fuel gauge

[bj]

I had 1977 Sceptre and if my memory is corect it had an 85 gal tank with around 72 or so useable gallons. It was an I/O so the tank may have been smaller than the outboard version. Those gauges are so inaccurate though it could easily read empty and still have 25 gals in it. If you run it down that low quite often it would be smart to install a fuel monitoring system so you will know exactly how much you have burned.
