On the MV Dolmar in Norway and Denmark, part of my job was to get up early in the morning and start one of these. Unless we were under way, it was the only way to make electric power, and, by switching belts around, compressed air to start the 700hp main engine. Always remember those little things that look like cigarette filters with lipstick on them! The Dolmar reverted to her original name and became a fine sailing ship, the Picton Castle, which has sailed around the world I think 7 times now, waiting for a Covid break to start the next one.
Yes! If you heard that coming from a petrol engine you'd be pretty worried! It seems like it was worse too a few decades ago when quietness of an engine was so important, and probably one of the reasons Peugeot were pretty much alone making widely available diesel cars. Once everyone caught on to how economical they are it changed quite quickly, and every car maker except the real luxury ones made some diesel versions available.
The way i stop my engine..it´s also a Sabb G..is to put the throttle all way back..Then you stop the engine.I would not recommend you to stop it with the de-compression-handle.By the way it´s a great little engine..about 200 kg cast iron but it works! Always.i use an oil from Mobile..5w-50.it makes it easier to start.best regards Claus from Denmark.
hi Claus, I have a Sabb marine diesel engine type 2HG 16Hp of 1970. (Serial n. 2HG 70-3) Can anybody advise what sort of oil I should use. They say not to use anything with the word synthetic or not even multigrade. Many thanks
@fiegenfeut I think using the decompression to stop doesn't stop the fuel from being injected. And since that fuel on the last strokes isn't burned it remains in your cilinder. And it washes away lubricant. And probably also has an effect on your oil.
I have just bought a boat with this same engine. Can you tell me what the "pellets" are called and where I can get them. they feature about 40 secs into your video

That simply is not true. Synthetic may leak where dinosaur oil would not, but that is about all. If you really want to use a straight weight, look for tractor/farm oil. straight 40 weight is often what they used.
@@xenu-dark-tony If all is well setup, your throttle leaver should be able to go down to a full stop. Using the decompression lever will cause the last diesel injected to wash away the lubricating oil in the cylinder.
Diesel oil is that oil very thin but it will lubricate not affect your engine, even when stopping the engine another way the pump is mechanical so fuel will dstill enter the cylinder

No. It's actually the same as the old Fire Piston kids toy that makes fire by compression air in a tube and having cotton burst into flame. en.wikipedia.org/wiki/Fire_piston

There is a PDF manual online which tells you which oils you should use I have a 2JGR 30hp narrowboats-freyja-and-christina.blogspot.co.uk/2016/11/making-boat-fit-engine.html Leave a message on my blog if you can't find it. Chop
M Happy - The oil is sucked up the hole to the dipstick, with a large brass syringe. But now use all the cheap electric pumps that are available for such use, but you have certainly figured it out now.
@@xenu-dark-tony Hi ! The way to stop the engine is to wind the throttle fully down ,if everything is properly adjusted it should cut the fuel and stop the engine. The injection pump has a stop fuel position. If you decompress whilst the throttle is open ,you stop the engine firing, but the fuel injection pump keeps on spraying fuel into the cylinder, and as there is no compression and explosion ,the injected fuel accumulates and washes the oil film of the cylinder, potentially damaging it. The engine is still spinning and injecting fuel due to the inertia of the flywheel and will keep on doing so until the energy in the fly wheel runs out. When you stop it via the throttle the fuel feed is stopped ,hence the engine stops firing ,the flywheel inertia will try keep it rotating ,but is quickly stopped by the compression when the decompressor remains "closed". Use the decompressor only when hand cranking ,or if your battery is not fully charged and lacks the power to crank the engine with the decompressor closed. An open decompressor allows the engine to speed up easier and then load the engine by closing the decompressor. Hope this helps. Its the tiny details that determines the reliability and endurance of an engine ,anything that can be done to avoid unnecessary damage is always good. These are tough engines but they don't deserve abuse. Good luck and safe boating my friend.
No, the life boat engine was Sabb GA (95 mm cylinder bore) and Sabb GAG (100 mm cylinder bore), these engine are direct injection engine (with combustion camber in the piston) while the Sabb G is swirl chamber diesel engine who need ignition cigarett or glowplug (some Sabb G has glowplug and starter as extra equipment).
