Some advice? Make sure it's overflowing full when you head out. Do NOT rely on the fuel pumps to give you an accurate fuel calculation of how much gas you put in; they are notoriously short, especially the Circle K right by Safe Marine.
A buddy and I have both been bit by this, putting in what we thought was more than enough gas, only to run out on the way back in. To give you an idea of how short the pumps are, the guy that bought my boat went to fill it up there, they charged him for 300 gallons... it only tanks 230 max, 115 in each tank. NEVER use that Circle K!
