Sail drives, how bad?

[Whosails]

We have a Wauquiez Gladiateur with saildrive. Installed in 2009. The yard it had been in before we bought it did something wrong and while the former owner was using it, it developed a serious problem. When we looked at it there were chewed up bolts in the locker. We insisted that it be fixed before we bought it. Moral of the story is that I would recommend using a qualified Volvo mechanic on these engines.

Also, it is recommended to use non copper bottom Paine on hulls that have these engines.
