Key largo 206 has a motor 200hp, how many miles per gallon would you get traveling at a moderate speed?

Question

I will be renting this boat and am trying to figure out the gas mileage so I may calculate this into my spendings.

Answer 1

A 200 hp motor uses approximately 20 gallons per hour at full speed.  Slow down and use less.  If you are going 40 miles an hour and you burn 20 gallons per hour it comes to 2 miles per gallon.

Answer 2

Since most Key Largos are rigged with Yamahas here are some specs for a 4 stroke. The 2-stroke is pretty close. Hope this helps

Answer 3
