Well this is my first post.

So I have a 28 feet sailboat equipped with a 2gm20f and long story short I had the valve underneath the fuel tank that I shut off last fall (which I had closed to tighten some fitting that was leaking)
So I ran with the engine to get off the trailer and sail around a bit and surprise surprise the engine stopped. I anchored to save myself from a certain grounding and got towed back...

So now that I have bleed the lines and managed to start it again with great pain.

I wonder if that did any damage, it wasn’t like running out of gas as there was no air to replace the fuel in the lines. But I guess they must have got squeezed tight and created some pressure in the lines.

So I have two questions: First of, what I explained above, could that do any damage or is there anything special to do.

Also, I haven't gone for another ride but I managed to start the engine again afterward and while in neutral I noticed that when I try to bring up the rpm at 2-3000 and keep it there a few seconds, the engine brings it back down automatically, is this normal, is the engine protecting itself because there is no load or something like that? I vaguely remember noticing that in neutral a couple of years ago but I am not sure of anything now!

Any explanations would be much appreciated.

Thanks,

Welcome aboard MT,
First answer: it shouldn't cause any damage and the only special thing to do is to remember "not to do it again"

Second answer: the engine should run up maximum revs while in neutral and stay there for as long as you have the throttle open. Why it isn't doing that is something that I will have to leave to wiser heads to answer.
