Stupid Mistake Channging Oil in Yanmar 2GM

I was going through the fall winterizing ritual yesterday when I ran into a problem while changing the oil in my 2GM.
I use a Jabsco siphon system where you insert a small tube into the oil pan via the dispstick 'tube'. When doing this I had a hard time getting the siphon started and pushed the tube farther into the tube.
I got a good part of the oil out but when I went to pull the tube out I couldn't. it's stuck! On what I'm not sure. Of course I had to resist my first instinct to yank it out.
My best sesnse tells me I need to pull the oil pan off, I have no deisre to do this given the fact that the engine is in the boat.
I've looked at a schematic and can't find what it could be stuck on other than the oil intake.
Knowing that there are few firsts, I'm wondering if anyone has done the same bonehead move or could give me an idea of what the tube could be stuck on.
Thanks

Sorry have not done that but if you have decent access disconnecting the engine and sliding into the cabin on a 2 by 4 frame is a lot easier than you might think so if all else fails.....

Good Luck

Also no idea what could be binding the tube, but did you try twisting it as you tried to pull it out? Could be that it's catching on the bottom edge of the dipstick tube, and rotating it may finesse it out.

Doons, Before pulling the pan try everything you can think of, twist, jiggle,
push more in and pull until it breaks, at this point you have nothing to lose.
If the whole thing comes out intact, you win. If part of it is still in the
engine, not so good.

Good luck, Dabnis

Fill with hot oil

Can you soften the tube by refilling the engine with hot oil

See if you can detach the dipstick tube. It might press fit or be held on by a machine screw. Then you'll have more hose to work on.

How about opening the compression valves, and turning the engine?........i2f

20 MPH ain't fast unless, you do it in a 1000sq 3/2 house on 10foot waves

I think I would try running a piece of stiff wire down inside the tube that is stuck and use it to try and push the tube out of/away from whatever is holding it. You might also try compressed air down it to blow it out of where ever it's stuck. Good luck.

I would be curious to know which advise was taken and how it turned out.

What about refilling the engine with oil and starting it. As others have said getting the tube hot should help more than anything else, but with the engine running, you will also have vibration and a bit of pressure helping.
Block the tube end and the dipstick hole with a rag to stop oil going everywhere.
Wait till its hot and use some mole grips to twist the tube as it is removed.
Good luck.
