i believe the driveshaft will work but not the shift rod (in 1979 OMC moved the shift connector behind the water inlet screens on the lower unit). The shift linkages are completely different.

Now, you will also need a long shaft exhaust housing, as there are no extension kits. And if you just bolt up the exhaust housing and l/u from a 1984, you won't need to worry about the shift rod nor linkage.

my only advice on the shift rod is to find an older extension connector. it looks like the brass shift rod connector but is about 6 inches long. you see them on ebay from time to time
