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?

@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.

@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!.

@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.

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

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"!!!

@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

[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

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

@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.
