Indeed, but Volvo says nothing about not running for extended periods at
idle. They do seem to almost brag about how much charging current one
gets from thier souped up alternator at idle.

Could be marketing or it could be that the engine was designed and set up to
be more tolerant of idling than most small marine diesels which were
developed before electrical loads on small craft were anything like what is
common today.

The latter makes sense, the design is quite new and the advertising
specifically mentions todays higher electrical loads. The motor's
emissions meet or exceed EU and California Standards. I only installed
it last fall, put maybe 4 hrs on it before winter lay-up. It does beat
the tar out of the old single cylinder Yanmar, smoother, quieter, more
powerful, yet I think easier on fuel.
