I was just checking out the new 2008 240SD and noticed that on fuel volume it says 65gal, but usable fuel is 58 gal. just wondering if anybody knows what that's about, were's the other 7 gals? I's that the same as on our older models? It doesn't say that on there specs. Also I noticed the fresh water holding tank went from 20 gal. to 18 gal.
 
IMHO I think it is the same as our 2006s. I've always figured 60+- gallons of usable fuel. If you notice the fuel pickup is not on the very bottom of the tank, same as on the water system.
 
I see, haven't looked at that but I guess that would make up for the 7 gal. So really we have 58 gal. of fuel to use instead of 65.
 
Just a guess but maybe he fuel tank has an expansion chamber in it to deal with expansion and contraction of fuel due to temperature variations. Normally you cannot fill that chamber with fuel. That may be why the two numbers are different.

On the water tank, ever since Sea Ray offered the Corsa on the 240SD they have had to use two different size water tanks.....a 10 gallon tank for those with Corsa and a 20 gallon tank for those without the Corsa. The smaller tank was to provide enough room for the routing of the side exhaust. Maybe they have now gone to a single 18 gallon tank that will work regardless of whether they install the Corsa or not.:huh:
 
Well I sat down this week and read thru all my manuals, it claims that on my 06 that there is 61 gal usuable fuel, three gal. more then an 08, still curious of why that is and I wonder if the computor is calibrated for 65 or 61 gal. Not that you should ever let the tank run down that low, but it's something that just seemed odd to me. also it stated in the manual that I have a 24 gal. fresh water tank, all the specs say 20, maybe it all has to do with expansion like Dave S sayes, who knows:huh:
