MTU 16v2000 diesel longevity and overal comments

A little more info may be needed. I would think that your asking about 16v2000 TE90
motors in lieu to the M- 90, to 94 series.
I have found that MTU has no more issues with problems any more than other manufacturers and if there is a problem than service bulletins are issued with factory
Upgrades to rectify .
Any engine is only as good as the maintenance that it has received in the past and MTU has a "W" schedule of programed maintenance so let's say that your motors are close to 2,000 hrs on the meters. That would now require a W-2 maintenance program be carried out. Cost for a W-2 for these motors is around $ 85,000 dollars.
Are parts for MTU's more expensive than say Caterpillar? Absolutely , besides the manufacturers difference , your dealing with the exchange rates of Euro vs Dollar . That being said MTU parts aren't any more expensive than MAN or Wartsilla it's just the major difference of domestic vs foreign made

The 16v 2000's are good engines and I agree with everyone's sentiments above. The issues I have seen with them have all been external issues. I've seen a lot of issues with accessory parts being of low quality or not lasting long enough. Starters, alternators, freshwater pumps having to be changed by 1000 hours on several of them I've dealt with. Not all at the same time. A starter here, an alternator on that one, a freshwater coolant pump on this one. The 1800 hp burn about 75gph at 80% load, so they're pretty good on fuel compared to others in their size.

The starters are Manufactured by Bosch (above average) the sea water pumps are Gear driven Gilkes and have bronze manganese impellers that will chew nails, the fresh water pumps are MTU Plant 1 Friedrichshaven manufactured and are prone to seal failure after a few thousand hours but they're on the every 1,000 hrs MTU check list when adjusting valve lash and The W schedule for a pressure / Bar discharge reading and a casing pressure test.

I've had to replace 2 starters, 1 on a 16v2000 with 800 hours and another on a 12v2000 with 300 hours. Freshwater pump on a 16v2000 with 1200 hours. A few injectors on the same 16v2000 and an alternator on a 12v 2000 with 650 hours. This is in my limited experience of dealing with about 4 sets of the engines.

Wow, that's quite a bit and certainly above average. Did the mains have PTO's on them? I've run across a Moonen that went through starters for three years until we finally figured that the Port engine was starting under a minimal hydraulic load but enough of a load to take the starter out via the MTU Blue Vision start timer relay that cranks the engine uninterrupted for 4 seconds or until the oil pressure opens the circuit to interrupt the start sequence. never really had that much trouble with Bosch equipment be it their alternators or starter motors and if there were problems it was always something like low voltage or a bad crimp on a terminal in the D.C. Circuit

No PTO, that was off of the gear. The starter on the 12v2000 started the motor and stayed on/running and wouldn't shut off.....I had to kill the engine and battery switch to stop it. The starter on the 16v2000 just wouldn't start anymore unless you hit it with a hammer.......

If the starter motor continued to run than it had to have continuous voltage to energize which would point to a faulty starter solenoid sticking closed on voltage. funny what a hammer will do to seat dirty or worn brushes on a commutator and as silly as it sounds , yes please, hand me the Technicians hammer, trust me the motor or starter WILL comply! Been there and not proud to say in a pinch, done that...

Yeah, but the hammer only works so many times....LOLOLOL

Did a little homework today, spoke with a guy at S&S in New Orleans (yes he actually called me back) I was inquiring about the MTU 16V2000 M93 (2,400 hp) replacement costs. He came up with a number (Engine only, no Tranny, no Controls, etc.) $525,000 each. He then added that on a re-power unless you could prove otherwise that you'd probably be forced to slide into the M96 @2,600 H.P. which are Tier III. When I inquired to the price tag, I was told it was north of $600,000! So OP, whatever you end up buying is worth fixing! That's a big number to re-power.

New builds have to conform with IMO tier III. a repower would be grandfathered into
Tier II and not have to comply. Still, the German iron in Bobtail arraignment sans
Gear box isn't for the weak of heart or check book. When you have a price like NEO was quoted that's a motor sitting in it's cribbage on the dock with out any ancillary sea water plumbing or electrics in the mix as far as a new build would be concerned. I priced two 16 v 2000 m-91 2,000 HP series last week and they were $400,000 each Bobtail in the shipping crates.

Captholli, would you please define Bobtail? I was told "just an engine" included a starter, etc. everything but the Tranny's and the Controls. A little explanation would be appreciated. Thanks.

A long block, the entire engine, but none of the wiring, accessories, motor mounts, things of that nature

Specifically, no transmission attached, thus it has a short or "bobbed" tail (like many hunting dogs). The same term applies to tractor-trailers when driving the tractor only, no trailer.

No gear box. Motor sitting in it's shipping crate on the shop floor.

Thanks guys...it was a new term for me...love increasing my vocabulary when I can....Kinda like "blowing the slobber" out of two strokes.

What would cause a rebuilt MTU16v2000m72 to produce excessive heat at the exhaust silencer to cause a fire
