Manouvering with a Wichmann (Rubb) 40 hp semi-diesel

[galax650]

fantastic sound!!! i would love to see those old hot bulbs in use here in finland more often.

they are kind of rare theesedays

i own a 5meter wooden fishinboat or do you call it **snipa** with a bernard 6hp engine. it sounds nice and it's a low rpm engine too, but it's nothing compared to this!

btw check my boat videos

My experience has been that a properly matched muffler does NOT hurt the performance of a diesel engine. I would think you would be a lot more popular around the harbor with a proper muffler. Also, it would seem to be less tiring to the crew while underway.

Or, are some boaters like some truckers, and just like to be obnoxious?

[SveinHaDD]

@jgmagoo1 Please note that this is a two-stroke semi-diesel. Any restrictions in the exhaust will limit the amount of air entering the engine and cause loss of power...

The engine have a kind of muffler but it is only an empty tank sized about 100 litres.

[jgmagoo1]

@SveinHaDD Not true. I am an engineer and have been involved in several lawsuits pertaining to noise laws and diesel engines. It has been proven that noise levels of all types of diesel engines, both 2-stroke and 4-storke can be significantly reduced and still maintaining a ZERO increase in backpressure, It has also been demonstrated that some diesel operators just like noise!.

[SveinHaDD]

@jgmagoo1 You are welcome in Norway with your lawyer friends. Here is there absolutely NO semidiesels with different muffler than in this video.

It would be interesting to have seen a muffler that was efficient after for example 10 years of soot and oily exhaust... Putting a modern muffler on an engine built with 80-90 year old technology is considered rape.

[EngineEngineer]

@jgmagoo1 its not like any diesel you have worked with. it is a hotbulb engine and they will NOT work nearly as well with a silencer

[Arvid1940]

Folks, that is the real mac coy a Norwegian manouver in Sandviken of Bergen, this is the real thing, no BS

[Tjita1]

What does that crank do? I may add that I know nothing about boating, but every bit of technology is interesting in my eyes.

[SveinHaDD]

@Tjita1 The crank changes the propeller pitch to make the propeller push the boat forward, neutral or reverse. Please note that in this video, the governor was out of duty, the engine should be able to maintain a far more constant rpm

@royalbrainwave

I´ve had two own boats with hot bulb engines. I used them on a year around basis. Besides i have renovated/ rebuilt a handful of separate engines. Most of them had centrifugal governor, three of them were hit and miss engines. I helped countless others with "troubleshooting"on there engines, (and i occasionally still do..) Nowadays i am captain of a boat with modern, "computercontrolled" turbodiesels, but i miss the raw simplicity and function of the hotbulbs.

[foreverthewho]

er dette her i Granvin (fordi at dampbåten ligger der:) )

[SthealthRaider]

Could you make a vid on you docking that boat :)

[hristogh]

Hi is the best

[OFY17]

Far too much pitch, and a bit to low idle in all of these manovers! :( -Remember, these engines are supposed to "sing" not "cough" while working!!! / Skipper

[SveinHaDD]

@OFY17 FYI, the governor was totally out of duty in this video. We repaired it later the same day...

[royalbrainwave]

@OFY17 you're one of those book smart types probably who when asked to do some actual anything can't do it because you never did anything besides read about it.

[Ragoskargardskanal]

Very nice sound!!!!

[bebajoro77]

There's a beautiful boat and a guy who knows exactly how to handle her. Not to mention an remarkable engine - I can't see many "modern" 40hp engines performing like that

[andyunderground]

Hej!

Trevligt ljud !

Jag hade en Engelsk kutter som hette Dag-gry 1.

Den hade en 1cylindrig wichman.

Fartyget var byggd 1893 i Lowerstoft.

[BlakeMason2]

That pilot really knows how to work in tight quarters! Really neat view of a mini-harbor. Thanks for sharing. Flott Video!

[randknu]

Det ser ikkje ut til at skipperen e så stødig med manøvreringå.

[vesternor]

my uncle is fasinated with this video! he keeps playing it over and over again.

[tomterahedrob]

how big is this boat?Thats alot of boat for 40hp.Gorgeous harbor!

[SveinHaDD]

I'm not quite sure but I think it is slightly below 60 feet. These 40 hp engines can be compared to about 200 hp modern diesel engines.

[tomterahedrob]

thanks.I bet thats because of the lowspeed torque.Honest engine.

[coriolisi]

By the way, manouvering this beauty requires

a not common skill,

about the engine, well..lovely sound is not the right definition....

This is "musica paradisiaca"!!!

[Mitsugejl]

Nice indeed, guess you have tried this before :) I've seen a fisherman run his vessel straight into a pier once, he came into port after a fishingtrip and wanted to slow his vessel down by reversing, nothing special. He throttled down his engine and turned the propellor to full reverse but as it turned out, probably due to very slow idlespeed, the engine started to turn the wrong direction and slammed the pier at almost full ahead :) shit, but what a laugh...

[degsy2us]

Nice piece of turning on engine and prop alone. Just a little bit of skill there! Lovely sound.

[Johannes1955]

Love this video, great sound from engine!

[castirondude]

so when was this engine built? Do you need to glow it with a torch for a cold start? My dad worked on the Rhine and he said a lot of those engines needed to be started backwards with air pressure to back up. He said sometimes they lost it (river current) and had to throw out a rope and duck :-)

[SveinHaDD]

I believe the last semidiesel produced in Norway was in the very early sixties and this is one of the very late ones.

Yes, it have to be preheated with a torch for 6-10 minutes before start.

[castirondude]

I saw some of these reproduction Lister engines for sale here, they are made in India. I like engines that last a lifetime.

[castirondude]

gotta love that sound. Where is this?

[SveinHaDD]

Sandviken/Bergen/Norway

[castirondude]

The far north has always fascinated me, well, as do other remote places. I spent some time in the Yukon (Canada) a few years ago.

So, what is a semi diesel? Are these engines still being manufactured?

[detroitdiesel33]

Really good video! does the engine have avariable pitch prop to reverse? Where does it operate from?

[SveinHaDD]

Yes, it is a variable pitch propeller which is manouvered by the large handle. The propeller is running in the same direction all the time.

[angamoos]

what does that handle do?

[SveinHaDD]

The large one that is used most is the propeller pitch. The small in the middle is the regulator (throttle) and the last one is the clutch.
