Cowl years that would fit a 1966 18HP Evinrude Fastwin 18602C

[brianweber4]

Howdy! I have a 1966 18HP Evinrude model 18602C. As you can see it already has a 25HP Johnson cowl that was painted by duck hunters! What year cowls would fit? Would a clamshell cowl from say a 1950's 18HP Evinrude fit? Lookin forward to your reply.

You would need a cylinder head , lower cowling and other brackets to make that 50's cowling fit.
