I'm not too sure of the Eliminator. I simply do not know the line well enough to comment. As for the engine drive package, they are Merc SSM #4's. Most have a Borge Warner transmission, and the drives are a surface piercing type.(the prop actually comes out of the water at the top of it's rotation). They are very strong and expensive. If the trannies gimbles, and drives are in good shape, they are worth more than 8k alone. What is the overall condition of the boat? It may be a good winter project.
I would call Eliminator directly for info. Also try offshoreonly.com, someone there may know more about it.
