1972 50hp Johnson Electric Shift . Compatible lowers??

[Skyler2]

Hello, I am trying trying to find out if a Johnson 70hp lower might fit my 1972 (50ESL72) 50hp.Johnson electric shift. I'm not sure of the year of the 70hp, but it is an electric shift. I just have an ebay pic.
Any help would be appreciated.
Thanks, Skyler

I don't have info on older motors but newer motors have completely different driveshaft part numbers.
If you think about it you are talking about a 2 cylinder to a 3 cylinder the 70 is almost 50% more powerful.
I'm sure someone will be along with more up to date info.

Thanks Spike. That makes sense to me. I can add that I only need the housing. My skeg is bent and I was hoping to find an undamaged housing. I may try and straighten the skeg, but that is another topic.
Thanks, Skyler

your skeg can be straightened by some one who works with aluminum, if bent badly don't try it yourself. or you can replace it with a skeg guard.

i have a 1972 50 hp eletric shift and a 1974 3 cylinder standard shift . the gasket is differen`t than the 50 . the 74 50 hp i have is different than the 1974 70 hp . the prop is the same . you can replace a 1974 50 hp standard shifi with a 72 eletric shift . you will ned some parts off the power head of the 1974 . like the plate behind the carb where the 2 cables fasten insted of the one cable hookup . also the shifting diode will need to be removed . the part where the shift cable and the throddle cable hooks up . the block is the same . as the 1974.
