I put a new pump in my old motor, that I am not using anymore, I want to take it out and put it in my new motor, I think their the same, old is 1980 115 Johnson new is 1984 115hp Johnson, I put in a OEM pump kit, housing and everything. One thing I was concerned about was that the new housing vs the old one, the old one had a seal in the top of it that sealed around the drive shaft I guess?? And the new housing didn't?? is this okay? It worked fine for the 1 hour run time it had. Hopefully the gasket comes out okay.
