have a 1978 70 hp Evinrude with a cracked head. I recently bought a 1987-89 70 hp VRO Johnson that was being used as parts motor. It's missing one coil and a power pack. Can I take the coil assembly and power pack off of my older Evinrude and put it on my newer Johnson and it actually run.

You want to revive a " parts motor " ?-------What inspection have you done on the 56 cube model?

It's got good compression I believe I can get it running. If I had the money I would just go buy the right parts and be done with it. But as it is I do the river logging out of our local rivers around here. So I can't get no money til I get my motor back going. The main issue is the power that's missing off of the newer Johnson is nothing like what's on my older Evinrude. Im just wondering if if I can figure out where the right wires go can I use the older pack and it work on the newer Johnson

You have to wonder about a " parts motor " that might be a reliable runner.----What other inspection was done ?----Gear oil checked ?----What are your " good " compression numbers on this machine ?-----Use wiring diagrams to figure out how to swap the CD / powerpack.
