Mid speed diesel engines

Hi folks,

I am making a 35m steel hulled displacement pleasure boat.

I have searched a lot for mid speed diesels in the <1000 hp range really to no avail.

The Lugger L6170 is no longer available (it was a 24 litre Komatsu), the MAK M20 is available but it is really too big, and I have NO information on anything in between that is a viable economic proposition.

I need 620kW...anything a bit more, up to 1000hp is OK for the owner as we can then get max speed up a bit if necessary, but I cannot find any engines that cibe me 1000hp or slightly less without getting into high speed diesels such as Cat or Cummins.

Any ideas would be gratefully accepted.

 

A quick search on "current models" at boatdiesel.com produced the Niigata 6M26BET with 625kW @ 400 1/min and "continuous duty" rating. All other results were engines which run at (much) higher rpm.

Hope this helps a bit...

 

did you try Deutz, they are very easy to talk to
try the Wien branch ask for johannes, tell him Stuart sent you
becker.j@deutz.co.at
you know those long range longliners and tuna boats that venture Japan down to NZ and clean across the Pacific, they all have those slow engines

wake up Lubs you bin on abt thsi for a whole year)

 

I'm sure they are producing them in India. Something like Gujarat only bigger.. http://www.fieldmarshalengine.com/p_wcde.htm#1 Note that these are highspeed

 

Yeah woosh, so right, I have done the build and general specs though, so I am getting there mate. Ta.

 

I should have said also that I do not wish to spend over $500,000 for an engine, that is what they are asking for German engines....unreal prices.

 

this is my dream, for sale at 700k, with proper engines, converted North Atlantic trawler 119 feet, flamin' bargain

 

Nice, some of those old girls really are good buys.

I bought a 160 footer in the Pacific once for *0k. She was "retired" because it cost too much locally to put her back into survey. I managed to do it for under 200K and she was a great Island Trader again.

MAK 500 hp@ 575 rpm.

 

Baudoin, Caterpiller, Kelvin, M.a.n, Scania, Duetz

 

The 1st is to forget (I do´nt say crap), the second may fit, Kelvin is by far to heavy, MAN is high tech, high rev., Scania is too small and like the first, and DEUTZ has one engine in that range, the TBD 616 (not made in India Teddy) call William Knudsen:

Mitsubishi maybe worth a look too.

i have heard baudoin are bad but can several hundred french & italian fishermen be wrong ,the're very popular,how can kelvin be too heavy, whats the boats tonnage,

 

Peter
I assume the fishermen are looking at the price mainly, otherwise I cannot understand their decision.
The Kelvin engines of similar output as a Mitsubishi is about 1000kg heavier.
The boat is a slender 90´ of about 80tonnes.

The problem still exists, I am looking for a mid speed diesel, from 900 to 1200rpm, of 620Kw power, prefer inline......so far, for the boat of 220 tons, I have found no engine available.

The beautiful Komatsu (Lugger) is no longer available......

 

have you considered rebuilding an old Brons or Sulzer

 

peter,

I am all for a rebuild, unfortunately the owner wants "new"....he will not accept a rebuild, even though we all know, the rebuild IS a new engine if it is done right, unfortunately I cannot convince him....such if life....thanks anyhow mate.
