Man900's software update

I've never heard of a software update. However, if you have the engine serial number, call MAN North America and ask them, they're located in Pompano Beach, FL.

I believe the update in question is related to the cheating by Volkswagon and my MAN on fuel consumption and emissions.

I doubt it has anything to do with VW. MANs are marine diesels and follow different rules.

Marine Diesel specialists in Fort Laud is also an excellent man dealer. The owner there Pete, is very knowledgable and will take your call.

The 58' searay is a good running boat and cruises at 28.5 knots, but is a little light on range.....just under 200NM at cruise safely. I ran one from South Florida to Conneticut once.

No, not with VW. MAN was doing it too and had their own problems.

I would talk to Marine Diesel. Whatever you get done, get it done by a MAN service center, not a Marinemax.

Here is a link to MAN's cheating. http://shippingwatch.com/carriers/article8115043.ece

Now, that was just my guess. This may have nothing at all to do with that. That's why I'd speak to an expert.

Perhaps the only person who is recommending the software update is the person that told you that, because nobody else has heard of it.

Hi Mike
I have a layman's question:
Did you post your question to MAN on their site?
I think this is the place to start, from that point you can verify thier answer with the experience of the forum members.
MAN might deny such a S/W update, than Capt J last response is more than logical!

What age is the Sea Ray?
Many of the early Man Common Rail full electronic engines (2004 till 2007?) I am encountering need a software update for the engine hour reading.
Basically the hour reading goes faster. But apparently it also might affect full diagnosis review problems according to Man mechanics I spoke.
Quotes vary, in Malta is about 2k EUROS for both, in Italy I was quoted 3k. Both quotes are for R6 800 or 730 engines and include fast courier shipping with return.
For doing this you need to ship the control unit in the engine room to Man Germany office.

I have encountered this software problem in three Man marine engines varying from 8 to 10 years age in the last year.
If marine support was fair I think this had to be done to Mans own expense. It is a pity cause I think the Man R6 is one of the best engines in its class, if not the best.
In my experience the software glitch never effected performance or reliability, but when you do a Man engine survey or diagnostic it does come up.

Speaking of which. I agree Liam

I have managed/maintained a set of 1100 hp common rails 2007 for about 5 years now. About 3 years ago the hour meters both read 99,999 hours within 2 weeks of each other and stayed that way. Turns out MAN had the hours recorded to the wrong side of the alarm monitoring circuit board. The ram instead of the EPROM or something like that. We had to pay $4500 for the dealer to change the board with "updated" (The German engine manufacturers favorite word for a poorly designed part they redesigned but make the owner pay for). These circuit boards came out of the Engine room mounted engine brain boxes.
