Fuel consumption - merc. 502?
Does anyone know the fuel consumption on a merc 502 at cruise speed contra full speed...? The boat is a 25 feet scarab and everything runs great except for the fuel gauge... 2 times I've ended up getting towed to the marina by nice people... both times I was sure the fuel would be enough for the trip...

30 GPH? You are talking twins right?
I have a 454 Mag in a '24 Superboat and at 3500 RPM I average about 10 GPH. With a 502 and your boat is probably a little heavier than mine I would guess maybe 15 gph.

Hey Mark,
I would say that your gas consumption sound high. The MPI motors are probably more fuel efficient. My boat weighs about 3500lbs. It also has a 7' beam. I can cruise at 50 mph all day long on about 10 GPH.
