Need OMC Crankshaft Journal Specs

[seakaye12]

The motor is a 1959 Evinrude Fastwin

Crankshaft P/N is 0304733 : Replaced by 0315286

In particular I need the size specs for the center main bearing journal.

Thanks !

Don’t have the Evinrude specs handy but the comparable Johnson FD series with that crankshaft shows 0.9995-1.0000 for the center bearing journal.

Yikes that was fast Bob! Thanks!

Yes; the Johnson should use the same crankshaft.

I’m curious…..what Johnson Manual are you using to find that information? I have the 10th Edition and so far specs like that are eluding me…..

Somewhere along the line, I came across some Johnson Condensed Service Data. Here’s a copy – a little hard to read since I had to reduce the file size.
