I am by no means an expert, but putting a combination of 30,000 some odd hours turning a combination of a Detroit 671, a cummins qsl 9 (electronic motor), and a cat 3406 aboard my various draggers, along with a 80hp ford lehman aboard my oyster barge, not counting Spirit with it's Volvo 110 d3, I've seen my share of black smoke.
Diesels are meant to be run, and run hard.
Best advise, run your boat like you're stealing it 15 minutes every day.
I normally see a puff of black smoke whenever I start up my dragger , especially in colder weather. Can't say I've seen it happen when I start up the Volvo aboard Spirit.
As a side note:
I had a Volvo guy aboard Spirit while in Charleston back in January, due
to an electrical issue with the motor. He explained to me that the first production of the 110 d3 is somewhat of a mystery to many Volvo technicians. The motor is a bit of a hermaphrodite(sp?). The service manager himself came aboard to work on the motor. He located the short.

I should have added to the initial post. The day of the "puff" was in the middle of a multi month long sail for the owner. Just first start of that day. The engine had been run every day for months.
Speaking c JP he confirms a quite knowledgeable Volvo diesel mechanic runs a Volvo aftermarket shop in the marina in la Marin in Martinique
I would imagine he'd have good insight.
Agreed. I took Dave's concerns not as a diagnosis of cause but just noting an irregularity. Since then I have run both engines many times and not seen a repeat of the survey puff and sheen...so I think I am ok. Porter will need to look at the recent run time history of the boat to see if this is just an artifact of an unused vessel that will go away with more frequent activity.
Oh, and Mark, thank you for reccomending Dave. He was great.
