I've been to the Yanmar website and also to boatdiesel.com trying to answer whether or not Yanmar uses common rail on their current six cylinder marine diesels. They do on their relatively new V8s (the 8LV series) but it isn't mentioned on their website and my tier one subscription at boatdiesel.com isn't enough to allow me access into that level of data. Anyone know whether the 6LPA-STP2 (and the like) have common rail? I ask because developing Tier compliance will (seemingly) nearly require it.

I have to add that I've twice asked this question to Yanmar USA's customer service and have twice been told to ask my local dealer.

My limited experience with the LP series found that they are LOUD. To your knowledge, has that changed at all? I've found that the switch from direct injection to common rail can make a substantial difference but Yanmar doesn't publish dB levels like some other manufacturers (Cummins, for instance).

We still have them in stock. Let me know.

This isn't the story that I've heard. I'm told that the mechanical 315 6LP isn't Tier-compliant and, despite these being new engines, can only be sold for re-powers.

Nope. Not true. The engines we have in stock were manufactured before the end of last year. They can go in a brand new boat. We sell them every week to new boats. We are down to about 15
