Yanmar 3MY30 oil capacity

[kenhoneycutt]

This is dumb question I know, but does anyone know the approximate capacity for a 3MY30. Can't seem to find my maintenance manual and I need to top off the level. I drained 3 liters out this weekend and replaced with a little over 3 for the filter but the dipstick is still showing on the lower dot. I thought the manual said somewhere around 2.8 Liters but maybe I was off by a liter?

Need to find that @#$% manual.

Ken,
Oil capacity is 2.8 L or 3.0 qts. Info can be found on page 25 in Operation Manual. If you have lost yours I belive you can download a copy from the Yanmar site. Wait 10 minutes for the oil to drain back into the pan, and be sure that the dipstick is pushed all the way down before you check the level.

That's right. Same as the earlier 3GM30F.

As for the low reading on the dipstick, is the boat possibly listing to port?

Sounds like maybe I didn't let the oil drain down into the pan long enough.

Is that 2.8L with or without the filter. I can't remember if the filter has an affect on the level?

Out of curiosity, why are there two yellow "Engine Oil" caps?

I watched the video on the Yanmar website on maintenance procedures. They show both yellow caps but they only show oil being added to the top fill. I'm assuming that it is just another fill spout in case you can't access the top filler for some reason? Kind of scared the sh!t out of me when I first saw it and thought maybe I had to add some quantity of oil there for some reason (I hadn't studied the manual all that closely).

Don't remember any mention of the oil filter either on whether that is counted in the 2.8 Liter..I added a little extra after I saw that ~ 3 liters drained out without the filter removed.

I wondered as well that it might be for convenience depending how the motor is mounted. I watched that part of the video several times before adding oil to make sure they were both the same.
