pirate gearbox jams on yanmar 3GMD

Morse selector wont go into neutral... I did some testing and found...
Cables clear. Selector clear. Gearbox arm free to move but not able to go into neutral.. ....Prop shaft jammed.!
I used force on the prop and the shaft freed..The Problem is in the gearbox.
What would cause a gearbox selector to jam?
Any ideas please?..

Re: gearbox jams on yanmar 3GMD

The knowledgeable people will ask what gearbox you have, is it a Kanzaki or a Hurth or a Kanzaki-Hurth. Dose it have clutch cones or clutch discs. Maybe not easy to answer but you may have a bent shifting yoke which is internal and unusual to be abused. Hope one of the CF experts can help.
Wish you any easy fix.
