Eric, I can answer your question because my R25 was inside Mack Boring's (our area distributor) shop when Mike brought in his new R27 for his "hose job." The shop is located off Rt 18 in Middleboro, MA which covers New England & the Great Lakes area. Headquarters are in Union, NJ. They also cover Virginia and both Carolina's through their branch in Wilmington, NC.
Norman, the mechanic working on Mike's boat in Middleboro, took a break and phoned me, on Saturday, to update me on my boat. In a previous TugNuts comment I reported how my secondary fuel filter (the one on the engine) exploded through the rubber seal (actually herniated) when I turned on the boat. Sprayed fuel everywhere at enormous pressure.
Three weeks at the local Yanmar mechanics on Cape Cod who made a mess leaving parts and actually had the nerve to ask Norman to clean it up since the boat had to go up to the distributor anyway. This after he was nice enough to drive down to the Cape to spend a couple hours to help them try to diagnose the problem in my boat. No soap, though. Norman was shocked to be standing there when the locals called to tell me that thought the engine had to be removed... He immediately, politely suggested transferring the boat to Middleboro, to which both the boatyard and I agreed.
Norman thinks he has it narrowed down to the high pressure pump having failed in some way. The pressure at the injectors on the common rail is high enough to "take off your finger." No one seems to have heard of a pump failing, including Cascade, the distributor in Ranger territory in Washington. It may be rare, but I'll document his success or failure here for others to learn. Norman is even having trouble finding one. Of course, I immediately emailed Andrew begging his help.
I've had some problems (hoses and now the pump), etc. and just knowing we have a competent Yanmar mechanic is a great relief. I'm tired of "Yanmar authorized" mechanics in Florida and Mass telling me, "Oh, is that a common rail engine? I've never seen one before!" Take a course at the distributor! They offer courses for owners and dealers; I think Mike of Knotflying took one. These engines are everyones' futures. Next, they'll be telling me the engine is "cute." So far, I ditto Mike's kind words for Norman and Mack Boring. BTW, I believe Peter up at Winter Yachts or Salem, MA dealer is a diesel mechanic. I bet he could figure it out, but it's a relief not having to drive that far for us south of Boston owners.
