The sound of those takes me back to my teen years when out family had a Silverton with 2 Cummins. Great vid!

Great running Cummins! Sounds great!

I'm 22 now but diesels still sound just like when i was a kid....nice song for my ears:)

you have to be proud of your dad !! - that some cool boat and engines.

Ahh okay. I've only ever heard of cummins in trucks and transport trucks. Thanks for the help!

I can say just 3 words: BIG, loud, powerful. :) Nice work!

I plan to repower my Sea Ray 340 Sundancer with Diesel when the time comes. Thanks for the vid. Was very interesting.

Always nice to hear the great 12 valve 5.9L straight block million mile cummins engine. there no another to compare.!

Cranking is just good , i love it . Rebuild engines always takes forever to start the first times

Youand your father did quite well my friend. a job well done. 5 stars

love the sound of a Cummins👌

I like what u did. I have several marine cummins layin in my garage. After watchin your vid I got fired up and emptied the two car shop so I could get to my motors. I wil fire them up and respond in two weeks after p7100 pumps are cleaned and bench tested.

Very nice sound on that Cummins :-)

damn that sounded nice when u put the camera by the exhaust pipe, great job

sounds and looks really nice!

@GinoJerry86 This is a boat engine. Marine engines use water to cool the exhaust gasses. Raw water is taken from the outside and pumped directly to an exhaust elbow and mixed with it to cool and to dampen the noise. That is why you see the water in the exhaust.

thats such an amazing sound...!

The water in the exhaust is the waste from a heat exchanger. The water is sucked from under the boat and taken to a heat exchanger which is like the radiator on your car but instead of air rushing through it to cool the antifreeze, it uses water. There is a closed cooling system filled with antifreeze on the engine like in a car and it runs through the heat exchanger and transfers the engine heat to the seawater that runs through the other side of the exchanger.

Nice! I see a good number if Bertrams here on Lake Michigan. Their quality built.

Thanks. You should hear it in person.

I love that sound, I've been on a transportship that has a Cummins V12 (size was about 2 times bigger than this engine) but that sound was really great! also electric started:)

that is a nice set up for a 33'

@urbex2007 It doesn't have huge holes in it- it's a cotton gauze filter. It's designed for this type of application and as long as the media isn't damaged it can be cleaned and reused indefinitely.

man I love the sound of deisel in the morning. I cant wait to work on highway and off road deisels.

Sounds super

That's a beaut rebuild. No surprise if the first start is a bit cranky. I want a bigger diesel now, I miss our Cat D8 with donkey engine starter. Sounds great!

from the sea water pump is their any were that i could hook up a wash down hose before the water enter the engine to cool it without affecting the cooling of the engine

Nice engine great sound. Took a bit to get her going but it sound like she will purr for a very long time.

I know nothing about marine engines but it's impressing, there's a lot of water :S

@scott93257 Thank you for the compliments. I appreciate all technology.

even if your a seasoned engine builder you still do a lil happy dance when she fires

Where can I find a heavy duty starter like that?

because on marine engines the header is cooled by a water jacket, otherwise it would glow orange. So typically the seawater runs through a heat exchanger, and then passes through an exhaust manifold, which is called a riser, then is dumped in to the same exhaust pipe where it return to the ocean.

Its a 12v Cummins Marine, so its water cooled. Hence the water hose connected to it.

I am a diesel fitter, used to work on the big leyland and gardner engines, after rebuild it was quite normal to sit there with the throttles wide open until you got the fuel up then they would pick up one cylinder at a time etc often a couple of mins tho even with that.

Can't say I like the Martha Stewart white paint job you got going on there.

its a 5.9 5.7 cummins c series i think a great engine ive had the pleasure of buildin a few simple and bullet proof as with any mechanical engines

FYI - 1) Diesel engine (high) main bearing pressures on starting are unaffected by installation, and only increase by less than a singular factor under full load. 2) The correct start procedure for a new (or rebuilt) h.s. diesel engine is to have first greased the mains etc. with pre-lube (maybe you did) and then ENSURE the engine starts immediately and evenly by doing a fully pressurised (forced) bleed. Piece of cake with the Bosch style pump. Larger engines pressure pre-lube.

