Would anyone have an idea of fuel burn at hull speed on a 72' sportfish...
with MTU 12V396 TB diesels?
It's not a hat but a Vripack
The motors are 2285 hp.
I'm guessing it's not great.
Just trying to get an idea.
There is a beautiful one on Boat Trader for $150k if anyone is interested. Needs some kind of repairs but they don't say what exactly.

Is that the dreaded MTU 396?
If you can afford to maintain these beast, fuel economy is not a thought.
I can SWAG around 2 - 2.5 gallons per mile, then 2-3 GPH for each gen-set.
Sure is a pretty boat. If only I was still young & stupid, I could be looking in to her.Last edited by Captain Ralph; 02-28-2024 at 10:47 AM.

Well I kinda figured it wouldn't be that great.
That wouldn't make much of a replacement - fuel wise - for a 53MY
Nice for the sport fisherman or a really cool dock queen!

Those engines are more or less proper engines for a fast attack craft like a 160ft missile boat. Pretty mean piece of machinery!

Been a while since I considered another alloy hull. For S & Gs, Think I'll go look her over.
Time for the step son to step up to the ole MTU plate.
Rite off the bat, I'm not crawling any more towers. Anybody want a big asp tower??

Sounds about right for kind HP. I wonder what the cruise speed is with these motors in a 72’ alum SF. Has to be 30-35kts. Back it down to 20-22 and they probably sip fuel.

I had an aluminum alloy boat years ago. In addition to all the usual boat worries, you get to watch the CAPAC meter and worry about electrolysis eating up your hull.
