On 
http://optimisticwanderings.tumblr.com/post/34066669524/making-it-happen 
and http://optimisticwanderings.tumblr.com/post/32122840821/hauling-out 
it looks like your prop is further aft than mine.

You can see on 
http://www.alberg30.org/maintenance/MechanicalPropulsion/Zincs/ that my 
prop hub is very close to the cutless bearing housing. On all of the 
rudders on http://www.alberg30.org/maintenance/Steering/RudderVarieties/ 
the prop seems more centered in the aperture.

Was the prop shaft changed when the engine was changed?
