[C38] rudder stock/post seal leaking issues

[Max soto]

A while ago I took Estancia out of the water, and removed the rudder. I did read about the Mylar film, bust still have no idea what that is, or where to find it here, so I sanded the inside of the fiberglass tube and applies three layers of epoxy. Tried to install the rudder, but the three layers were just to much, so sanded again a little bit, and right up it went.  No play since 2010!

It was a big job as I had to dig a hole for the rudder while it was on the hard and work the shims in as I moved the rudder post up and down to get them in and seated.  It worked well and I have much less slop (it is not like having a bearing which is what should have been done, but I couldn't figure out how to install a bearing given the space and tube integrity with the hull.  I still have a leak as my stern stoops under acceleration and when on a tack...

>> Yeah you’ll need 3/8” packing for the rudder, and still it won’t be a warranty for no leaking. On Estancia, it just leaks less. There are no bearings on these boats. Is a simple fiberglass tube glassed to the hull.

>>> In order to address leaking you want to make sure that the stuffing box (bronze) is properly glassed into the hull. It most likely is, if not that’s something to address asap. You also want to open it up and replace the flax packing. I believe Edson recommends 3/8”. It’s a tricky job especially if you have the rudder quadrant / radial drive in the way but it can be done. Make sure you don’t strip the bolts and don’t lose them in the cavity by below the stuffing box (the mini skeg our boats have). You may have to do the packing two or three times to get it right but it’s worth it.
