Never. I know of no reason to run the gasoline out of any motor. I used to do that with a chainsaw until the tech at the shop said it was bad for the carb. He said if I were concerned then use a stabilizer.

Running a two cycle engine out of gasoline also means running it out of lubrication. There may be enough residual oil left on the bearings and cylinder walls, but then again, why take that chance. It was a standard practice years ago.

I'm speculating that the practice began when folks took the motors off their boats, and laid them on the floor of their trunks or pickup beds for transport. It kept the fuel from leaking out and creating a mess.

To my knowlege, it was never done in lawnmowers, vehicles or any other engines, be they two or four cycle. It was a practice primarily used in outboard motors. I see nothing in my owners manual that suggests running it out of fuel. In fact, it is impossible to do in most bass boats if not all, because the fuel line cannot be unplugged at the motor.

At the end of the season, or when a motor will not be run for an extended period is another matter.

The gas gauges in my boat show empty when they are really 1/2 full so I would just let them run out switch tanks repump the bulbs and restart. My mechanic suggested that this was not a good thing since as the wngine was coasting down it had no lubrication for a few revolutions!

I don't have the patience for that. Even after removing the fuel line the motor can take quite a while to stall out.

Every time you take your boat out of the water and trim the motor up the fuel will leek out of the front of the carbs or the EFI box if you have ever noticed that there is always two stroke oil in the bottom of your pan when the mixed gas leaks out the gas evaporates and the oil stays so i see no need in running it out of gas

You might be able to adjust that problem. I had the same issue in my procraft. Locate the gas level sensor on the top of the tank, turn the key on but do not start the motor. Rotate the sensor (loosen it up if necessary)clockwise or counter clockwise. Watch the gauge as you do this. I was able to re-calibrate the gauge. I hope helps.

By the way, I never run my Merc 150 out of gas. It stays hooked up.

I have and always will completely run my motors out of gas at the ramp. I have had to have my the carbs on my boat cleaned and synced when I bought it and for the cost I would rather just run the boat out of gas. I don't use my boat every week or even every month so running it out of gas is piece of mind for me. My dad has a 1978 evinrude 35hp that he has always flushed and run out of gas when he gets home from the salt water and that motor runs like like a champ. He recently let someone use the motor on a small skiff to shuttle people back and forth to the bahamas from a boat that was being anchored off shore and after about a month of the motor not being used it now won' tstart and needs to have the carbs cleaned. All the junk in the gas isn't good for the carburetor.

I have a small engine and iusually disconnect the gas line and tie the boat to the ramp then go get the truck drive boat on and just about that time the engine runs out of gas and stalls.
