I have to put in a new prop shaft and had to droop the rudder
I notice the upper part has grease on it but the lower part of the rudder shaft is dry
should the Whole thing be greased and what kind of grease to use?

The strut has no set screws what if any thing goes on the outside of the cutlass bearing?
boat yard guy sad nothing or they glue them in with epoxy.
same question about the prop and the shaft , and the coupler?
propspeed on the section of shaft in the cutlass bearing?

project started out as repack the stuffing box and touch up the bottom paint, and 
apply some prop speed to the shaft and prop.
cutlass bearing is gone so shaft has to come out, so the rudder has to come off.
prop shaft hits dead center on the rudder , not a snowball's chance of getting one back in with the 
rudder in place.

boat is a 85 MK1 with the original engine and transmission. And the answer to the question of
how long is the shaft ? 56.75 inches with a 2.5" 1/4"X1/4" keyway on the coupler end
