second station oil pressure alarm
This topic has 3 replies, has 4 voices, and was last updated by
1 year ago February 12, 2023 at 6:58 pm I have a 2004, 6BTA5.9-M3 with a OEM primary station at the main helm and a OEM second station analog panel on the flybridge. Ā The second station is sending an “oil pressure” alarm while the mail station is silent. Ā Both stations are showing 50 psi on the gauge. Ā The second station can temporarily silenced but activates after about a minute. Ā The mail station remains silent. Ā How do I know which station to trust? Ā Both gauges give th…

Crankcase ventilation / fumes
This topic has 20 replies, has 6 voices, and was last updated by

December 19, 2017 at 3:05 pm Just purchased Albin with twin 6BTA5.9 270hp engines. Engines ran at 2600 -2650 rpm with normal temps and oil pressures. Oil is venting from starboard engine crankcase vent tube into bilge at normal oil levels (per “hand marked” dip stick). If I let oil go two quarts low (per dip stick), venting stops and oil level remains constant (over the last 10 hrs run time). I’m still getting a lot of fumes in salon (engines are mount…

Aftercooler cap bolt broke
This topic has 5 replies, has 5 voices, and was last updated by

April 6, 2020 at 7:50 am Reinstalled the bronze aftercooler caps after servicing the my QSB 6.7 480 aftercooler and using plenty of Alco Metalube. Per the user manual I used a a torque wrench set to 33 ft lbs. A number of the bolts kept turning and didn’t hit the spec’d torque value. I felt one of them pop. Luckily it was only partially broken and the entire bolt came out easily. The bolt was deformed and stretched. It immediately snapped in half in my…

5 RepliesApril 7, 2020 at 5:02 pm Those same bolts could be used in cast iron or steel, where the 33 ft-lb spec would be close to appropriate. I would check the calibration of the torque wrench. It sounds like a lot more torque may have been applied. I recently did the whole aftercooler thing on my QSB5.9. I used the spec in the Cummins manual (32 ft-lb) with no difficulty at all. I have done a bit of “wrenching” in my time, and this felt fairly tight, but not ridicu…Last Post by:

Repowering the Cummins 6BTA Air Pre-Heaters
This topic has 7 replies, has 4 voices, and was last updated by

February 1, 2020 at 5:57 pm After several years of electrical glitches related to the Cummins 6BTA pre-heaters, I removed the system (except the heater coils) and instead, installed Wolverine oil pan heaters. They work well in the summer but not so well during Seattle’s cold winters. I’ve always thought that there should be a simpler system of powering the coils during startup that would mitigate the smoke and solve any electrical issues. After searching the kn…

7 RepliesFebruary 5, 2020 at 3:55 pm Paul, Thanks for your input. I’m also thinking of running just one element as well as it’s hard to get an accurate answer regarding current draw. Can you tell me how your system performs – are you satisfied running one element – is it doing the job? BobLast Post by:

Air heater – how long to operate

November 26, 2019 at 9:56 pm Hi Tony, Iām bypassing the ECM on my 6BTA 270 and wiring it with a switch and a light. My question is when and for how long should the air heater be engaged? Seems like pre-heating for too long could draw down cold batteries

13 RepliesDecember 8, 2019 at 8:58 am After one of the contactors shorted out, I removed the ECM, all contactors, and wiring harness (that was fun). I could wire the heater grid in the JWAC, and control it with a switch, but I’ve not found the need for the heater. The boat is active from April to November in Rhode Island, and other than April and November, I’ve not had a problem with cold starts. I’m on a slip, plugged in, and the block immersion heater (Fleetgu…Last Post by:

October 29, 2019 at 6:48 am Has anyone changed or installed a Custom Riser as to eliminate the water sitting against the turbo on a 04 Sea Ray 390 Motoryacht? If not have you installed a new that has upgrades from factory? Does SB MAR sell these? Thanks guys

raw water out in vertical section of exhaust elbowge

October 24, 2019 at 2:58 pm Hello all, new to this forum and diesel marine engines as well. I have been reviewing some info from this site which seems to recommend dropping the raw water out into the exhaust only after it has dropped down past the elbow to muffler or other then out. I am looking at a boat with a 6BT 5.9 M 270HP (1999) cummins and they current configuration has the raw water discharge in the vertical riser in the elbow before it turns back down. The boat do…

6bta more power
This topic has 2 replies, has 3 voices, and was last updated by

October 6, 2019 at 8:05 pm Hi Tony and the team, I have a 6bta jwac engine rated at 270 hp with the Bosch pump. On the surface it seems as though the next hp increase in Cummins evolution came from going from jacket water to a raw water after-cooler. So the simple question is can you just swap out and re-plumb the aftercooler for more hp or does this just open up a can of worms? Paul

2 RepliesOctober 13, 2019 at 1:34 pm Just modifying the aftercooler will not hot rod the motor, the fuel map is key to doing that. The injector pump and injectors and possibly other items related to increased internal loading/heat may be involved. Donāt forget that the drivetrain and propeller may also need upgrading with a power increase. Cummins has already done all the homework on this, and they offer their motors in a variety of configurations so that you can get what you need…Last Post by:
