Where to buy used engines....

[Palmetto]

I have been reading this site for awhile, and I have really enjoyed it. Some of the boats that have been restored are truly works of art. I would love to be able to achieve that someday.

I am looking at 23' that needs new engines, but I can only afford used. Is there a good place to look on the interent for used engines? I have search boattrader, but I have no information on the people I could potentially be buying from.

Thanks for the help,
