I am only guessing as well, but in the pictures of the engine, on the ledge inside the engine compartment, it appears there is sludge sitting there. If it is, that boat was under water for some time. If a boat sat under water like that, are there any parts that could be reasonably salvaged? I cana't think of any. The interior is 'baked'. New carpet and upholstery... and then the dash and paint will never be the same. Recovering the seats is not cheap, but nothing in comparison to repairing the engine... I can't think of one thing a person could salvage... even the trailer needs a ton of work and will always be a candidate for more rust even if fixed as good as possible. Sad days...
