I'm trying to guess how much fuel my boat will use on a cruise and what kind of range to expect. I just bought a 1987 21' sea ray sorrento open bow boat with the 260hp v8 (350 cu in). It weighs 2800 lbs dry and will likely be around 4k lbs to 4500 lbs displacement with my family and gear on board.
I have a 44 gallon tank and am guessing I'll be using 8-10 gph at a cruising speed of 3000-3500 rpm which is probably about 25 mph. This equates to a range of about 100 miles.
I'll never be able to check this in the small lakes around here, it's all sitting in a cove or skiing. Can anyone tell me if I'm close in my expectations or not?
