At the risk of starting a war there seems to be a strong opinion that stern drives are doomed to fail and cost the owner a fortune.. I accept that shaft drives appear more "robust" for the perspective that they are pretty much entirely internal and for the most part based on ancient and well proven technology.. Looking at the schematics of my Volvo SX drive there really doesn't seem to be that much to it that can go that badly wrong..
Is it just the older ones (20+ years old) that are problematic with newer drives (say 10-15 years old and newer) being more reliable?
Is it purely a corrosion issue because they are in the water that causes problems with stern drives?
Is there an inherent design issue?
Is it simply a lack of maintenance that has given them the "unreliable" reputation?
Its certainly hard to deny the advantages of stern drives, that being apparently significantly better performance and fuel efficiency than shafts..
