Thanks Howlandwoodworks - funny you say.... there is a piece of aluminum angle stock running across the entire transom (inside, 8" above outdrive) starboard to port. I'm starting to feel good about what I've got going. Btw, nice 12' Sportman, such a cool boat. That must have some...
Thanks MIA, I appreciate your input. Once I have the outdrive removed I can measure the transom aluminum plate (the hull) and add that thickness to the Coosa (1" 3/4") to determine the entire transom thickness (inside surface to outside surface). I think it's safe to assume (that could be...
The instructions (referencing flatness uniformity) and the diagram suggests the specification of 2" to 2.25" total thickness is for a fiberglass boat. My guess (that could be trouble) the aluminum transom plate combined with the 1" 3/4" Coosa would have a comparable strength to a 2" wood and...
Thanks for the reply, yes, I'm laminating the 1" and 3/4" COOSA to get to the same thickness and set-up (a smaller 3/4" square laminated to a large 1" rectangle) as the existing plywood setup equaling 1 3/4". It sounds like you believe that combined thickness/setup of 1 3/4" COOSA is...
Hi, I have a aluminum 1979, AMF Crestline '19 Norseman with MerCruiser 140 with a Mr (pre Alpha 1) drive and need to replace the plywood transom. The existing plywood is 1" spanning the entire transom with a smaller 3/4" piece (total plywood transom thickness 1 3/4"). There is no epoxy or...
