Gearcase interchangeability

[Maxwell-8]

I have a 1969 Johnson V4 no trim and hydro electric shift.
And a 1982 Evinrude v4 90hp with a bad engine. (broken cylinderring and took out the piston and bore.)
Could I make the 115hp engine block work on the gearcase of the Evinrude?

Or could I switch over the trim to the 115hp.

The crankshaft spline is different.----Exhaust housing gasket is different.------So in short , there is no way that your idea will work.

I was already afraid of that. trim brackets are not interchangeable either?
