I would go to marineengine.com and look up both engine models, to make sure the cranks both have the same part number. That's the best way to make sure.

Actually, the two crankshafts do have different part numbers but that may only be due to a difference in the driveshaft size/splines......

It would be easier just to source another lower unit imo.

Sorry but will not fit due to driveshaft splines as posted earlier and only works with the 25 hp motors....

The OP wants to put a '78 crankshaft in an '82 powerhead so he can use the '78 lower unit.....it would be way easier just to source another lower unit but any chance this would work?
