Starboard not so good....
Starboard is great for little projects, but I don't think it is designed for structural, i.e., weight/load-bearing, projects. Dave has the right of it; a new bracket from Hunter is a lot cheaper than losing your outboard if/when the starboard fails.If you're determined to build your own wooden bracket, use marine plywood, or build it up from hardwood laminations. Oak, and some other species, have oils that interfere with glue bonding; use an acetate-soaked rag to wipe the oil off the bonding surface.The ONLY glue you should use with woodplywood is epoxy. Epoxy penetrates the wood pores, to make a very strong bond. 3M's 5200 is not a glue; it is typically used in the hull/deck joint because it is flexible (can remain watertight), and can be removed.Pick up a few books about boat building/repairing. Wear protective gear when working with epoxy, and only work in a well-ventilated area. The human body will develop a severe sensitivity/allergic reaction to epoxy over time. Once it develops, it remains with you for the rest of your life.
