at the very least, I would lock tight the set screws. Maybe use nail polish so they'll break loose easier later when you do need them to...? Danny

I also have zincs on the shaft in front of the strut, I guess it eases the feeling of losing the shaft, provided the zinc stays put?

It hasn't been an issue and as a backup I have a zinc anode on the shaft about 3/8" from the packing nut just in case it lets loose. I'm sure the keyway is wearing out as a result but I haven't noticed any increase in play. It's just on my mind as one of those " not quite right" things Brent 27-5 Lake Winnipeg Sent from my iPhone On Jun 5, 2015, at 1:16 PM, Brad Crawford via CnC-List <cnc-list@cnc-list.com> wrote: I recently had my transmission out for a rebuild and upon putting it back in and the boat back together discovered that the propeller shaft coupling is a little loose on the shaft, maybe 1/8” of rotational movement on the shaft, like possibly the keyway is worn?. Have tried tightening the set screws, which secures the coupling but eventually they work loose and again there is movement of the coupling on the shaft. It’s been recommended that I have the boat hauled, the coupling removed, the shaft pulled out and provided the shaft is ok, a new coupling fitted and faced to the shaft, and then reinstalled for a final alignment. My question to the group is has anyone else been running around with a loose coupling and is this something I should be immediately concerned about?
