Depends on which 260HP it has. The early style 260 rated at the flywheel(86 and older) were not the best on fuel, burn roughly 12-14 GPH at cruise. The 87+ got revised cylinder heads(and some got roller cams), and then in 96-97 the VORTECS came out and made another leap forward. The SEARAY I redid last year vurned roughly 10-11 GPH running at 3200-3600 RPM cruise(weather permitting), and cruised in the low to mid 20's. It averaged a bit better than 2 MPG loaded heavily with a good prop. Originally the boat was rated for about 17 according to some SEARAY literature I found. On a 248 COASTAL though, I don't see 2 MPG being that hard to obtain. And if you can find a later model EFI it will pay for itself.
