Looking for the original portholes, any suggestions would be great. Also, feedback on mounting the outboard, in the well or on the outside?
If you go the record here for this particular boat you will see a number of links that should be the most helpful for this kind of thing. Also, the builder, Mariehom is still in business. That's where I would start. A number of folkboat (INT) links that are also listed.
If you have trouble finding them, let me know.
Here's one link: http://www.solopublications.com/sailmarieif.htm#2marieif
