what thickness of shim to use?

[newfhonda]

Hi Boats.net,

I would like to know what thickness of shim to use in a lower unit on the prop shaft for a F60TLRF, Serial# 6C5L1018122. Or is this something that you wouldn't know until you put the unit together again?

Thanks!

Need to get a service manual and follow shimming procedures in manual.
