Treated wood for aluminum pontoons? Be sure to use quality carpet, glue them down good and staple them. Because if that carpet tears and the board comes into contact with bare aluminum, galvanic corrosion will take place because of the copper used in pressure treated boards. That and sometimes the green can bleed through your carpet and stain the pontoon.
I would stay away from pressure treated wood. Water activates the corrosion, salt increases the rate of corrosion. Use Cedar if you can, or regular wood, yes you will need to replace every few years with regular plywood, but repairing a pontoon where it sits on the bunk seems to be a more troublesome task.
