Doel fin made 2 different designs, first came the one piece design with a clear slot where the lower unit went and it bolted thru the cavitation plate. The second was a 2 piece which fit on both sides of the cavitation plate. Both were shaped like a wing- flat on the bottom and arched across the top.
