Topic: Universal 5411 Fuel Economy

I'm wondering if there is anyone out there who as this Universal Atomic 5411 2 cylinder 11 HP diesel engine in their boat and can advise me as to what fuel economy I might expect.  I've got an 11 gallon tank and am wondering how many miles/hours I might be able to get per gallon/tank etc. 

Planning on running this boat down the Mississippi River to New Orleans and will be using the motor almost exclusively when I'm on the rivers.

Thanks,

Brian

Re: Universal 5411 Fuel Economy

speed is a big factor. I have a one cylinder 9.5hp diesel. When going 4.5 knots I burn .63 liters per hour. At 5.5 knots I burn  almost twice that.
