LU compatibility question

[Kohrah]

I'm rebuilding my 1962 75 hp johnson engine which is an electric shift model. I'm currently looking at a parts motor which is a 1961 75 hp manual shift model.

my question is the lower gear case interchangeable? as mine has damage on the nose of the lower gear case.

It would be easier to put your powerhead on the manual shift model, mostly because when you change over the lower unit, you'll have to install a shifter set up on it too. By doing so, you need to pull the powerhead anyway.

Ok if I were to get the manual shift motor running what would I need to change over for controls? Throttle and shifting? Or could I reuse the electric models shifter?

Another thought/question if I were to swap all the components fro. The electric lower gear housing to the manual housing could that be done?

I know I know 0230 I should be asleep lol

Re: LU compatibility question

I believe the electric shift lower unit is set up differently. You will need to change your controls and stuff, because the controls for your electric shift model doesn't have a shift cable, since it's done through the wiring harness. It may be more cost effective, to sell your manual shift motor and buy a new lower unit housing. At least then, you can have a rebuilt lower unit with new seals and not have to worry about it for many more years.
