I am looking at a 1989 Gibson 36' that from what I can tell is in good condition. I've been on it several times and never noticed any problems. The owners told me that they have taken good care of it and have even had some recent upgrades done to the electrical wiring, prop and engine.
What are some of the most common problems that I should look for when buying a new houseboat?
Do you folks have any advice for a first time buyer?
