Mike,

I had the same problem after a new engine install. I had a slight list to
port when sitting at anchor. I ended up making lead ingots by melting old
lead flashing and pipes and pouring it into an old aluminum ice cube tray.
The shape was just right to put into the bilge on the staboard side under
the galley cabinets. I made about ten ingots and painted them with four
coats of paint so I could handle them and not get lead on me.

The only caution is to do the melting outside so you do not fill your house
with lead fumes.

I would be happy to give you any additional info.
