Are the fuel tanks hooked together
Is there a crossover anywhere. I ask because I was wondering if you could run one tank empty and still make it to shore on the other engine?> Thanks in advance

Not from the factory. Some have removed the tanks and run a cross over themselves. Unless you are removing the tanks for another reason, its a lot of work, just to run a cross over.

Some Fountain fuel gauges will show 1/4 tank and really be empty, so keep an eye on that for your first few missions. Personal experience. They can be calibrated.

Thats ~ 55 gallons per tank (93 octane at ~ $3.55/gal). Don't know how much is in each tank, but that should last ~ 2-3 hours run time at cruise rpms ... or just over 1 hr at WOT. The 29 we had with a 575 LOVED fuel more than any other boat we owned. Was always amazed how thirsty that engine was.
I know the tanks in our 35 Lightning twin step were not connected - each tank was hard plumbed to one enigne. We would pull into the middle of the gas station and run a pump hose from a pump on each side of the boat so we didn't have to jockey the boat around ... downside was that we would effectively clog up the gas station, though, until we were done.

Plumbing a jumper line from tank to tank is not that hard to do in the engine compartment. That's the first thing I did when I bought my boat. It was a bit easier with the engines out tho. All you need to do is break the fuel line somewhere after it goes through the bulk head into the bilge and put a T on both lines. Then put a jumper piece of fuel line between the 2 T's. You'll have to put a manual shutoff valve somewhere in that line to keep the engine drawing off the required tank. You'll also need a shut off valve on each line to each engine too. That one stays open all the time, and the one between the 2 tanks stays shut. In the event that one tank runs empty, you open the line between the 2 tanks, and shut off the valve from the empty tank so the empty engine can now draw from the opposite tank.

Now, THAT'S a good idea !! I can't believe I never thought of that. Phuck everybody else, if I gotta wait, so can everybody else, cause when you try to jockey the boat around to the other side, there's always an idiot that pulls in right where you need to go. LMAO All tho, I fuel my boat at home.
