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
Greetings from central Australia, I love this video, the sound of that engine is mesmorising, a bit like an old Diesel pump jack engine. Thanks for the video, I often watch it as the scenery is so different from the Desert country we have here.
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.
Good god, what a lovely sound, and someone who knows his boat and his engine very well. I notice the boat turning, most of the time with no input to the wheel, as the prop rotates in only one direction is it just "prop walking" causing the boat to turn, one way forward and the other way aft. I'm guessing a pretty large diameter propeller on this vessel
@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.
@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
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?
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 :-)
Why is anyone even questioning the noise levels? turn it up. Besides the only way to reduce noise is to either restrict the air flow (exhaust) or create a seriously large silencer that does not reduce back pressure, two stoke engines require tuned exhausts ( i can't answer for hot bulb engines but assume similar results) and this will only give the desired results at certain rpm, most people do not have the time, knowledge, or money to engineer this. Four stroke engines do not need or want any back pressure no matter what people tell you, but don't take my advice on this look up 'David Vizard' there's nothing this man does not know from a scientific point of view regarding engine tuning.
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"!!!
Slipper nå bompengene... Hehe herlig låt altså 👍 Tenke seg til at min oldefar budde I det mest falleferdige huset som er oppi høgget der og det var falleferdig allereide i 1930 mens dei budde dar🤣
@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.
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...
Det er jo så tregt og overdimensjonert at tror ikke greier overbelaste det der. Når tenker på utenbordsen har en 3 cyl tohatsu 4 takt.Full gass ofte i en time og den tåler det helt bra på ca 5000 rpm.Dette her kan da ikke ha mye rpm.
@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!.
No! That only applies to modern type diesels . This is a hot bulb engine and exhaust back pressure considerably effects power. A 2-stroke diesel , Detroit’s being the most common have no relation to this engine other than it has a reciprocating piston. Detroit’s have blowers or super chargers on them just to make them run! This hot bulb engine would need something similar to make it possible to run right with restricted exhaust but then it would be a different engine.
