Agree. From 1973 to 2017, my shaft drive system has had: Prop swaps for better performance under sail or power, depending on what we were doing. Tighten stuffing box. Zincs Strut tightened and PSS seal put on in 1988. Hit a log and bent the shaft. New shaft, new cutless bearing, and new PSS in 2014. The prop was reconditioned. $1500 yard bill covered by insurance. More zincs. Some zincs.
A sail drive from that long ago would have replaced several times over at the very least. I would estimate the sail drive total maintenance over that time period would have been 10-20 times as much. I would still have the original shaft absent hitting something.

I would never have one. The more changes in direction you have in a mechanical device the more complicated it becomes. In one instance here the yard got a strap around it when taking the boat out of the water. I need not explain the result.

What is the group’s experience with sail drives from any engine builder? Google has revealed Volvo and Yanmar have the bulk of the market and sail drives are becoming the rule vs. the exception on newer boats over the past 10 years or so. While they are reported to be quieter / less vibration than traditional shafts, from what I have read the maintenance beyond changing the oil in the drive unit annually [just as one would for the engine] is not really a DIY project. Replacing the 2 seals, particularly the one keeping the water out of the boat, sounds like they are a yard job – and expensive ones at that; on the order of $2 - $5k depending on the location of the yard. And the “recommended” seal replacement interval is reported at every 5 to 7 years… While many owners may go well beyond that, what happens to an insurance claim if one has exceeded the manufacturer’s “recommended service” interval? Any experience / information with sail drives is appreciated.
