I had my boat out on the water this weekend... I was finishing up about 24 gallons of fuel with about 1 oz. per gallon fuel system cleaner mixed in... Well I was just about empty so I pulled into the marina to put about 12 gallons gas in (I didn't put fuel cleaner in this time). I made it about 1/4 mile at the most from the marina when I was going wide open and the engine sputtered out on me.<br /><br />All indications were pointed at the marina's fuel quality. I spoke with the marina guy later that day and he did not admit to any other reports of problems with his fuel. He claims his tanks are small and there is high turnover there. I believe him as his marina is very busy all the time even with the local law enforcement boats.<br /><br />And if it couldn't get any worse, after it died, the battery did not seem to want to turn over the engine. The day before I charged the battery over night and half the next day with a new inexpensive battery charger and it would only hold a 75% charge at the best. The battery was bought in the last year.<br /><br />Problem one... Why would my battery only hold 75% charge after charging so long? And when it does show 75%, it will hardly turn my engine over. I checked all my cables and they seem to have good connections... I even changed the connectors on the ground cables to the engine.<br /><br />Problem two, once I get the thing to turn over and try and fire, where should I start to correct the gas problem?<br /><br />Please help me!
