Don't do it very often!  Running lean raises temps inside, and can quickly turn your motor into a fancy boat anchor.  If it was a quick stumble and die, you should be OK.

Also hard on the entire fuel system, electric fuel pump, injectors etc, etc. They need fuel to keep cool and lubricated!

Not only is running out of gas hard on the fuel system and combustion chamber temperatures, but it is hard to restart the engine after adding more gasoline as the VST, pump, and injectors have to be purged of air before the motor will run correctly. That means multiple starts and stalls, wearing down the battery and having the injectors and electric fuel pump running dry.

They do not like to run dry. Takes a dozen or so attempts to get fuel into system.
Question:
With new tank and pumped up bulb, will engine prime itself with ignition on and allowed to sit for a minute or two?

Generally this situation is not a real problem. It could be a serious problem in bad weather or the wrong time and place.

Is there a quicker way to start after running dry.

Thanks for bringing up this issue.

Lyle,

Click the "Latest Topics" tab and review a couple of recent posts - Fuel starvation, Draining Fuel Tanks, etc.  You'll need to be checking 'everything' from the pickup tube all the way to the motor, as it does sound like some sort of fuel starvation.  Lift pump vacuum and 'clear hose' tests, etc. may help, too.  How's your 'maintenance' - Fuel and VST filters checked/replaced, cleaned?

Phil

The only way to be sure is "testing".  I'm doubting that it's the lines and bulb "directly causing the problem", but could be, if they are deteriorating, etc.  Could be the Lift Pump in that motor?

Unless the well is deep, I'd test first.  Get the Service Manual for your motor(s) - call Barnacle Bill's, the sponsor of this site, with Model and Serial Numbers in hand.  That will at least get you started on how to diagnose problems.

I ran out of fuel in snotty 4-6' seas about 50 miles out.  Couldn't get it restarted.  It turned very dangerous quickly.  Had to limp back on one motor and took about 12 hours.  Killed one battery in the process.  It was so loud in the sloppy seas I couldn't really even hear what the motor was doing.  Still had about 25 gallons left in the saddle tanks but in those seas trolling and rolling that's not a good combination.  Primed the system when I got home and it started up.

If you run out of fuel on a V4 or V6 E-TEC outboard, squeeze the primer ball until hard and turn the key to ON for about 10 seconds. Repeat about 4 or 5 times. It helps if someone can squeeze the primer ball while the electric fuel pump is running for those 10 seconds each time.

That circulates the new fuel through the VST and injectors while purging air out of the lines.  Your motor may run rough for a few moments when it starts but should smooth out normally as the air is expelled from the system.

On an inline engine, the pump does not activate when you turn the key to ON or if you have a manual start.  Squeeze the primer ball as described above and crank the motor over for about 5 seconds or so each time to help purge the air out.
