Boat Info
1979 sea ray sdc 240
Engines
5.7
Hello, Im about to pull the trigger on this boat but cant find info on the ranges these boats can do.
What can a full tank take you for a single engine, 5.7liter, does anyone use them for longer range trips?
 
No clue what 'a full tank' amounts to in that case, but you might find a start here . . .

Sorry wanted to see because it appeared alot had the 1979 sdc 240, figured they would have input on the range based on the factory tanks installed on their boats. Thanks for the link, based on that it seems pretty good
 
I suspect the number of that exact model out and about is less than you perceive.

If you go here: Sea Ray Owner Info and scroll down to near the bottom, you will find Owners manuals, etc for a lot of models. Be aware that it is kind of slim pickings for anything that old. You may find something similar that will give you an idea, maybe not.

Good Luck. Don't expect a cruise ship range from such a critter, gas is heavy and weight is not our friend.
On the upside, where thirst is concerned, that 350 will do much better than my 7.4 does in that regard.
