April 8, 2024 at 1:01 pm I’ve read the other posts here on this topic with no luck. Every initial startup, the belt squeaks for 5-10min. Then no noises the rest of the day. I’ve  replaced belt, fresh water pump, raw water pump, tensioner, and alternator. I’ve noticed a lot more belt dust on that motor than the other and am at my wits end. Could the alternator be working too hard initially? It shouldn’t, as the batteries are always on the charger. I also could not find t…

January 17, 2024 at 5:45 pm Have two (2) 6BTA5.9M2 marine engines with dealer installed VDO 0- 250 deg. F two- wire electric analog helm gauges. I know these type gauges are not high accuracy, but these are way off. Heat gun reading the sender base (and reading the accessible coolant areas will show 178-184 degrees and the gauge reads 205 (same both engines). My factory wiring diagram for these engines (12-v) shows positive battery voltage to starter solenoid, circuit brea…

January 20, 2024 at 11:51 am I had a no start issue at anchor the other day, & I could not hear the lift pump. At the connector I only had 8.6 volts with key on 1.3V with key off. I can also hear a buzzing coming from the HPCR pump (which is not normally heard over the sound of the lift pump) it shuts down after approximately 60 seconds. Applying 12v to the lift pump did not make it run. So it was toast. I replaced it with a used onboard spare but powered it with a dire…

April 20, 2019 at 6:47 am I want to say what a fantastic forum. It is so refreshing to find this! I have a 2006 48 SeaRay Sundancer with twin cummins QSC 8.3 (ESN 46529161 and ESN 46529055). My Diesel view controller head is part number 4932604 and I have rev 5 Sims on both engines. All my Smart-Craft stuff (analog dashboard gauges, engine sync switch, etc. works just fine. However, my diesel view display is starting to fade and appears to be hading south as they seem…

March 18, 2019 at 1:05 am Hi, Recently have had cases of alarm, fault code of “CCM Multisensor Lever 1” when engaging Starboard drive. Engine still runs. No drive. Can cure it by stopping / starting the Stbd engine.Then engages fine. Happens sporadically, but getting more frequent. Cummins QSC with ZF 305 A Transmission. Any others with this problem, or who have cured it? Much appreciated. Thanks.

November 15, 2017 at 10:06 am This came up briefly in another discussion but I thought it made sense to make the topic it’s own thread. Does anyone know if, on the 480CE, the engine data (such fuel burn, loading, RPM, etc) is sent over J1939 bus as well as the J1708 bus? The “C8.3 Marine Electronic Control System Troubleshooting and Repair Manual” shows a pin-out for the 9-pin diagnostic connector that shows both J1708 and J1939 high and low conductors. B…

May 25, 2023 at 11:44 am Replaced existing panels with two customer provided Cummins panels in a Fleming 55′ with two Cummins 480 CE. The only thing changed was the panels, but for whatever reason, the data being sent to the panels glitches out…  It will come in for a bit, then disappear, then come in again, and disappear. Under Data-link Info, it’s saying that 50% of the messages are bad. Any idea what needs to be changed to get the engine data to dis…

September 28, 2020 at 6:34 am Good day, I have had problems with insite program running the cylinder cut out diagnosis. The program simply locks the test out without any spacifics as what was the cause. I had cummings up date the origional ECM which did not solve the problem. Recently Cummins replaced the ECM with a new unit and the cylinder cut out test remains locked out. Cummins seems to be at an impasse. Anyone ever have this problem ?

April 27, 2023 at 8:56 pm Which direction does the alternator tension adjuster bolt loosen? Is it left or right to loosen it? Or is there some other trick to loosen the alternator to get the belt off?I even used a 15″ breaker bar after spraying with PB Blaster penetrant. This is on a Back Cove 34 with a Cummings QSB 6.7.

April 25, 2023 at 11:29 am Good afternoon, I’m curious if I can still get my hand in these older QSM11 engine alarm light modules are still available?  I’m in the process of refurbishing an old Hatteras that has them but the old ones look like hell and would like them to be fresh and new.   I believe they are the old C style gauges.  Any help is appreciated.
