I have sterndrives on the Windy and i'd never dream of having them again on any boat, unless I was dry stacking it, and even then I wouldn't be keen
At least with the higher fuel consumption of shafts, you spend the money when you use the boat, so the value and the cost are more related. Sterndrives cost even when you can't use the boat due to weather, circumstances etc, and they're also much more likely to ruin a holiday, with all the associated hassle, disappointment and costs.
Another way of looking at it is that Sterndrives are more about fixed costs per season, so the incentive is to use them as often as possible to reduce the cost per hour.
Shaftdrives, my wallet would wince every mile I cover.
