    Re: MTU 16V2000 in frame

    Well the inframe turned into a full rebuild as we discovered damage to the crankshaft. Took 3 months to get a new crank from MTU… cranks are made in India, shipped to Germany for quality control then shipped to MTU Michigan and then to Miami. That crank has already racked up quite a few miles

    We finally did the sea trial today.

    Here is a video of the full rebuild

    Cool video. Curious. GPH combined at 2000?

    110 gph combined at 2000 doing 21.5kts in calm water. Pretty good for a 116 footer.

    I mentioned it earlier in another thread in reply to an accusation of political china bashing

    This morning when I went to fire up the port engine to check the hydraulics after some maintenance, the starter spun but wouldn’t engage. It was just over a year old… I had the guys pull it and install the original that we had rebuild last year off the port engine. Turns out MTU now get starters built in china by Prestolite and to make things worst they no longer have parts to rebuild the older style starters.

    Glad I had a spare and I am keeping the original starter we pulled off the starboard engine.

    The funny thing is that yesterday we spent some time organizing parts and we stored the spare starter up in the attic behind the RPH after having it the ER for 15 months…. That jinxed it

    Thanks! .22 SMPG makes my .6 SMPG feel like an econo cruiser.

    Yeah, yeah, I know you drive a bigger house around. But it certainly does put my fuel burn into perspective.

    A friend of ours has a 2013 or 2012 80’ Hatteras MY with C32s. He burns about the same at 22/23kts…

    Most of the time we run at 11/12kts burning 25gph. Not bad considering.

    Re: MTU 16V2000 in frame

    Why does 4000 hours make me think these are like solid fuel rockets? Especially since the majority of cruising is at lower power settings.

    Re: MTU 16V2000 in frame

    MTU maintenance schedule calls for a an inframe at 4000 (pistons, heads, bearings etc) but this one apparently had suffered a raw water pump failure at some point which was not discovered right away. There were traces of rust on the crankshaft with scoring.

    Based on total fuel burn about 60% of hours were done on plane. We run quite a bit at hull speed and when I run on plane it’s usually at 1800/1850 or 55-60% load and 18-19kts. But previous captains may have been heavy handed and cruise at 75%…

    Re: MTU 16V2000 in frame

    I saw you mentioned your cruise RPM burn.

    Do you know the combined burn at like 700, 800, 900, 1,000 RPM? I have a guy thats wondering if he purchased a 70C could he get a 1.0 nauticle mile per gallon at say 9-11 knots.

    I figure at Idle its probably 6 GPH at about 6-7 knots, but wondering if it'll still get 1 mile per gallon at 10 knots.

    He'd also considering a 65c with CATS preferably. 16V92's I'm sure burn a little more.

    Anyone have any insight on this?

    Thanks
    Tony
