info needed on ocean winds 33 ..

Things to examine closely:
Engine and saildrive condition. I have done a full rebuild of the MD7A engines in situ. They run like new now, but not a fun task. Saildrives are susceptible to galvanic corrosion; inspect closely.
Electrical. These are old boats, no telling what you might find. While re-wiring after a lightning strike, I found a lot of “improvements” by previous owners that were downright dangerous.
Steering. If not cleaned and lubed at least every couple of years, the Whitlock gear boxes WILL lock up.
Rudders. Water intrusion from the thru bolts at the gudgeon and pintle connection will lead to swelling and eventually, cracks at the seams.
Winches. If they are the original Gibb units, spares cannot be had new. You're stuck looking for used units on auction sites.

These are the only major boat specific items I can think of right now. All in all, a pretty short list for a 30+ year old boat.
