fuel tank size

[lark2004]

About to look at fitting a fuel tank to my boat, and I was wondering how much fuel a late 60's to early 70's 40hp evinrude is likely to use. It will be fitted to a 15ft fiberglass hull (unknown brand) with a 12 - 14 degree deadrise, and a low half cab.

Re: fuel tank size

Can you measure the width, length and depth of the tank?

Re: fuel tank size

thanks phat, I was hoping that that would be the figure, I was thinking of a 60 to 80 litre tank, so that would give me ample to get around my local bay.
