Just to share an attention point when replacing the cutlass bearing.
With our Siler in the shed during the winter season, we discovered that the cutlass bearing was damaged and actually the propeller shaft got stuck.
This after just one season in use after the upgrade of our propulsion with an AutoProp propeller - which is a serious and good improvement.
After removing the damaged cutlass bearing the cause of the failure was well visible.
(sequence: 1-remove propeller and rope-cutter, 2-push the old cutlass bearing out with a special made bush to forward, 3- pulled the propeller shaft - it just passes the rudder so the rudder has not to be removed).
In our propeller strut there are 4pcs of securing screws to keep the cutlass bearing in place.
The outer shell of the cutlass bearing is however quite thin, and what happened is that, considering to have them "handtight",  the securing screws deformed the cutlass bearing, resulting to locally less to almost no clearance between the rubber and the shaft.
Also the installation of a scissor-part of the rope-cutter to the strut showed a similar impact.

When fitting the new cutlass bearing we gave better attention to the tightness of the securing screws.
With a swing and the propeller is making more than a full turn, alignment and clearance should be OK.
(time will learn!)
