I gave them a call and it turns out that they are used and shop overhauled.
Or I would have bought them..

I thought something had to be fishy. A replacement 2GM for my boat is more
than the price you were quoted. Yanmars are great engines but the company
should really be investigated for price fixing since almost every dealer sells
for list and it's tough to get a discount. This on top of the fact the things
are overpriced in the first place. Almost $5k for a 2 cyl diesel. **** you
can buy a built Chevy V8 street rod crate motor for that kind of money.
