Can anybody give me an estimate from experience how many miles per gallon I can get from a Universal or Atomic 4 gasoline 30 HP engine running at say 2,000 to 2,200 rpm.
I'm pushing a 32' 10,500 lbs sailboat with 6.7 hull speed.
I just bought this boat and need to move her 80 miles not knowing if I can sail her due to prevailing winds and only have a 24 gallon gas tank.
Any estimate will be appreciated. I know there are many of these 30 HP inboard in 31' plus sail boats out there and somebody must have figured this out. Previous owner can't tell and/or doesn't know.
