is it true there is only one gas tank, feeding both engines,
on the Twin Engine 310 Signature Chaparral (2010)?
 
I don't know that particular boat but it's not unusual to have a single tank with twins. My 32 Blackfin had a single 304 gallon tank feeding both engines.
 
My old Chaparral was the same setup. The generator pull from the same tank as well.
 
The Silverton 45 that Walter has is 1 tank.
Not a fan of 1 tank, but in reality not sure it matters much.
If you get bad fuel, odds are you are gonna add it to both tanks.
Biggest issue is if you run out of fuel, your out of fuel.
With 2 tanks, you can switch to tank that has fuel left and both motors won't die together!
 
Yes that is correct, one tank, and it even has two fill ports.

A friend with a 43 Viking has one tank under the aft king berth.
 
One tank makes no difference, not sure your concern?
 
Rich,
The one tank setup is probably because it's a belly tank. My boat has a 100 gallon plastic belly tank and if I had a generator it would also feed that as well. I'm guessing but your probably thinking it's not big enough and if you cruise long distance you are probably correct. The good thing is Long Island has plenty of gas docks so you covered. My biggest worry is if I ever need to replace the tank it would be a big deal!

Look at it this way. You only have to replace one tank when it starts to leak.
 
All the pluses you guys point out for one tank are pluses for two tanks.
With two tanks if you run out of fuel or a tank leaks you are not dead in the water.
If you get a contaminated tank, you are not dead in the water.

I think 2 tanks offer a safety feature that 1 tank doesn't.
 
Not sure where you're coming from about running out of fuel?? If you're carrying x amount of fuel, x amount is the same whether its in on tank or two tanks.
My Silverton 34C had two tanks, but no crossover, 45C has one tank. As mentioned previously, when you get fuel, I assume you're filling both tanks or one tank from the same fuel station. With that said, if you get bad fuel, it does not matter if you have one tank or two tanks of bad fuel. If I had a fuel leak, one tank or two tanks I would not run the boat and would call sea tow. Personally, I would be more concerned about what color my cup holders were as opposed to one tank or two :)

Depending on your boat, one tank replacement would more than likely cost you less than two tanks. If one tank leaks, obviously the other tank will follow and need replacing. In my Silverton 34C, the fuel tanks (2 of them) were mounted on the outsides of each motor. If they needed to be replaced, both motors would need to be removed to do so. With the 45C, the one tank is mounted in the stern of the boat and could be removed without touching the motors.

Fun Time,
Your question was a good question, but unless someone else chime in on an advantage, I see known based on my experience. Good luck with the hunt on another boat.

I like having 2 tanks because if one tank develops a serious leak offshore I can still get home on the second tank. Otherwise there's really no advantage and with a gas boat if one tank developed a leak you're not going anywhere on the other one anyway, you're shutting down and getting towed to avoid blowing up!
 
Walter, Didn't you run out of fuel with one tank?

2 tanks don't drain evenly. If one runs out or gets contaminated, you can still run the other motor and get home or continue to go slow until seatow comes.
With one tank, like you have and like what happened in Montauk to you, once you run out, your are dead in the water. No genny. No engines. So now until help comes you can only anchor down.

Also if that one table gets contaminated. Both motors get shutdown. Not one. Both. With two tanks, other tank and motor will keep running.

A leak is a different story. Diesel you can still run.

In my boat I can also transfer fuel from bad tank to good tank. Or if empty I can add fuel to empty tank with tank that still has some fuel.
 
Dave,
one tank two tanks or ten tanks, once you run out of fuel, there is no more fuel. Hey, 0 + 0 = zero no many how many tanks you have???

"A leak is a different story. Diesel you can still run." Don't think that would be smart, but you can do the same if you had one tank???

"Also if that one table gets contaminated. Both motors get shutdown. Not one. Both. With two tanks, other tank and motor will keep running" Really, please elaborate on that, I must have missed something here. :) If you fuel both tanks at the same fuel stop how can what you stated actually happen???

Just saying

Walter
 
Need to make this simple, because I am a simple guy.

Silly me, but when you run out of fuel, that means you have no fuel, my second fuel tank never created fuel when I ran out of fuel, was that an option i missed????
Does 0+ 0 still equal 0 ???
Lastly, if you get crap fuel, and it goes in on tank or ten tanks does that make it better fuel???

I am surely missing something here???
