Hi,
I have a 1984 MKV.
I have experience working on cars and automobile engines.
How do you change the oil on the single Yanmar?
How on earth do you get an oil pan full of oil out from under the engine?

Buy pump to remove the oil, available at any marine store. They come with skinny little tubes for sucking oil. Then suck the oil out through the tube for the dip stick. My pump is a Pela 2000 and it works great. Or spend a bit more and get an electric pump.

I have a Pela oil pump (one of the ball-shaped ones that Jim describes) and I find it utterly useless on my Yanmar. I've had better luck by borrowing one of the big Pelas. But again, the thin-tube-down-the-dipstick doesn't work - what does is cobbling up a mess of different hoses so I can clamp the intake hose to the top of the dipstick tube. This doesn't reach the very bottom of the sump, but I'm assured this removes enough oil that an effective change is made.

also, run the engine for 20 minutes to make the oil nice and warm - it will not flow at all when cold

For years I have been draining the oil from my 1gm10 by removing the plug at the bottom front of the engine oil pan - can't miss it on my engine. [BUT BE VERY CAREFUL - there is a screen and a spring that come out - be sure to put them back in the same way.] That removes almost all of the oil. I then use a pump with about a one foot suction hose to get the rest from the back of the oil pan as the engine slants down at the rear. It's very easy, and works very well.

Thank you for the replies.
What brand oil do you recommend for the change?

I suspect that we all have our biases, but I suspect all brands are very similar, if not the same given there are many more brands than refineries! I have been a life long Esso fan, and have always had good luck with it. But I think you can't go wrong with any quality name brand oil.

Brand is to a large extent irrelevant - they're all going to be good enough for a season's operation (and after a season, the oil should be replaced without fail). The main criterion is that the oil be rated for diesel service, which is class CD. Our club mechanics recommend 15W-40, which is suitable for outside temperatures up to 40C and down to -15C. In NS waters you could probably run with 10W-30, but 15W-40 gives you a bit more margin and the cost difference wouldn't be worth considering against the value of the engine.
