Hi Paul and group,

The bearing spread does look marginal for an aircraft Don.
As much as 600 ft pounds due to prop gyro torque can be applied
to the output flange of an aircraft PSRU.

A boat PSRU never sees anything like that much torque.

What is the distance between those output shaft bearings?
