I'm chaning the oil in our 21EC for the 1st time since we took delivery in April 2008. Didn't use the boat all that much last season. I'm using a simple brass utility pump (JABSCO) to draw off the engine oil and when I insert the smaller diameter plastic tube down into the dipstick hole and begin pumping it seems that the pump is unable to suck out any oil. It's as if the end of the tube has bottomed out and something is preventing oil from entering the end of the tube. However I noticed that when I slowly pulled the pumpout tubing up and out, at some point (3 inches up or so?) oil then begins to pump and emerge. When all was said and done it seems like I managed to draw out about a little more than a quart. (thought there would be more.)
When I reinserted the dipstick it showed just a tiny drop of oil at the very end of the dipstick, just beyond that lower level indicator "hole" on the dipstick itself. So I figured I was done with removal of the old oil. I then replaced the oil filter, and added about 1.5 qts and subsequently the dipstick indicated full. However what bothers me is that the color of the oil on the dipstick still looked rather dark and not that "clear" brown that I would have expected from clean replacement oil.
So, my question is: Did I remove ENOUGH oil? If not, then HOW can I get ALL the oil out? Should I be using a different pump? Do I have a mixture of half dirty old oil and half clean replacement oil in the engine now? This was a simple procedure on our old sailboat which had a similar 2 cylinder Yanmar. And why am I experiencing what sure seems to be a problem when trying to draw out the oil when I insert the pump tube ALL the way down the dipstick tube? Is it hitting something? Is it creating some inherent vacuum down there that is preventing the removal of the oil? Something just doesn't seem right here. I figured I would post this question. Can someone comment from experience regarding this maintenance task on that engine?
Thanks.
