I have an Evinrude 1976 100hp with a good crank shaft, I'm working on an Evinrude 1983 90hp with bad Crank shaft, is there any way I can swap the crank shaft? Will the 1976 100hp Crank shaft fit a 1983 90hp?
They look very similar but I'm just not sure if they can be swap.
Again I will really appreciated any help

Thank you

There was no 76 100 hp but assuming the crank is from a 1976 V4 the center main is smaller than the 83. If the centers main journals are the same then yes, it will work. There may be some other differences but look at the center mains first.

Very different cranks. You'll need a crank from a 1979 & newer V4 crossflow.
