Quick update

Denise and Barry are right. The rudder has to be dropped. - And the damned thing is HEAVY! I'd estimate 200lbs.

In order to remove it, I had to dig a 2' hole under the rudder, and then pound the retaining bolt out of the quadrant, and then I had to loosen all the bolts that hold both halves of the quadrant together (4 9/16" and 2 7/16"). I then pried both halves apart with screwdrivers. The retaining bolt is a 3/8", 16 thread, stainless steel cap head screw, that is 8" long. I mushroomed the end, and buggered the threads while trying to remove it. New one is on order.

Here are some pix of the old, new, or improved parts.

Old stuffing box and hose

Purdy, isn't it?

Look closely and you will see where the shaft was rubbing on the stuffing box. THIS, I believe, was the source of the noise.

New PSS Shaft seal

1 & 3/4" ID to fit over the shaft log. 1" Shaft.

Rebalanced Prop, and balance report

That's a 16" 9 rev/foot prop with a 1" bore.

Contrary to what I believed above, there is NO bore reducer used in this application. The guy that I dealt with at NE Prop, said that a propeller shaft zinc would take care of any galvanic corrosion. (I don't think so...)

New and machined coupling

Everything - including the new Prop Shaft
  • New Cutlass Bearing
  • New Prop Shaft
  • New PSS Shaft Seal
  • New Coupling
  • Rebalanced Prop
  • Machining...
Almost $1K worth of parts in this picture.
