36 express trawler with twin 270s

Post by arcticspud »

Does anyone have any fuel flow numbers/performance numbers? Is there any vibrations with a twin 36 ET? We are looking at Indigo and it has twin Cummins 270s.

Blue Mooon has twin Cat 300s. I developed this chart based on the Caterpillar performance chart. Later, after I had Flo-Scans installed, I was able to confirm the gallons per hour of fuel burn to within a few decimal points. Sorry that the alignment of the chart isn't perfect but you can see the point. INdigo should be similar, I would think.
