I am in the process of restoring a 1986 Glassport 220 Walkaround. Unfortunately Glassport is no longer in business. It has an OM inboard outboard sterndrive engine. The doghouse that was on it is basically crumbling away. I was hoping to purchase one but it doesn't seem that is likely. Anyone have a template or anything to go by since it looks like this is going to be a do it yourselfer kinda thing.
