Need help with johnson/evinrude parts swap

[Texas Skeeter]

I'm no mechanic by no means. Parts changer only and new to changing parts on outboard motors. I have a 1977 70 horse Johnson outboard and it locked up the other day on the maiden voyage/my birthday. So here's my question for the experts. I found a 1975 75 horse outboard that is in good shape with good compression. I need to know if the hole engine with fit on my motor I have now. The 70 horse 1977. And will all the parts on my 70 fit on the 1975 75 horse Evinrude? Steering cables and wiring harness from the motor to my shifter/keyed controller. I had my carbs rebuilt new power packs stator rectifier and everything. And the 75 horse needs a complete tune up.
Thanks in advance!!!!

Will my other parts work on the 75 horse off of the 70 horse johnson to evinrude? Power packs carbs starter wiring harness steering cables and throttle control box-where you start it from and shift it from forward to reverse? Sorry I'm new to the boat motor repair world. Just really needing to know for sure before I spend the motor to buy the parts motor. I just had all of the listed parts above and more replaced and or rebuilt. Thanks Skeeter

Any help please!!!
I have to let the owner of the 75 horse know today if I want it?
But I need to know for sure that all of the above will work and bolt up correctly.
Thanks in advance. The parts changer!!!!

Not all parts would be same, if using a 75 hp engine then all parts that came with that engine.