Both engines were installed last year and have been working flawlessly. Thank you for your interesting comments.

we rebuilt the thame engine 6BT5.9-n best regards from germany

that starter took a beating

cummins 6bt...best engine ever freakin built

The startup rig was made from an engine shipping pallet that I added wood blocks to , to lag screw the mounds to. Not really sturdy but with no real load on the engine it worked OK. That's one of the reasons I didn't open the throttle to bleed it, I was a little afraid it would rev quickly and come loose

@jac70j No glow plugs in a 6BT. It has a grid heater.

@RocketRodder Yes, normally both engines are used at the same time.

You have to prime the fuel system and injectors if they are dry (ran out of fuel, never been filled with fuel, or opened to air), all other times it's just turn key and go.

Miss building these, although i never built a 6bt for marine app, Used to build 6btaa with side mount turbo. In addition to the colour questions white was marnie, red or tan for automotive and also they did green reconditioned engines.

did that engine just piss it shelf ? lol .great vid ,love diesels power !

Glad you didn't doctor the video, and then us gear heads can follow the progression and cycle timing. The others are right, there ought to be a way to bled out the air from the fuel lines before running the starter so long. Had a Dodge Dakota 5.2L v8, obviously Chrysler. Changed the fuel filter routinely running the vehicle from age 12-16, the last 80K of the 220K life - gasoline engine. There was a way to depressurize the fuel rails. If I recall correctly, it was removing the starter relay. Then cycling the ignition which bleed the fuel out of the rails/line and I wouldn't get soak with gas when removing the filter. I think there's a pre-start phase where the fuel rail / lines are pressurized before turning over all those cylinders to otherwise the injectors are shooting blanks blasts of air rather than diesel fuel. So, otherwise the A/F ratio is sky high and you don't have sufficient fuel for combustion. Which in a diesel engine, it's an explosion, rather than a rapid burn in the gasoline (Otto cycle) engine. Within the gasoline engine there is a flame front that propagates from a point of ignition to the furthest extent the fuel resides. Imagine being in a coal mine where the air is saturated with coal dust because the ventilation system failed or is undersized. At a certain coal to air ratio the density is potent enough for a point of ignition, from flipping a defective switch. Then watch out. In your case, you're cooling cylinders that aren't firing. In your initial 179 seconds, you're running a large air compressor than leaks.

this is the engine that the dennis dart pointer has

Marine engines draw water (for cooling) from the body of water they are in (in this case, a hose). Once it is circulated, it gets dumped out of separate channels along the exhaust.

the 12v's use a throttle control valve, the 24v's use an , and its electrical, the newer QSB's are also electronic, and don't have a "throttle", but that model year if i remember was throttle cable driven.

I would love to, but i'm over 4000 miles away :D I have to say, i am a cummins lover. And even if they rev high, those are very reliable engines (for what i have read^^)

All inboards typically are freshwater cooled, using exchangers to cool off the coolant, then the seawater is run through the headers, and then through the riser where its then dumped into the exhaust pipe, this is the only way to drop the pyro temps, ANY mechanic who works on marine engines knows that, the exception are stacked ships, where the seawater isn't mixed, but rater sent overboard, when the exhaust pyro temps drops to a safe level.

Thanks, Yes.

Thanks for the comment! History is the kinematic mechanism of existing structures. Our engines are smaller but more powerful and more efficient. Live is life, and develop internal combustion engines. Also change and fuel - would rather use hydrogen. The future is coming with us! Kolev Motors Varna / Bulgaria

Starts like a Cummins !

Great video, nice to see them come alive like that, hows the VT 555 compare to the 6?

@crazydiesellover yes, its got a marine cooling package on it.

that is amazing

in or out of ram. love that puuurrrr

@Superiorpakfan It's a Cummins 6BT, better known as a B series. Where I work, we have several small buses with this engine.

It's a marine engine. The cooling water, after going through the heat exchanger etc. , exits with the exhaust , mixes downstream. of the turbo, in the elbow.

275hp RV injectors reduced the ETC engine's 0-60 time from 17 sec. to 14.5 sec. Available from TST. Available from Cummins - BOSCH part# is 0 432 193 635, cost is $80 each plus shipping, instructions are not included. Installation time: aproximately 1 to 4 hrs. depending on experience (it's not difficul

@ilovegoatsecks It's supposed to since it's a marine engine. Water is run through the exhaust to keep them cool.

