Default Whats a 502, 415 HP worth?

I've got a 1999 502 415 MPI that I bought 4 years ago which had a reversion problem. I ended up buying another engine and no longer have a need for this.
The engine still has only 90 hours on it, I did not have it rebuilt. What would be a fair price?
Thanks!

Complete engine, MPI (Multiport Injection) The engine has been stored indoors, everything else appears to be in great shape.

Yes it has all wiring and accessories-starter, alternator, MPI unit, etc. Mercury replaced this engine with a brand new engine. I bought this engine from the dealer.

You say that it had a reversion problem. What was/is wrong with it?

The exhaust was leaking water into the engine causing the oil to become "milky". I'm not a mechanic but I understand that the heads would have to be gone over along with the bearings (to make sure they are not rusted).
