That was by no means, a complete list. Your surveyor should be checking things like bilge pumps, engine WOT rpm range (is in spec); prop pitch and diameter; fuel tank and hises inspection, and lots more. But while he's doing his thing, you can be looking around for things that you might find (like the stereo, etc). WHat size anchor, chain, and rode, and does the windlass work? Cabin windows open and latch closed ok? Any signs of water intrusion in the cabin? Any smells?
I haven't had any issues with my 282, other than the on-board mattery charger has gone bad, and pops the breaker (not GFI). I have a replacement that I will be installing. Do you have access to any service records? I am in the process right now, of replacing both water pumps, and all 4 thermostats, of which 3 were stuck open. The stats cost $50 each, and are a pain in the butt to change. Has this ever been done on the boat you are buying? If not, it may be a point to consider having the dealer do that before taking delivery, if there are no records of that being done.
I read that post about no sealant on the hull-deck joint, by that guy on THT, but don't think it's a widespread issue, or this forum would have lots of posts about it, as this is an all-Grady White forum with a lot of owners.
When is the survey and sea trial? Keep up posted how it goes.
