I have a 1957 18 hp Johnson FD-11 that my son and I are starting to work on. I believe the pinion gear has some wear and wanted to replace it. He's my problem. The parts manual only gives you a part number of 377147. That's for the whole assembly. I was hoping to get the individual part numbers of everything in the assembly. Any help would be appreciated.

If the pinion gear shows obvious wear, you can bet the other gears are worn also. And bearings/bushings. Do some better diagnosing before spending $$$.

After doing some more investigating, the gears look just fine.
