Either get a survey done profesionally, or at the minimum get a moisture meter and go over the hull with a FINE TOOTH COMB as the saying goes. Being it's an 81 that has had a major redo, it will only be as good as whoever did the work. If it was done right, then it should be a good hull, but if stress cracks are appearing, the owner may know the restoration wasn't done right, and he is trying to unload it before it gets to the point the problems are obvious. EVERY old ROBALO I have seen has had water intrusion problems, and rotted wood. So the deal maker or breaker is was it restored properly or not? As to the engine, they are pretty good, but hang onto your but when it does need repairs. I've got a friends 05 225 here(no VVT), and some basic maintenance on it is going to cost him well over $500 for just the engine. Also make sure it has had the zincs kept up with as some of the bigger V6's had corrosion issues.

The best money you can spend on it BEFORE buying is a survey to make sure the resto was done right IMHO.
