Are you sure you are removing all the old oil during the change?

Why specifically Yanmar owners? I resemble that remark! The 2 quart spec in the manual is for a 7 degree installation. My boat is a Yankee and the Yanmar replaced a A4. The engine is mid ships and the prop exits about 5 feet behind the engine, literally out of the keel. It looks like the motor might be mounted steeper than 7 degrees. I wonder if that accounts for the different dipstick. My high low marks are about 3 inches apart. The example in the manual shows the marks much closer. Hard to believe some dipstick actually replaced the dipstick with the wrong dipstick, but then.....

Yes. Besides, if i wasn't, it would make the level read high, not low, right?

You've got the wrong dipstick.

The high/low marks should be about 3/4" apart, or thereabouts -- no more than 1".

Somebody else in your marina must have a 2GM. Borrow their dipstick and re-calibrate yours.

Yep

Sorry I read the post wrong.

Is there a part number on the blade of the dipstick so that you can check it is the correct one?

Got an answer!

Emailed a Yanmar service/training center in NJ w/ pictures of the motor installation and the dipstick. Here is their response:
"It is our recommendation that you fill the crankcase oil to the "Full"
mark on the dipstick. This will give you correct lubrication under all
conditions and engine angles."
This makes sense to me so I'm going with it. The range of opinions I received was amazing, including one from Yanmar that made no sense at all. BTW, the dipsticks on Yanmar 2GM's differ. I have a dock mate who has the same motor and dipstick I do (2 1/2" between high and low marks). His motor is mounted with a mere 3 degree angle, compared to mine at 10 degrees. So not all are 3/4" apart.

That is interesting.

Would you care to share the advice you received from Yanmar?

Also, according to my Service Manual, the 2 qt oil capacity for the 2GM is for an engine installed with an angle between 8 and 15 degrees.

It makes sense that there could be more than one dipstick for the same engine, depending on installation angle. But I would have thought that any variation in dipstick was to allow for a correct reading of the oil level based on installation angle, rather than for a different quantity of oil.

Another possibility is that you have a larger/deeper oil pan that allows for a greater lubricating oil reserve. I've never seen that mentioned in my Yanmar documentation, but I know Betamarine has something similar....

When someone in this thread said "why not contact Yanmar?" I felt silly. Why didn't I think of that?! It's funny, but because the boat builder is long out of business, I'm not used to thinking in those terms with regard to the boat!
Anyway, I emailed Yanmar and estimated a 15 degree installation. When I actually measured it later, it turned out to be 10. In an case, Yanmar stated 15 degrees was the absolute maximun installation angle. Ironically, they then stated that if two quarts worked for the previous owners, they would advise me to do the same. Not very scientific! I expected them to say something like; "a 15 degree installation requires __ liters of oil. As I stated in an earlier post, my manual specifies a little over two quarts for a 7 degree installation. But yes, Yanmar must use different oil pans which is fine with me. A larger oil reservoir is better as far as I'm concerned. It's just strange it's not reflected in my manual which looks original. According to the surveyor that referred me to the place in NJ, they have probably seen every type of Yanmar installation ever done. They apparently didn't think the dipstick was unusual. Just goes to show - can't believe everything you read!