No, they actually need to be painted in layers of different colors with varying protection values. Red has to go on first, followed by white and then finally all the paint must be stripped off and left to nice shiny bare metal.

I'm the father in question so maybe I can answer . The engines were marine engines , both had been overheated and were cores. They needed many new parts,like turbos , manifolds, wiring harnesses, most internals etc. ,not to mention the machine work. It was fun but didn't save much money really.

some knows if there is a video about PT Cummins Injection Sistem, or where I can find some information about it?

Appreciate the response.. but it's kind of hard to believe it would take that long for the fuel to get to the injectors. Anyways, thank you.

We checked it several times and it remained cool. The rest periods are also edited out of the video.

Hi, Thanks for the video. Is that a 6BTA? I was that engine in a 33' Deltastar. I have two problems I could use some help with. The batteries will not start charging till I rev it up to 2000. The alternator has been checked... Also it is very hard to start, I just fixed the a wiring problem which didn't help but the engine isn't firing up for about 10-15 secs. Any ideas or tips? Thanks

You wouldnt have vids of the Bertram would you? I love to see it! Thanks.

It is a Marine Diesel. Water is used to cool the exhaust manifolds.

@ GinoJerry86 estemotor es posible que sea utili8sado para una planta de energia ...el diseño del turbo de este motor es de refrigerasion por agua de ahi dela carcasa de escape del turbo debe ir una mangera asia un radiador mas grande que evite el recalentamiento.

in the US we tend to use a wet exhaust system, because it works very well, it is the only way to cool down exhaust, especially coming from diesel engines, where pyro temps are usually 500 degrees hotter then in a gasser. Cummins Mercruiser, like Crusader use freshwater cooling, with a heat exchanger, like i said earlier, maybe i didn't make my self clear enough?? I am a diesel mechanic, i work on diesels, and ive been around enough CAT and QSB's, Detroit's to draw circles on most people.

@rthom86 aye, tehn after that, the engines compression takes over the ignition duties. these engines are gems my friend, never thought id like engines in whie. btu you know what. tehse thigns look, AND RUN great

This is a marine engine so yes it uses a heat exchanger and then raw water to cool the system.

Nothing beats a hummin' Cummins! Love that sound. What are the horsepower and torque ratings of this particular power plant?

im pretty sure it was built for marine applications and those have to be water cooled through the exhaust to keep it from overheating... yet i could be wrong... can anyone confirm this?

Why wasn't it cranking at the beginning?

@GinoJerry86 it is a engine for a boat, its cooled with water

@HeresJamesPrice dont know where you got your information from but you are incorrect sir. the water in the exhaust is because the engine is cooled using raw water (ocean or sea water) from a pickup in th boat and it goes out the exahust to cool the exhaust and the exaust sometimes goes into the ocean water to disperse.

hi need to buy one,how can i get in contact

how much toque and hp does she put out? how many litters is she? really interested in knowing.

for a while i thought it wasnt going to start

Very nice .. would love to see the boats they where in stalled in ... and do you use a smaller diesel engine for a generator?

why is all tht water coming out the tail pipe??

Ben folds five, I think the song is "Brick".

the sound of good old american diesel power. jizzz in my pants!

@12VDISLMT White for marine application.

Sweet.

ok so then it doesn't acculy go threw the cylinders just near the exit then right

@GinoJerry86, the reason water is coming out the exhaust is because its a marine engine, they pull water from the lake, river, or ocean and after the water passes through the block to cool it, it exits out the exhaust back into the water. i dont know were this other guy got his info, either he has no idea what he is talking about or he is screwing with you.

Very nice. Whats this engine's governed speed just out of interest?

i know its usual for water to come out the exhaust of a marine engine, but since this one is drydocked, wheres the water coming from?

What type of cummins is it? Just at the near end @ 6:24 sounds like ISL

I love all the comments regarding the engine leaking, its a marine engine, its supposed to have water exiting from the exhaust you dummies.

How much approx. does one of these power units weigh?

I don't see how Cummins can be the worst boat engines.? They are one of the most popular marine engines used. Thats a fact. If they were that bad that wouldn't be the case. The Cummins B series engines have an incredible record of reliability and durability. I agree on the Cats.

Porque sale agua por el escape ???
