Fountain problem areas?
 

I am going to look at a 1993 27' fountain fever and was wondering if there are any specific areas that are prone to issues with a fountain. I am fairly experienced with mechianics, but am concerned with any constuction issues, areas prone to moiture, etc. Thanks in advance.

Only problem I had was some water getting past the deck/hull joint in big water....removed the rub rail and siliconed the seam and screw holes.
