I appreciate the answers, but none of them are actually an answer to my question. I am sure all of you would keep the 575's, but he doesnt want to keep them. Although he loves the boat, thus the basis for my question.

And the answer is, around 10k each.

A friend of mine just bought on at 18k. It had a super chiller but other wise it was stock.

I agree with the $20k for set and another $10k for enhancements, etc and its going to be a rocking,dependable set of 1400 hp for $30k. Good resale too.

Thanks for the input everyone

Who is looking for a new boat John????
