Hi Nate,
You can get the seals from a Yanmar dealer. Even though I am not in the
region serviced by Torresen Marine, I use their online parts catalog for the
2QM15 as a great reference. Below is the link to the Yanmar 2QM15 listings.
See the section under "Gear Housing".
www.marinedieseldirect.com/catalogs/catalog.php?owner=mdd&manufacturer=Yanmar&model=2QM15&catalog=Y00R0918
Also, I don't recall which list I read this, but I have read a brilliant
account of someone using a deflated/inflated basket ball as an air lift jack.
You can drive over a basket ball with a truck without rupturing it, so I'm sure
it could withstand the total engine weight easily. This seems like a much
better choice over a scissor jack, and if you don't have one, you can buy one
at Walmart for about $8. While your at Walmart, make the job even easier by
getting one of the cigarette lighter powered tire inflators for another $10.
As a final remark, you can lift the rear of the engine using the rear engine
lift ring and a block and tackle attached to either your boom or interior
mast(just use a good round hitch to keep from sliding).
