5.9 vs 6.7 for an Albin 28

The QSB 5.9 380  is “close” to the size of a 6BTA 5.9 mechanical.  But a high-mount turbo would not be possible unless you had and extra $10+K to add to the job.. Major engineering and design/fabrication  needed.

You cannot talk about a 28 Albin with any degree of accuracy without knowing if you are referencing an engine box model (pre-2004ish) or the later production flush deck models.  The video was an engine box model.  The 5.9 is a tight fit in the Albin 28 EBM.  I would have to say that you would not get a 6.7 in there at all.  I was on one Albin 28 with a CAT 3116 (7.2L) and the deck and engine box were cut and modified to fit the engine.   There’s a reason that most A28’s had the Yanmar 6LP.  And the flush deck model is no better and worse in some ways.
