The top IPB is not the correct one for your motor, but the one Mumbles is showing is. Note part #14 in his IPB, the top IPB doesn’t show it. My ’56 Johnson 5 1/2 would leak gear oil whenever it was laid down. I found that the gasket #13, that goes underneath part #14 had failed, and oil was leaking there. I found this out after replacing the top driveshaft seal, and the lower unit continued to leak gear oil.
HTH.
