PO-15 lower unit question

[David Bartlett]

Hello,

I am building a PO-15 from my parts bin and looking through the parts manual it seems there is a thrust washer between the upper and lower driveshafts. I may have one in my “stuff” but want to know if there is anything special about this washer or if it is just a generic one.
I am currently in the process of sorting and cleaning the best parts, checking bearings, etc.

Thanks for your help!

It is a hardened steel washer that supports the weight and force of the upper driveshaft. Without it, the driveshaft will bottom out on the bushing of the pinion shaft and eat it up.
