Gear oil fuel oil cooler Cumms #4939924
This topic has 3 replies, has 2 voices, and was last updated by
1 year ago July 26, 2022 at 10:45 am Hello all, I am having difficulty locating this part or an aftermarket part anywhere in the USA for my marine Cummins QSE 600. Anybody with a good source? I am all put together from an ordeal and this is the last part of the puzzle. Mine cannot be cleaned/ repaired. Thank you!
3 RepliesJuly 28, 2022 at 5:51 pm Lenco will most likely do you very right.. That fact that they took the job is very good for you.. My guess is now, they have a pattern for the future which is good for all as the Cummins supply change is now working very well these days. TonyLast Post by:

370 6BTA won’t rev beyond 2450 RPM
This topic has 11 replies, has 3 voices, and was last updated by
1 year ago July 5, 2022 at 10:33 am I have a 2003 Meridian 411 with 370 Cummins engines. I normally run at about 2300 rpms which puts the boat just up on plane. I was checking out a leak in my dripless and tried to run up to WOT a couple of weeks ago and found that my port engine would not rev past 2450. This engine is a Cummins factory rebuild that I suspect has about 1000 hours on it. The previous owner did not log the hours when changed. The fuel filters are new. I took the ai…

Gear temp discrepancy
This topic has 4 replies, has 4 voices, and was last updated by
1 year ago July 25, 2022 at 2:21 am Morning USA This discrepancy seems large to me – other than ongoing issue with IMT fault (which I am assuming definitely isnt related as this is Zeus pod area) – should I do anything like replace transmission coolers on the pods? My guess is they havent been – 10 yo boat with 200 hours – Whilst the temps are not outside SBMAR tips and hints Im not overly comfortable with such a difference

September 27, 2019 at 4:55 am I have a 2005 Searay 390 MY with a pair of 480 CEs, 370 hrs. The Smartcraft display is in good condition however it dosent display boost or exhaust temp readings. I seem to recall reading that there are sensors for these on board the engines but readings can not be displayed on the Smartcrap. I think I recall reading that they can be read with the right diagnostic software. My question is this… can I install guages that will display these …
7 RepliesJuly 27, 2022 at 7:01 am Matt I never got any gateway. That is beyond my ability. I only get engine data on my failing Smartcrap System View. For Boost and X temp I bought Seaboards Turbocator package. Easy to install and independent from other systems. I wish I could display other data on my Ray displays. I understand I could do new harnesses and buy Seabord data displays but that’s a tough job and the displays are too small. 480 CEs are fine, but language challenged.…Last Post by:

July 22, 2022 at 12:12 pm I need to replace the flexible hose from the turbo. I don’t see any way to get to the oil connection without taking expansion tank and other components off. Of course it’s on the starboard side. Any suggestions? Thank you

False High Temp Alarm on Cummins 6B Recon

1 year ago
June 16, 2022 at 2:55 pm I have a pair of Cummins 6b Recon engines (DOM 09/28/15) on a 42′ Hershine that I purchased about a year ago. The engines have about 100 hrs on them. A problem has developed where I am getting a High Temp Alarm on the port engine when the running temp shows about 175F. I have confirmed the gage temp and the engine temp with an IR gun and find them to consistently read within 5F degrees of each other, so I am fairly confident this is not …
6 RepliesJuly 23, 2022 at 7:14 pm I purchased the SBMarine high temp alarm switch, adapter and buzzer for each engine, installed and bypassed the PCB, but disconnected the high temp lights on factory panel and wired them into my new high temp alarm set up. They work perfectly. When I put a jumper on each high temp switch, the new alarm sounds and the factory high temp light goes off just as it should.

Cummins 6bta 270hp transmission noise
This topic has 4 replies, has 2 voices, and was last updated by
1 year ago July 20, 2022 at 5:47 pm I’m under contract on a boat with a Cummins 270 hp motor. I’m unfamiliar with diesel engines and I’m hearing a noise when the boat’s in gear that’s concerning me. this video is shot with the boat running around 1000 RPM. The noise is reduced at higher speeds but maybe only because the engine noise overpowers it. You don’t hear the noise in neutral so that’s why I figure it’s the transmission. It’s a reversing gear transmission. Maybe it’s a…
4 RepliesJuly 22, 2022 at 9:38 am The deck, hatch, insulation, bilge and close coupled reversing gearbox all say Albin 28TE. Very hard to diagnose sound via a recording. The last ZF63IV that I heard that sounded like a knocking noise that increased with rpm had a bad bearing and needed to be pulled. I’d say do your best to get a qualified ZF guy out there.Last Post by:

1 year ago July 15, 2022 at 6:58 pm I have twin 5.9 370B with the SMX style double fuel filter set up. FS 19513’s and the FS 1000’s. Both filters have vacuum gauges attached to them. On the Starboard side I see 3-4” on the 19513 but on the 1000 it will show around 8” just after a short run. I have changed both filters out and cut them open.

480ce fuel burn difference between engines

June 20, 2022 at 8:17 pm 2005 Sea Ray 420. Getting a fuel burn of around 14.5 gallons at 2200 on one side and 13.7 on the other. I also noticed the side with the higher burn rate runs a coolant temp of 165 vs the other side at 158. What can I check to see if one is too much or one is not burning enough fuel. Motors are 480ce. Just purchased the boat so upon testing this is what I found. Thanks.
