Everything eventually is no longer supported. However, diesel marine engines have generally remained supported for many decades through one channel or another.
rc, if I already owned a boat with either DD 2 or 4 strokes I'd just ride with them without any concerns, not saying either are bad engines. Because we are looking to buy, would put less value on the s60 engines because no longer being mfg'd and now owned by Rolls-Royce according to PacBlue...surprise not MTU. The 2-strokes are everywhere and suspect they will be supported until the numbers get low enough not to be profitable, not as sure about the s60. Most of the boats on our radar have the Cat 3406E's or C18's, which is my preference based strictly for parts, service, and dependability, one has the s60's which has been discussed very well here and satisfied my curiosity.
Rolls-Royce owns MTU. Many of the CAT's you look at are no longer manufactured either. Or any other brand. Today's engines are not yesteryear's.
The 3406 has to be one of my Cat favorites. They are no more also. Just again, lots of them out there.
I made that same statement about a year ago and was quickly schooled by K1w1 after he was at Factory 1 in Friedrichshafen where he says the foundry is still producing parts from castings and can even build a complete motor when needed. Apparently MTU has so much of the 396 series in transportation applications such as locomotives and earth moving equipment that they'd be short sighted not to support them. 15 yrs ago I got a tour of the Eiffel Towers dedicated power house and was not surprised to see 4 MTU 12v396 being used as emergency back up generators. I'll take K1w1's word on this since he lives and works in the fatherland...
I realize the 3406 is now the C15 and likely has updates. No on C9 or C12(3196). Cat has that huge service network. I might still do the s60 if the right boat came along.
That's an interesting comment considering they are putting 4 new 8V396TE54's on every new LCS built by Austal in Mobile, Alabama.
No mention of S60 not being manufactured, they are still availed for the near term. USCG RBM is filled with them and parts support will go on longer than most boaters active ownership. Corporate ownership of engines manufacturers is an evolving game, like Volkswagen owning MAN, etc.
Try to get an injector pump for an older 8v396's. They go for around $60,000 I've been told, IF you can find one anywhere. Perhaps they re-iterated that smokey POS engine and re-introduced it. But if you have one of the older ones, lots of parts are impossible to find and they're junk motors......lots of issues. Then again the LCS's have had major issues and horrible engineering so the 2 match each other.

Diesel Engine Traders has no fewer than five brand new 12v-396 motors listed for sale 10 minutes ago.... Tons of used units out there also. These motors are found in fast patrol craft for virtually every countries coastal defense force.
Your knowledge of an LCS type vessel outside of reading headlines wouldn't fill a Thimble, let alone the engineering behind the scenes. Stick to what you know.
It took a couple of generations of the LCS program to put reliable generators in the LCS class vessels. The 1st generation of Freedom class vessels had four Isotta Fraschini v-1708 generators and the engineers couldn't keep them running on a consistent basis, huge problems with them. I commented on YF a year or so ago on this topic. Hard to believe that Isotta / Fincantiari USA has that kind of juice to lobby the arms service committee and the powers to be to place a known dog of an engine in our naval vessels. Happy to see they've switched to MTU 396 series.
LCS 1, Freedom class built by Marinette Marine / Fincantieri in Wisconsin still have IF gen sets, unlike the LCS 2, Independence class built by Austal in Alabama which have MTU. Both shipyards are still delivering new vessels.
That's a shame then as the Isotta's are very problematic motors and have lead to major down time for these vessels. I've read where the Gen 1 LCS units had Fairbanks Morse/ Colt Pielsticks CODAG arraignment with GT's but haven't heard nor read if the second gen have updated their prime movers. F.M. has a proven platform for propulsion with proven technology and reliability.
The LCS has been nothing but problems. Major electrolysis, gear box failures, engine issues, generator issues. In the several years since the first one has launched, none of them have even come close to completing one tour successfully. AND, when exactly was the last mechanical 396 put into a yacht????? Have you ever run a yacht with 396's???? They're stinky, smokey, problematic, and parts cost a small fortune. You can't sell a yacht with 396's in it, 16v92's are twice as desirable as 396's and that is not saying a lot.
Please tell us about the electrolysis issues , You've had time to google this topic so please respond and enlighten us... Please do it within 5 minutes or we might think that your searching Google again. I like you J, but you seem to step off of the deep end of the pool with comments about 396 series motors and then don't respond when you learn facts that differ from your own. Go back through my posts and you'll see several times where I say , "oops" sorry, I'm wrong or I stand corrected, thank you. You on the other hand don't seem to have that ability to humble yourself and admit when your wrong or out of your depth. Its easy, I do it all of the time when my fingers over-ride my brain.
