Fuel Tank Size

[Water Rat]

I Have a
1978 23' Sceptre with a 7.4 liter Bravo One. My boat did not have the small in-deck live well forward of the engine compartment and came from the factory with what I remember to be a 72 or 80 gallon aluminum tank that was installed with some foam on the sides between tank and stringers.

At about the twenty-odd year mark, I decided to replace the tank (which to my amazement had not sprung any leaks yet). I needed more range and finally decided to go with two tanks. My aft tank, immediately in front of the engine compartment, holds 65 gallons; the forward tank, approx. 45 gallons, which I had fabricated in an odd shape to take-up a small porton of the fish box but also extends forward and underneath the fish box. This configuration allowed for aprox. 20 extra gallons without consuming too much of the fish box.

I typically run off the foward tank first, then know exactly what I have left to get home - makes fuel management fairly simple. It took a bit of engineering to get the right dimensions and configuration for the forward tank; believe I still have the drawings if anyone might have a use for them or wants to recreate what I did.
