I have a 2000 model 410 Searay, and the systems monitor display screen is cracked and impossible to read anymore. Where can I get a replacement display (just the part on the dash)??
 
Dealer unfortunately. They are rarely found anymore on other sites such as FP and ebay.
 
Took me six months to find one on eBay for $150. Dealer was about a grand, so I waited
 
Or go 3rd party and put on your MFD. Noland or Chetco. I'm leaning Chetco g2 to get all engine data on the network. All the monitor functions could be done as well. Big project though. The wiring is laid out in the manuals, so thats pretty easy to figure out.

I'm looking at it because my Tachs are off. New tachs are $600. I can get everything on the NEMA2000 network for not a lot more than that, plus add Transmission temps and pressures, which are major oversights on these boats.
 
Just find any dealer? Anyone know the part number for the Systems Monitor Display?
 
Local Marinemax service can probably quote if still available.

I am looking to replace the monitor screen on my 2006 320DA. I had two alarms go off this weekend, and could only read half the characters on the LCD screen. The part number for System Monitor Display on 2006 models is #1769722.

And, no luck searching current EBay or FP listings.

Was just quoted $1000 to replace the systems monitor with a new unit (hardware was $865, I believe). Since mine is somewhat readable, I'll live with it until the spring upgrade cycle.
 
When i've seen them on ebay the usual price is between $400-$500. $865 seems within reason for new, with the added bonus of a return policy that you may not have with ebay items.
 
I am in the process of having Vessel View 7 installed (next week) to replace the SmartCraft. I don't believe that will replace all the info available on the Systems Monitor, though. I'm a big believer in redundancy, anyway. :)
 
Hi, we replaced a serial data interface systems monitor (SM) with a parallel interface systems monitor. The serial interface is a complicated device that is similar to the original Seatalk.
With a parallel interface it is simple, you have to consider how switches operate, pump input are from positive switching, engine alarms are negative switching, this probably includes the genset. Other things that have to be considered is the engine computer alarm inputs are 5V DC, the SM is 12V DC so the engine alarms need two 12 to 5V DC voltage converters.
The basic concept is the 12 LED on the boat represent 12 inputs, each input is isolated from the other inputs, each input drives a common audible alarm and a LED , with ecception to the main ER bilge pump which is LED only.
So input signals are blocked and steered by diodes
There is also the LED test facility.
Negative engine switches operate in the wrong state and require an interposing relay to convert the signal to drive the LED with a positive signal. You wiĺl find the engine computer pulls the engine alarm switches up to 5V when the switch is open, thru a pull up resistor in the engine computer. This is to stop the input voltage floating. When an eng alarm switch is activated the signal gets pulled to gnd. The signal going to gnd will not operate a LED, hence the interposing relay. The voltage converters are fed from the ignition circuit, so engine alarms are only available if the engine is running.
We made the PCB from vero board, each i/p had a LED, test diode and LED current limiting resistor. Interposing relays are Finder brand, very small, single pole with c/o contacts. The eng relays were 6V, the genset relays if used are 12V.
It all worked, but there were some surprises
Out of 6 engine alarms only 1 worked, turned out the SM engine wiring had been hacked in the ER by others. Rewired all came right.
On this 34DA, there is no high bilge alarm float switch. The bilge alarm is basically the emergency pump, which turns off when the pump stops. I have seen Srays with the high bilge alarm. The SM is a generic part that was used over many models, not all alarms, not all are the same.
Spent long hours studying Sray electrical schematics, these drawings are absolute crap. All the SM wiring should be under the helm, but only the pump inputs worked correctly. The boats needs the high bilge alarm, but was not in our scope.
Cost was about $600 for parts.
Would I do it again, yes/no, next time I would use a PLC and just write a program. Much better way of doing it from my perspective, if I go to another boat, I just change the program to compensate for the variations.
 
I’m not sure, but I think you guys are talking apples and oranges. I believe the “systems monitor “ referenced by the OP is a proprietary device created by sea ray. The “systems monitor “ referenced by everyone with 2006 boats is the Smartcraft device, also named systems monitor. Two different technologies. The Smartcraft guys have it easy; either buy a used unit on eBay, or upgrade to the new VesselView. The guys with the SR display need to look on places like FP that sell old inventory.

That’s flounder pounder. They haven’t had it in a while. Best bet is marinemax for a new one and eBay sometimes for a used one.
