QSB 5.9 Low Coolant Alarm Sensor
This topic has 1 reply, has 1 voices, and was last updated by
1 month ago March 2, 2025 at 4:04 pm Corey/Tony Here is an update to a question I had a few years back when I installed and began running the 480 in my lobster boat.https://www.sbmar.com/community/topic/low-coolant-sensor-on-new-qsb-5-9-480/ When starting the QSB I get a “low coolant” alarm through the SMX panels and there is no way to shut off except for shutting alarm to OFF on the SMX system. Low coolant alarming is not my my biggest concern but nice to have a sensor…

SMX Seaview Display showing wrong engine hours and voltage
This topic has 1 reply, has 2 voices, and was last updated by
2 months ago January 20, 2025 at 8:52 pm I seem to have a problem with one of my SMX Seaview displays. For some unknown reason the SB display started showing low battery (0.6 v) level, and the engine hours dropped from 1600 to 537, which I believe may be an error code (attached image). I checked all cable, but looking at the diagnostics page for both displays (attached image) I noticed the voltage input on the SB display shows about 12V, but the battery still reads 0.6 V. I have also t…
1 ReplyJanuary 21, 2025 at 11:03 am Let’s try to reset the screen before doing anything else… Hold down the far right key to enter the menu, then navigate to SYS CONFIG > RESTORE DEFAULTS > then press RESTORE DEFAULTS on more time until you hear a long BEEP. Then exit out to the main screen and see if the voltage re-appears correctly. Let me know, Corey Corey Schmidt | VP, Operations | Seaboard Marine, Inc.Last Post by:

January 15, 2025 at 2:57 pm I went out fishing the other day and we hit a wave that gave us a pretty good knock, that’s when I heard my alarm go off and looked at the warning lights and saw my WIF (water in fuel) light on. which I had cut the ends off of almost a year ago when I pulled my Racor to rebuild, shortly after that all my warning lights came on my low oil, low voltage, and high temp. My gauges were still reading fine but I stopped the boat to check it out a…

4 months ago December 10, 2024 at 1:26 pm During routine logging of my Onan generator I initially noticed that there was a difference of about 1100 hours between the hours shown on the generator display and those in SmartCraft VesselView, I didn’t really pay much attention to it, a few months passed and now after some time there is no connection and the display is not showing me any operating data only from the generator. The data from the engines can be read without problem. I al…

Replacing Starter Battery

February 7, 2021 at 3:21 pm Hi Gang, My “official” first post, but I’ve learned a ton so far just by reading previous threads. My boat has a 6BTA 220hp engine. The specs call for start battery with 1188CCA and 160min reserve. I’d like to replace the large 4D battery with something smaller and am considering 2 Lifeline G24 batteries (GPL-2400T) wired in parallel. Does this make sense? I’d love to be able to use just a single Group 31 battery fo…
7 RepliesDecember 2, 2024 at 9:26 am MRBF fuses rated at 300A seems to be considered okay by some, the engines start up very fast so unlikely to hit fuse trip point, but I wonder about extended cranking such in case of fuel issue. MRBF is very convenient, but if I wanted higher 500 A then have to go to ANL and holder vs MRBF and cable straight to starter.Last Post by:

Smartcraft WIF 428 Alarm Question
This topic has 1 reply, has 2 voices, and was last updated by

November 2, 2024 at 7:13 pm I believe I have a bad WIF Sensor which I am going to look to replace tomorrow on my 2007 QSB 5.9 370 hp. I am getting a 428 WIF alarm. Alarm sensor has gone off on about 3 or 4 times during the last 10 outings, and none of the last four outings until today. Went off after about 30 minutes of running at the dock, then went off for a minute, back on for a minute and then didnāt come on again until we started the boat a few hours later when we wer…
1 ReplyNovember 4, 2024 at 11:43 am No one yet? I don’t and never have had a WIF alarm but if I did I would add an ON/OFF switch to stop it. Maybe not the best idea but sometimes alarms must be disabled temporarily.Ā Ā Just be sure it is enabled when the repair is done.Ā Ā Ā Build or buy a wee enclosure to house the switch so it cannot inadvertently be defeated. My ideas. Or ask the mfgrs. And do the repair so you don’t have to depend upon the switch.Last Post by:

Using J1939 instead of SmartCraft for Garmin?
This topic has 7 replies, has 3 voices, and was last updated by

August 23, 2024 at 9:12 am I am wading through the process of an electronics upgrade for our 2007 trawler. Escape has a single Cummins QSB 380 and second generation SmartCraft. For a variety of reasons, I am looking at Garmin electronics. Integrating engine data with the Garmin MFDs meant using their $600 SmartCraft Gateway until I discovered that the gateway does not have a variable for total engine hours. Turns out engine hours are available over J1939 and that opened a…

SMX Digital View without the Display?

September 29, 2021 at 6:31 am Hi, I have a Sea Ray 400 sedan bridge with twin all-mechanical Cummins 6CTA-8.3M’s in it. They are running great, but as we know, analog helm gauges are only so accurate. My tachs, for example, read 50RPM low on the SB and 50RPM low on the Port. That’s not too big of a deal as I make sure to account for that while operating. But I’d love to see the actual tach readout on my chartplotter. My prior boat was a 320 Sundancer wit…
2 RepliesAugust 8, 2024 at 7:56 pm I used the actisense EMU-1, unfortunately you need one per engine, but it does what you said and supplies all the signals over the N2k bus.Ā Ā In the end this was cheaper for 2 displays at each helm.Ā It doesn’t support EGT however.Last Post by:
