Short sweet n to the point. I just shoveled out the remains of my old transom that somehow held a 250lb Johnson on. Wondering if anyone on here would be able to recommend type of wood (1 3/8” 2x6ft) for my transom that is cased by aluminum skin. Read about coosa, exterior grade ply(wouldn’t this corrode alum?), untreated, starboard. At this point, thinking of using pressure treated, 4layers of oil based epoxy, some sort of thin rubber mat or something on each side and flood 3M5200 on the edges to avoid direct contact. Kinda wingin it. Thanks for any feedback guys!
