Size and Weight of Bukh DV20 ?

I am looking at replacing my inoperable Atomic 4 with a ~20HP diesel.
I have found a fair deal on a Bukh DV 20 NR with transmission, and am considering this driveline for my repower. By all accounts it is a simple to maintain and reliable to operate engine, that is uncommonly heavy... but NOWHERE, not even in it's own manual, does it state HOW HEAVY the damned thing is!

I know the A4 weighs 310lbs, and am hoping a diesel with half as many cylinders won't weigh TOO much more!

I would also like to know what its physical dimensions are. It is going into my '74 Cal 29, which has plenty of room to work on the A4 from every side and angle I am assuming a diesel with half as many cylinders will be even smaller

I had a long relationship with a Bukh, and wouldn't have another one.
It's all right till it breaks, makes volvo parts pricing look good.
That is if the part is available at all.

Re: Size and Weight of Bukh DV20 ?

Attached is a drawing with dimensions. If I remember correctly, the weight is about 220 kg. I never had problems getting parts--I used a supplier in NJ (I don't know if they are still in business) and LSM Diesel (LSM Diesel Denmark) in Denmark. You should be comfortable doing all work yourself, as there are no knowledgeable Bukh mechanics in the U.S.

Most Bukh engines were sold with raw water cooling, and scale buildup could be a problem. Mine wasn't exactly easy to start when cold, but ran happily once it got going.

It would be replacing a raw-water cooled A4, so I have to deal with scale either way.

Thank you for the specs!
