Vent Symptoms ... could be "SHT"

[dbuffington]

Hi Folks!

Oh, I'm afraid to ask, but...

What happens when you run an outboard connected to an external tank with the vent on the tank _closed_?

It's a conventional (i.e., non-pressure) tank, and the fuel pump is mechanical (not electric).

Be gentle. Your answer will determine whether this thread, my day and myself should be moved to the "Stupid Human Tricks" forum

Thanks!
Dave

Usually the motor stops running after a short bit.

And if the tank is plastic, it starts to cave in from pulling a vacuum. BUT, if your really dumb, like me, you CAN continue squeezing the crap out of the bulb and getting it to run for 20-30 seconds at a time while you slowly go crazy trying to figure out WTH is wrong with your motor!!

And after sitting there trying to figure out why it stopped you can sometimes restart it and it stalls again in 2 minutes.

Drove all the way to the lake while trailering the boat only to realize I don't have keys to the boat Club.

The:

It's no big deal that my bilge pump doesn't work, my boat doesn't leak and MAN that's a lot of rain and we're filling up fast! Club.

and of course, the infamous:

Of course I put the plug in, what do you think I am, STUPID? Club.

Of course, I'm not a member of any of those....

So go post it on the SHT forum.

You probably did no damage to the engine, and minimal if any to the gas tank.

good luck

ah, but I had my daughter's boyfriend out to teach him the basics of boating. My ego will take some time to recover :redface:

If yer ego is that sensitive, you better go find something safe to do, like watch movies.

My son did that once. Somehow the engine was still running even though the the 12 gal plastic tank was sucked down to about a six!
