I know people who only averaged between 10 and 15 gallons a hour consumption. Not an efficient trawler in my opinion.

These folks are not running displacement trawler speeds.

Or have large boats.

10 GPH is at least 150hp , 15 Gph well over 200hp.

It takes 3 hp per ton to operate a displacement boat.

So at 15 gph the boat would need to be about 75-80 tons .

Or they are going too fast for trawler speed fuel economy.

With that size engine 7 or 8K cruising was not in mind.

If you want 1 1/2 to 3 gph cruising it will need a different boat.
