps? etc.
The gauges at the helm all checked out. It sounded like a carbon monoxide sensor on my old 2007 Regal. I will have to go into the engine compartment and check out the fluid levels. I did change the Idle Air Control Valves the day before, but it didn't beep on the way out, just the next day on the way back after running about 15 min. After we docked, I didn't keep the engines running to see if it continued.

But... what exactly was the beeping like? Length of tone, number of beeps in a row, repeating pattern/etc.
Oil pressure was good, too?
Was it the CO detector in your cabin? What canvas did you have up?

One beep for a second or two, then off for a couple minutes then same beep again, ect ect. Oil pressure on both engines appeared to be ok.
The CO detector in the cabin was not attached (bought the boat 3 weeks ago) also driving to the destination the cabin door was open and, on the return, it was closed, not sure if that could've cause this.
Since the CO detector wasn't powered up, that negates that as an option.
The closest thing I can think based on that description of the beeps would be low outdrive drive fluid in the reservoir as that system sometimes produces intermittent beeps.

I thought the same, doesn't that boat have v drives though?
It could have either. Although I did bring up that question in post #2 and haven't heard the answer yet.....

I had a short-short-long sort of beep that drove me nuts. Every time we took off in the morning it would happen in about 10-15 minutes. No alarms anywhere on SC, bilge, nab electronics, etc. It turned out to be the bow thruster timing out and turning off. I found it when I manually turned off the bow thruster and noticed the same beep.
I also have a depth alarm and that’s what I thought this was. I would try turning off everything you can and see if the beep goes away. If it does, start turning things back on one by one.

I believe it has V drives. The sound of the beep is the same sound I hear when I turn the keys on at the panel in the galley before starting the enginesIt could have either. Although I did bring up that question in post #2 and haven't heard the answer yet.....
Based on how you wrote that, you sound unsure?
If you have v-drives, that obviously negates the drive fluid variable.
I am not 100% sure on the V drives. I will be going to the boat in the next couple days to investigate the fluid situation and see if the sound continues.
OK. Fair enough, thank you.
Excuse the question, but, are you comfortable with knowing the differences between v-drives and outdrives?
I am not, I have seen illustrations online, but I am not comfortable with determining the difference.
Sure, no problem. It's actually quite simple once you're looking at it. In a nutshell:
-- An outdrive boat has, well, an "outdrive" Meaning, big black things that stick off the back (transom) of the boat with propellers and you can tilt them up and down.
-- A v-drive boat, of course, has propellers - but they are tucked UNDERNEATH the boat, a few feet forward of the transom. You will also see rudders since, unlike outdrives, the props do not rotate for steering.
INSIDE the boat...
-- A V-drive has the engines mounted backwards. Meaning, an engines' serpentine belt is not readily visible as it's facing the back of the boat.
-- The driveshaft (that goes to the props) comes out of the engine and goes FORWARD to a transmission where the shaft makes a "V" turn and then goes out the bottom of the boat.
At the helm, for shifting/throttle controls:
-- If you have outdrives, you will have a total of two controls and they will be black.
-- If you have v-drives, you will a total of 4 controls and they will be shiny with, probably, golden knobs at the top.
-- An outdrive boat has, well, an "outdrive"
