3.5 outboard prop shaft assembly

Postby fast rigger » Wed Mar 11, 2015 8:03 pm

Hello everyone! Can anyone tell me thread size of a 3.5 prop shaft assembly? I have a lower that needs some cleaning up and I can't seem to pinpoint the exact pitch and diameter of the threads. Thanks!

American thread 10-32 on the shaft itself.

The internal thread in the lower unit is a special left had thread. Forget about finding a tap.
