Alarm question got 3208
This topic has 5 replies, has 4 voices, and was last updated by
4 years ago February 4, 2020 at 4:43 am I know this is a Cummins forum but was wondering if seaboard sells high coolant temp alarm and low oil pressure alarms that would work on my 3208? Thank you, Tom.
5 RepliesFebruary 6, 2020 at 1:49 am Its been a while.. But the coolant alarm should go to the low oil pressure switch( round cylinder about a inch long). It should be at the rear of the V on the head.Last Post by:

CAT 3126 MUI. Leaking injector?
This topic has 2 replies, has 2 voices, and was last updated by
4 years ago January 18, 2020 at 9:25 pm I started the motors after having sat about 6 weeks and I noticed a small splattering of what I think was diesel fuel rainbow drops in the water from starboard exhaust. They cleared up/stopped after about 3 minutes at dock idle. Next day I started the motor again and no rainbow splatters. No unusual smoke at cruise and both motors seems to be running fine. I did notice this past summer that only after several hours or trolling Iād get a bit m…

4 years ago December 25, 2019 at 10:51 am I’m replacing the Tachometers in my Cruisers Yachts 460 Express with VDO Viewline Tachs. I think the flywheel on the engines have 127 teeth. I need to set the pulses per revolution on the tachs. Is it 127? instructions are attached. Thank you

3 RepliesDecember 9, 2019 at 1:52 pm Would not be part of the OEM setup for heat exchanger cooling. Looks like you’ll need to get the heat-ex end cap setups, elbow raw water connector, and the raw water pump hose and nipple.Last Post by:

Raw water pump failed on 6bta Cummins mixed water with oill

4 years ago December 8, 2019 at 11:32 am I have drained and refilled oil and changed the pump, what a nitemare! Ii have moisture in the engine, steam coming out of valve covers. Any ideas on how to remove this moisture. Oil is no longer milky. Thanks in advance.
1 ReplyDecember 8, 2019 at 12:27 pm You are not really saying what happened.. Fill us in.. How much water was in the engine? Usually it take more the one oil change and then if you do not get the oil hot ( like up to 200F+), it’s hard to evaporate the left over moisture I’m thinking here————-If the water came in from the pump, then that means the bearings were totally shot and the gear was moving around in there–Gear damage is very likel…Last Post by:

yanmar 440 exhaust
This topic has 1 reply, has 2 voices, and was last updated by

December 2, 2019 at 4:31 am I have a yanmar 440 vdrive set up . it has stainless exhaust and the mixing is right next to the turbo , can I get this welded closed as its new and move the mixing to the other end of the run and wrap the stainless exhaust thanks for your help
1 ReplyDecember 2, 2019 at 7:47 pm I believe we need better pictures to give you a real answer. It can definitely be cut up and refabricated but you need to have the room to accommodate the mixing on the downward side. It may or may not be cost effective compared to building a new one. All depends.Last Post by:

Volvo D4 which test do you trust
This topic has 17 replies, has 2 voices, and was last updated by
4 years ago October 17, 2019 at 8:12 pm Fighting lack of power loss of rpms . Computer scan shows weak compression/ power output on cyl #1 & 4, and full output on 2&3. Mechanical compression test shows cyl 1&2 equal and cyl 3&4 equal . However 1&2 are 50 lbs less than 3&4. Which test do you trust ? If computer scan is reading wrong would that mean the computer/ecm is bad ? Thanks
17 RepliesNovember 16, 2019 at 11:17 am So far so good, but that looks like an intake valve? —————–Is that #4, the most likely one to have seen water unless this was a v-drive application , then #1..Exhaust valves are the ones that will show what is going on as to water.Last Post by:

October 8, 2019 at 6:30 pm I just did injectors on a 825hp series 60 for a friend of mine. Barred engine over and set injector heights accordingly (81mm) after installing unit injectors. Note motor was guaranteed to be in correct position at this time as valves were exactly where i set them during tune up in april. In addition, each injector had to come down. I attributed this to new springs. Boat had run over 100hrs since tune up flawlessly. Upon testing boat toda…

