We finally got it done! We are the proud new owners of a 1974 55' Kingscraft Houseboat. We are the 3rd owners, the second owner had it for 25 years and the first owner custon ordered it from the factory. It has 2 factory installed marine air units, central vacuum, and a flybridge. She's powered by twin Chrysler 318's through Paragon V-drives into bronze screws. The owner had a current survey (April 2012) and we did a 3 hour sea trial Sunday. Monday the marina hauled her out and power washed the bottom. The hull has a Devoe paint and anti-fouling finish. I am very pleased with the hull condition, a few very small areas with mild pitting, but overall excellent condition. The anodes (magnesium) are in good shape and will easily last another year or two. The downsides are that the genny (Kohler) is a little tired (uses a fair amount of gas and I believe needs at least a carb rebuild), the windows are stock (the plastic tracks need a LOT of cleaning and work) and starboard throttle cable is stiff. The engines start right up when cold & idle smoothly. The boat ran and steered very well, the genny didn't flicker for over three straight hours and the sea trial had zero issues.
It came with tons of documentation (brochures, blueprints, original pricing sheets, and more) and papers for all of the systems. As I get the opportunity (and figure out how to do it) I will post scans of the documents and pics of the boat.
I didn't even know they offered factory marine air, the roof is smooth and didn't have to have roof AC holes filled in. The neat thing about this we have the 1973 Basic price list with option pricing. Turns out the 55' came standard with 2 custom heating/cooling units ($1325/unit option on all other models)
We are planning on storing it on the hard (right terminology?) for the winter and do a few interior changes.
We are happy with this boat, I hope we feel that way a year from now (I don't think my smile will fade by then)
