Looking for advice on buying a P337

[aldoradave]

It seems that Aviation consumer perpetuates the story line that the 337s are maintenance hogs. Indeed there are a few idiosyncratic items that do require different levels than a conventional twin but I don't think those to be of much importance when evaluating the relative maintenance needs.

From my experience of owning a Seneca III (same motors as my P337) I don't think there is much difference at all. My guess is that some compare the 337's maintenance costs to that of a single, and of course it is going to be more--but not in comparison to other light twins.