Exhaust Design headaches
This topic has 2 replies, has 2 voices, and was last updated by
4 years ago August 10, 2019 at 4:43 pm Hi I have a 28 Foot trailered aluminium mono with a volvo 230Hp KAD43 and sterndrive. Motor is currently being rebuilt due to the common exhaust too low issue. Because there is a flush deck cockpit I have some challenges in redesigning the exhaust. To make it even harder I have been trying to design it so the exhaust still exits out the outdrive (less fume and quiet) My manual states the exhaust pressure spec as 10ā30 kPa (1.4-4.3 psi) (100…
2 RepliesAugust 10, 2019 at 8:35 pm Just ask yourself one question if you go with a shower design.. When one of internal welds or inner pipes rots thru ( it will as they all do), where will the saltwater end up…. The “orange run”, if done right, is the only real solution. Up and over the top , water injected on the downward run. TonyLast Post by:

MAN DO836LE401 450 hp rated @ 2600 rpm

4 years ago July 3, 2019 at 11:02 am Hello, BillD from the Cummins side of the forum. Well, owned a pair of Volvo 41P 200 hp for a couple of years. OK, my question/s? I’ve been perusing some mid 2004-2008 boats and came across some diesels I’ve never seen, studied, nothing. The MAN 450 hp @ 2600 rpm. I think the engine came out in 2002 ? No longer produced. Anyone have any experience with this particular model MAN ? Thanks,

1 ReplyMay 7, 2019 at 4:22 am All you have to do is read this and understand your particular situation..

exhaust temp
This topic has 2 replies, has 2 voices, and was last updated by
5 years ago April 9, 2019 at 6:02 pm I just installed your exhaust temp guage on the yanmar 4jh3-hte. I’m reading near 80 degrees celsius on the coolant temp and 350 degrees Fahrenheit when warmed up. engine runs fine but some very light white smoke at idle and throughout rpm. also tiny bit of sheen in the water. Is 350 too low? If so how do i increase exhaust temp? note: could it be location of probe? see picture.

Engine choice?
This topic has 1 reply, has 2 voices, and was last updated by
5 years ago March 19, 2019 at 9:41 am Looking at two basically identical boats (OA 52 sedan…’05 & ’07)…one (’05) is powered with twin Yanmar CXM 500hp and the other (’07) with Yanmar 480hp 6ly…hours on both are roughly 1,200. Found a lot of info on Yanmar 6ly 480 but not much on the CXM… Any insight on either would be appreciated….obviously full engine survey by Yanmar guy if it gets to the deal stage. Thanks Bryan

5 years ago March 23, 2019 at 10:05 am Absolutely stoked to have signed up here. I apologize for the Yanmar question, but I know at one point Tony offered a fuel cooler elimination for the 6lp. My General Marine has an above deck fuel tank on the stern so I was thinking about eliminating my fuel cooler. Does anyone know who sells a kit or would SBMAR be willing to make one up for me?

Qsb 5.9 aftercooler test pressure
This topic has 7 replies, has 3 voices, and was last updated by
5 years ago March 24, 2019 at 6:32 am I have removed my intercoolers for the first time and found one to be totally unserviceable and I’m hoping the second will pass the leak test. What is is pressure used on the core and do I need to test the fully assembled unit too? I believe the replacement unit has been modified to the Seaboard standards already and doesn’t need to be greased
7 RepliesMarch 26, 2019 at 6:06 am 20 PSI is fine………Pits inside the cooler housing do not matter–Only the flat sealing surface ( on each end) after block sanding…….. Our coolers come pre-greased and are good for 2 years or so before you need to service it again if in seawater.. If you fresh water flush diligently when at the dock, you can easily double the service time interval. TonyLast Post by:

9 RepliesMarch 18, 2019 at 9:27 am You might think about plumbing a coolant loop through a new hot water heater. This will get you really HOT water any time you are running that main engine, and it stays hot for a day or two after you shut it off. Virtually all marine water heaters (Raritan, Seaward, IsoTemp) are available with the coolant loop provision, and I can tell you from experience with our Hatteras 36 that it works very well indeed. Also, if you run the engine (and, by e…Last Post by:
