Boat engine goes out of control on first test run

[@HansenBoatworks]

Hey guys, after some careful consideration we decided to reupload this video. We weren’t satisfied with the render quality, could have explained the situation better, and made several small errors throughout. So despite all of the wonderful comments, and attention the video was getting, we felt it would be best to put up a more polished effort for the long term. We’re really quite sorry about this, and appreciate all the feedback we received. Thanks!

I had a Sabb 8HP in a boat many years ago. It was raw water cooled so waterways were bunged up with rust. Replaced the exhaust manifold with new. Cylinder head was cracked between the valve seats. Had it welded with gas, reground the valve seats and it worked beautifully for a few years. Just like a sewing machine on tickover!! Eventually crack reopened and had to squirt a lot of oil into it with the special Sabb bottle to get it going.

[@myself248]

Friend had a turbodiesel where the turbocharger oil seal started leaking engine oil into the intake, and it promptly ran away, burning its own oil. There wasn't a quick way to block the intake, and the flywheel's potential-disintegration-plane intersected with the driver's cab, so the driver did the smart thing and GTFO. It ran well above redline for several minutes, filling the building with smoke until it burned enough oil for the oil pump to suck air. Evidently there was enough oil left in the bearings and journals that the thing somehow avoided seizing up as it revved down from the stratosphere. By this time everyone in the area had turned out to watch, and once the danger had passed, they set about opening all the windows to air the place out. They fixed the oil seal issue, replumbed the intake so it was easy to choke it out in case it happened again, and started it back up. Reportedly the engine was completely unbothered by the ordeal and was still running without complaint years later when my friend left the company. As a result of hearing this story, I've never let myself get near a diesel engine without a plan to block the intake!

[@air-drive]

This makes me think of my little brother, he was about 6 years old and he was on the tractor with one of out workers. The worker stopped at a gate and he got off and opened the gate but as he walked back my little brother had by magic put the tractor into gear and the throttle next to the steering column was pushed up to about idle, so when the tractor went into gear it started running forward. I will never forget the excitement in his face as he yelled to me, "look at me, look at me" And for a second I thought but there is something wrong with this picture, a 6 year old in charge of a 5 ton tractor that is moving forward and will only stop if it runs into something VERY solid. By now the farm worker was running like hell to catch up with the tractor so he can stop this monstrosity that is destroying everything in its way, and to make matters worse is that every single time the farmworker fell flat on his face my little brother was gasping for air as he laughed. So there the tractor went with this guy chasing after it, just like a Laurel & Hardy movie. By now, there were pigs running around and all of the milking cows were standing by the fence josteling for the best viewing spot (Cows are very inquisitive by nature) and the old barn (almost 120 years old) were next to get some of the demolition work done to it. But to every body's amazement he leaned forward and pulled the gear lever back into nuetral and the steel giant gave a huff and a puff as it came to a stop right onto of an anthill. Now that is what I see when that engine turned from a hit and miss engine to a roaring beast, best thing to do is grab your lunch box and get the hell out of there, she will stop as soon as the juice runs out but don't forget to anchor that baby to a huge metal spike in the ground before she gets to the Pigs or even worse, the Cows who will think it is Christmas when they see this engine jumping around and dry every single drop of milk out of there udders at least until Friday.

Reminds me of a story a friend told me about his older brother that had joined the Navy. Shortly after rebuilding a diesel engine, he was showing some superiors it running and the same runaway happened. Cutting the fuel wasn't working so he ripped off his t-shirt and jammed that into the air intake to stop it. Their father was the head machinist at a local boatyard. Loved heading over to that shop which was right down the street from where I grew up.

[@patcummins6036]

To @. May have been scavenging it’s own sump oil?

[@87mini]

That's what he was trying to do during the event but was unsuccessful due to leaking head gasket allowing air by during intake, like a reed valve on a two stroke. That was the main cause of the runaway. The mechanical diesel has a very simple principle, but the critical controls are oxygen and fuel! Diesel can go into runaway at propane or natural gas leak due to no user control of fuel, and go into the same by the operator's loss of control of the air - much rarer! This is an excellent lesson for that! Well done!!! The crank seal and governor plate gasket also contributed, evidently? Or perhaps were blown by the excessive pressure during the runaway.

I've seen quite a few people try to stop a diesel runaway by cutting the air intake and it's remarkably difficult, partly because a proepr runaway involves it taking fuel and air from places that it's not supposed get them from. A decompression valve is probably the best option because that's the only thing that you actually have full control over.

Anyone who has had a diesel start running away knows how dangerous they can be. Heavy parts spinning way above there normal speed is a recipe for disaster. Had an excavator that started to run and only stuffing a coat in the intake stopped it. Not easy to get to, and lots of noise of things getting ready to go wrong. Nice teardown and showing what needed to be fixed.

[@ben_doom1958]

In Germany we're using a "Notfall-17er" for such issues. Simply a wrench which fits the nut on the high pressure fuel line to the injector to loosen it in case there is a fuel pump driven runaway. On most engines the correct size for that thing is metric 17. If the fuel line is loose, the fuel will leak out and not enter the injector, stopping the engine.

[@ichbinwiederda100]

this is not realy a perfect solution because it can also be a faulty vlave shaft or other sealings like on Turbo engines. withch lets the engine run on its own lub oil.

[@donlunn792]

@@ichbinwiederda100what happens when it is running on its own oil? Or if it has slowed and gives a cough and runs backwards?

[@ichbinwiederda100]

@@donlunn792 The Problem is that the oil can also serve as fuel. So it keeps running away even if you shut off the fuel supply. The best solution is to block the air intake. Usually Diesel engines of this kind aren't able to run backwards without a special camshaft and the right oil pump for reverse, it will destroy the engine kinda fast if you let the engine do it.

Ahh...what a beauty. :) It's nearly indestructible and doesn't even have an oil pump. It has small shovels that splash the oil over everything. Btw.. for those who wonder... It's a SABB, not a SAAB. SABB was a Norwegian manufacturer of small marine diesel engines. In 2006 Sabb Motor AS was bought by Frydenbø Industri and renamed Frydenbø Sabb Motor AS. They also had a little encounter with Mitsubishi at a point in time. A lovely boat engine. We had a SABB in our boat but it was changed for a Yanmar diesel. It's a little more "complicated" than a SABB but equally tough and maintenance-friendly. We've been out sailing today...sunshine and 21 C. I love the summer is on its way. 😎🛥

[@BruceBoschek]

Very nice engine, running very well. Thanks for the video. I learned 60 years ago that if you don't have something with which you can block the air intake you had better not start a diesel engine for the first time. Using cloth of any kind for the purpose is inviting more catastrophe.

[@Jonathan.D]

The last time I saw one of these was in Vietnam when we hired a boat to take us fishing. It was a small traditional sanpan style boat. I almost fell over laughing when the owner grabbed the crank handle and started cranking. I said, "Is this a boat or a model T?" The throttle was controlled with 100lb fishing line run through a hole. He used a simple hand tiller for navigation. The exhaust left much to desired as it was a dry exhaust which was very loud. It was made of a few lengths of pipe that were run out the side and aimed down towards the water. I was impressed with the solid wood design of the vessel. My father was a shipwright who was one of the last in the area who knew how to work with wood. Over the years, I learned a thing or two about construction of wood boats. We didn't catch much, but we did enjoy the ride. After our hearing returned, we even enjoyed being able to carry on a conversation. 😄

[@suprlite]

I overfilled a sabb engine with engine-oil once by acident. It went absolutely bananas, like at least double the normal max rpm, and layed the harbour down with black smoke. It couldnt be stopped either, until it had used up the excess oil. But miraclously it survived :D Solid engines..

[@WindlePoones]

An engine run away can get pretty scary. I had it happen on another boat engine, A 1960's super charged Detroit diesel 4.71. I too was not prepared and couldn't shut down the air intake. I stopped the runaway by shutting off the fuel lines, before the sump oil ignited. I was lucky. The run away was caused by a small piece of debris getting past the fuel filters and locking the injector rack wide open. Afterwards i had to lay down on the floor of the boat for about a half hour. I thought I was having a heart attack, but it was just shear terror.

My brother got a P6 Fordson Major tractor and having bought it home and couldn’t wait to get it started. Unknown to him, the governor in the fuel pump had jammed wide open so that when started, it continued revving and increasing engine revs. Turning off the fuel had no effect, because overspending diesels start to burn sump oil as fuel. If left, the flywheel would have disintegrated and or the crankshaft broken too. To make matters worse, it was parked in the middle of the farm buildings. The engine note was rising from a roar to a scream and cherry red flames and gasses were coming from the exhaust. Fortunately, the primary air cleaner was off and I held a piece of scrap rubber over the inlet manifold and choked the engine by starving it of air. Whenever starting an engine that has not run for a while, check the governor and give some thought to plan B if this happens!

Marstal navigation school has a couple training boats, and one of them running this engine. My favourite by far. Pleasant cadence, lots of torque, and with a little knowledge, rock solid operation. They are probably still running it, and probably will be untill something major breaks. The other boat had a far more modern, small 4 cylinder diesel. What a hateful thing that was. 😂

Regarding annealing copper, the water bucket is not needed or there is no rush to dunk it. When you get coper to right temperature, it already has annealed and the rate of temperature change doesn't affect the end result. Sure it is nice to dunk it in water to get it cool for touching fast, but not needed for the process itself.

The diesel putt putted down the river as the water seeped in above the floorboards, then up to the engine mounts. There was no bank, nor docks on this branch. It was a race to the locks before I sank. The water was up to the flywheel splashing the cabin. I was sure I'd have to run her into the seawall. As we turned the bend there were the locks. And the lock tender saw my predicament and said would ya like a commercial bilge pump? Oh my. But the lil diesel kept firing all the way. What a piece of work. ;-)

Love these solid gasoil engines, stationary ones used in farm boreholes for raising water. Natural valve float gives some degree of runway protection, brave to slap hand over air intake.

Sandcast molds adds up quick with the man hours and complexity that that comes with the machining that comes with it. Cylinder mule engines were use as starters on larger 4 cylinder diesel cat engine, manually engaged to start the big engine. Either with the can's spray nozzle removed, injected directly into a common intake to ignite diesel within the large slow moving engines that produced massive torque. They sculpted the land to hold washing rains, trees stumps, shaped creeks slow water can be slowed down, moved to storage ponds for livestock, built roads, bolstered bridges for grain trucks, etc. A small company that built an engine for all was the air-cooled 4 cylinder Wisconsin engine. Designed with mount lugs, belt drives, external flywheels all standard or ordered by catalog by farmers or horse drawn implements. While many farmers has reached the point, they can't get information to repair their equipment, tractors or combined and argue with law markers for a "Right to Repair" bills. Want to go hungry? Want corporations to own the dirt, use their fertilizer, their blocks of diesel fuel 1 millions gallons per unit? Southwest Airlines did it! Engineers don't go home to stay after building a great tractor, Caterpillar, Combine or lawn mower with no oil service, airplane? No, they turn the lights on and create the new cheaper, lighter weight, transmission or power production plant. Woah! Produce electricity for trains, semi-tractors, grain truck, car or SUV? Will they pull a compact backhoe to the job site? Can't use coal, oil, hydroelectric power plant. Hell no to the thought of nuclear plants! Common sense tells you that the electric cars magically appear in all driveways Monday, job one is to charge the full before use. The entire country except Texas will go black. Why Texas, they have a separate grid unique to themselves! Texas is the 2nd populous state next to California. Get smart people! ASE Master Tech since 78, retired.

Sabb model G, great engine, had two of them. Hard to shut off the air on however if she runs away. I still have parts and a variable prop.

Thanks for sharing your experience with this unique engine. In the video, you mention not having a provision to block airflow into the engine intake. It is a good thing you didn't try to use your hand. I have heard about some pretty bad things that can happen if the airflow is blocked by a body part. Also, I have heard stories about diesel engines that had lub oil leak into the combustion chamber through a bad blower seal or cracked ring and overspeeding on that. Cutting off the fuel flow on a runaway works most of the time, but cutting airflow is the best.

[@platinumsky845]

Since runaway states often are getting air from places it's not supposed to, like the leaky head gasket in this motor, the best method sometimes isn't blocking air flow, it's providing decompression.

I had a runaway on a Peugeot 2.0 diesel van engine. Once I got my head around what was happening I was able to stop it by putting it in 2nd gear and feeding in the clutch whilst standing on the brakes and hoping the clutch didn't burn out.

I just jumped on a mates boat with some servicing gear and dropped the oil on an old Sabb single banger, threw a new belt on it. Lovely engines...... they love a bit of blowtorched hot air in the intake on a cold day cold start scenario.... greetings from New Zealand!

[@navigator100group2]

I had a Sabb 10 in a boat in 1973. CHECK the gearbox oil. The air intake travels down the starting handle across the gearbox, then up the push rod tube. Gear oil thrown into the air stream will cause the engine to run away. By the way, if it gets to 1800 RPM. Stand well back; the machine's next move is to part company with the flywheel; You will never find it. It will make its way into the next county😁

[@davidaitken4157]

Man you can have every thing that opens and shuts .... But have to to have the knowledge to go with it Nice job Guys 😊

[@peteb2]

That's just fantastic! I'm a little concerned with there being no exhaust manifold how that works out in a boat or does in run only when out in the open air?

[@The-Host]

What a super cool old motor. Man, it doesnt get simpler than that until you get to a 2 stroke.

[@michaelmullan9640]

My dad had a similar engine (1968 model GG) it was fun when we got the push rods on backways, and the engine sucked in through the exhaust and out through the intake. also ran away from us until we unbolted the fuel injector line! I loved that engine.

[@BurchellAtTheWharf]

This bad bouy of a single banger sabb wants to run like mad, so much potential Wakening up from it's long sleep with a vengeance

[@kevinwilson8350]

Love it. Can't wait to see more. Have fun & stay safe cheers Kev.

[@looneylonzo28]

that would be an awesome engine to put on a small rail cart and then put it around on the old abandon railways. I actually know where there is a motor not identical, but very much the same it is still running to this day in a field in north Louisiana. It is operating in oil pump, well pump. It even has one about 200 yards away from it pumping, but it’s much different that one has like a 10 foot stroke at the end of each stroke is a big huge relief of pressure. It’s an awesome sight to see maybe just because I’m a gearhead and I love engines without the internal combustion engine. We would still be living on dirt.

[@williamshelton9688]

Hi , where are you guys located ? I have a Sabb that I can’t get to run right …any help available ?

[@Animalignis]

The Sabb engines (Sabb Motor) where build in Bergen, Norway. They where much used in costal fishing boats and in lifeboats globally. The engines are still highly regarded. I still remember the distinct vibration and sound from my granddads single cylinder 5-8 hp. It never failed. The lifeboat engines have an easy life and can be pristine even after decades in service.

[@skaraborgcraft]

Many , many still in use today in Sweden/Norway/Denmark. I prefer the later Bukh 10 at almost half the weight.
