Also a late reply but maybe helpful to new viewers: I have a 1986 ScanMar 33, have owned it and maintained it for 11 years. It is a good boat and you can find reviews and information about it on the web. I have not had any trouble finding parts to maintain it, although most things are metric or European so it is not a simple as an American production boat. Like any 30 year old boat it requires upkeep. A few of the important modifications it required were redesign and replace the chainplates (they are of a poor design and have known to break), rerouted the bilge pump system and added a second pump (it exited through a through hull below the waterline and relied on a back flow preventer) to exit above the waterline to eliminate possible siphoning, removed and rebolted the rudder as it was leaking. I also replaced the prop shaft strut because I ran over some lines and it broke and bent the shaft. At that time I switched the shaft to SAE one inch and put a new a new prop on. My next job will be to drop the keel, inspect and replace the keel bolts.
