No oil in drain tube

[jsta281]

So Saturday I thought I would drain the oil. I have never serviced it before as I just bought it last October. Admittedly I did not warm up the motor as recommended. With that said nothing came out of the drain hose as in not a drop. The inside if the hose and brass fitting at the end did not look like oil had ever touched or passed through it. Checked the crank case and it was right up to level with very clean oil.

I am pretty certain that the motor got serviced spring last year and then never ran as it was at the dealer on the floor for sale. My question is why did no oil drip out even slowly when I unscrewed the brass fitting?

did you take the fill on the valve cover cap off?

When I brought my pre-owned 206 home from the dealer, it was about 1 quart over full or even a little more. I didn't worry about damage because we only test drove the boat about 15 minutes or so (due to the old "low on fuel trick") and I know the dealer hadn't run it because they just changed the oil.

Back to the point, I tried to drain some of the new oil out cold and it forever to drain. The stream was as thin as dental floss.

No but having changed the oil in my cars and trucks I have never had to to get the oil out. I always eventually open it but it never appeared to be any significant instruction.

It seems there is some kind of brass manifold that the drain tube is Attached to that is then attached the oil pan. It must be a ridiculous small port for the oil to drain out.

When it is warm how long to drain that seems like a really long time?

Its warm after your regular trip. Even one or two sets won't get the oil to its hottest temp. These engines run cool.

Even hot, it takes hours to fully (mostly) drain the oil. Many of us let it drain overnight. Some (and now me) attach the suck up to the hose connection and help it along. If you do that version, its best to let the engine rest an hour so for most of the oil to drain to the pan. Some would argue (and its a good argument) it can take a day or more for all the oil to report back to the pan and that is somewhat true but it is diminishing returns. Also the remote filter hose can trap some oil. If you don't get most of the old oil out, your new oil change will look dirty fast. You may also overfill. If you drain out 3.5 and put it 5, you will be over full.

There are many threads on this.

My remote drain is useless without attaching a suck pump to it. I could leave mine of for days and wouldnt drain on its own either.

Cold oil flows really slow. The oil drain hose is usually clipped or secured above the oil level in the crankcase, but there is some oil in the hose, that does not get warm, unless you run the engine for a long time.

When I change my oil, I usually take a suction pump, and some empty oil containers to the boat ramp, and just after putting the boat on the trailer, suck out about 3 1/2 quarts of oil. Then the boat is taken home, and the oil drain hose is threaded out the bottom of the boat, and put into an empty container, and left overnight. I commonly get 1/2 to 3/4 of an additional quart of oil out. And by waiting overnight, a lot less oil comes out of the oil galleys on the engine when the filter is changed. (Ford GT-40 engine)

Sorry double post.

After reading on here I did expect for it to come out really slow but boy I had no idea. I have a suction pump I guess that's what I'll try.

I had a similar issue, I realized there was still quite a bit of drain hose in the boat, the hose curled up to the oil pan. When I pulled the entire hose through the hull it began to drain better, still slow but better. Oil like water will seek its own level so pull all the hose through.

I might have mentioned I would let it drain over night or days (boat offsite). I usually drain it into the last 5 qt bottle I used for my truck and then put back the same amount I drained out. I know after an hour or so it might drain only 2 quarts or so. Like DC said, it can take hours for all the oil to return and then drain out the small i.d. hose.

Thanks I can see why being warm is a must. I think I will do as someone suggested and after I take it out this year drain it at the marina when hot. Then tow it home and let it finish while still warm and leave over night.

It's super slow when cold, but still very slow when warm. I used to leave mine overnight even when warm. To avoid frustration, I'd recommend getting something like this:

then get a fitting for the pump that matches to the one on the boat drain hose. When you get home from using your boat, hook up the pump while everything is still warm.

What about the oil that was in the filter? Do you funnel that into the 5qt bottle too?

To the OP, I've had very good luck changing the oil on vacation while still on the water. After a hard run, I hook up a pella suction pump to the drain hose and pump it up to get suction. It's usually slurping air by the time I've got the oil filter off.

I'm a desk jocky hack, and even I can get the oil changed in under half an hour this way.
