Re: Different Props that fit on an 57' Evinrude Fleetwin 7.5
The 7.5 Evinrude was only in production 4 years.
That prop very likely is simply a polished bronze prop
of unknown age.It is possible that the 5.5 and 7.5 share gear cases.
While the pitch may be different physically the props may interchange.
All props can be reconditioned if they are in reasonable condition.
With the long shaft conversion I wonder if the prop may be specific to a special application
a 3 blade is somewhat unusual on the 7.5.
