The boat is a Wellcraft 1987 sport fisher 23' with a 99' mercury 200 saltwater(carb).

I am in fort lauderdale and will spend most of the time putting around at idle up to 2k rpms(mostly manatee zones).

Most of the reefs around are less than 5 miles offshore.

The gas tank is 128 gallons and the boat weighs around 3000lbs with motor(minus gas/people/equip). I would venture a guess of an average 12 miles per outing.

Any advice/info into how much fuel I would use typically?

I would guess around 2 mpg at 2000rpms, perhaps 2.5 mpg around 1500 rpms

figure 2 mpg cruise and then double it for your figures... warm up time currents wind waves no wake zones... a safe number for your wallet would be to bank on 1 mpg and hope to get better for the whole trip
soo count on 15 gallon and be happy if you come in under that

That figure comes from the boat weight plus engine.. fuel alone will weight 700lbs on top of that(not counting people and 4500 seems about right(loaded).

I have owned a similar boat/engine combo before, and often did similar trips to what you are describing. It was nearly always between 10 and 20 gallons i would burn per trip.

A Wellcraft 230 is #3300 w/o motor. By the time you add in motor, batteries and gear you’re pushing #4200 w/o fuel. A full tank will put another #1000 on you.


I run same size and weight boat with a 200 HP outboard. On smooth water, I’ll get ~2.2 mpg @ 4400 rpm (27 kts). If it is rough, you can cut that number in half.

When trolling @ 1000-1100 rpm, I burn ~ 2.5-3 gph, which comes out to ~ 1 mpg.

You can throw the 5 miles out the window. Five miles on the water looks like 1/2 mile on land. You'll find yourself 15-20 miles out of port before you know it. Pretty easy to burn $100 of fuel and oil in a morning. Pretty easy to burn up $200 in fuel and oil in a good day.

I understand but living where I live I have access to 3 reef fishing spots and backwater spots within 5 miles.. Of course I could run 15-20 miles offshore but dont see the point.

1mpg seems about right.

I'm have easy access to some of the best surf fishing in the world, yet I have a boat. Why? For the same reason the chicken crossed the road. :lol:
