Here is a new old-stock metal transom mounting plate 323539 for various sizes of OMC outboards. Check dimensions as shown, this part just might be adaptable to other brands as well. It has a small recessed edge that provides security from losing a motor overboard! (I've seen that happen). Minor shelf wear, but nice uninstalled condition. Ask questions if needed please. Sold to the U.S. and Canada etc. and mailed out within one business day of payment. Thanks...
