The OMC saildrive units were very popular with boats that size for a comparatively brief period. These units were moderately reliable if carefully maintained. The lower units have held up pretty well in fresh water but have not done all that well in salt. Basic maintenance parts are still available since many of the parts were common to outboards with larger production runs. From what I gather from discussions with OMC saildrive owners, many of the more unique parts are pretty much unavailable. For example, I followed the process that a fellow went though when his outdrive lower unit was damaged and they were unable to find a replacement lower unit. In his case they ended up glassing over the hole in the bottom of the boat, beefing up his transom, installing an outboard motor bracket and buying a new 4 stroke outboard. He never found that arrangement satisfactory and so sold the boat a few years later.
If I remember the model numbers correctly the earlier C&C 27''s were all pretty much an evolution of the original C&C 27 but the Mk V was a totally new boat. If I am correct that the Mk V was the new design, I like that model of the C&C 27 better than the earlier boats. I thought they were a very well rounded design, offering good performance, construction quality and reasonable accomodations. I have sailed on a 27 equipped with a
wheel steering and thought that killed the boat a little by taking up a lot of cockpit space and also damaging the tiller steered boats delightful light and balanced helm. I would look for a tiller version of this model.
You sometimes see earlier models listed as a Mk V so I am not 100% certain that the model that I am describing is in fact the Mk V. The model that I am describing was distinctive from earlier models for its outboard rudder. Due to ease of maintenance over the life of the boat, I personally prefer the outboard rudder on the Mk V to the inboard rudders on the earlier models. That said, outboard rudders are more vulnerable in a docking situation.
The earlier C&C 27''s seem to have a strong following and were very good boats for their day. There seems to be some ambivilence about the Mk V amoungst owners of these earlier boats so I will leave the discussion of the Mk V vs earlier C&C 27''s to the folks who have those particular preferences.
