    Excellent, Thank you. Can they be changed while the vessel is in the water?

    i wouldn't do it once you remove the rudder arm from the shaft to remove the seal you have to remove a spiral clip that holds the seal in then the seal water will be coming in

    I think that red seal guide is facing the wrong way.
    Also, the post looks like corrosion or barnacle fouling??

    Did somebody push the rudder up?

    You know Capt, I thought of that. I had the boat backed in for the 2000 hour MAN overhaul at a facility with skinny water as you got closer to the bulkhead. I actually tied up about 15-20' off the bulkhead. Another factor - both shaft are leaking. That red, whatever it is, was down on the seal, I pulled it up.

    Also, that's bubbling water at the seal and shaft joint. It's just in poor focus

    That red thingie may be a way to keep junk off of the seam from the inside.
    It is a pressed in seal like the ole Strong seal system. I'm not a big fan.

    Yep, Lets do this job on the hill.
    Please keep us updated. :)
