Once I had possession of the boat, I gave the rudder and prop a close inspection. The rudder seemed to have a lot of side to side slop/play, at the bottom tip it seemed to be about an inch (if memory serves me correct). As the boat was on the hard and I didn’t do a sea trial I figured that this play would be, at the very least a clonking noise on the hook. Seeing as I was in for a pound with the hull I figured I’d tackle thisĀ  job.

I looked into replacing the big white lower busing, but it isn’t available from Hunter, but I did stumble upon a solution used by others as outlined in the West System Epoxy manual. It involves drilling holes in the bushing and injecting epoxy with colloidal silica (for bulk/viscosity) and graphite powder (for lubrication). It seemed a reasonable method so I forged ahead.

Dropping the rudder required digging a hole in the yard, there seemed to be several holes that spring! There is definitely a benefit to being on gravel instead of pavement! Funny thing is the hole filled up with water in heavy rains and I ended bailing the hole out to reinstall the rudder.

DSC00071The technique calls for waxing the steel bushing, drill holes, reinstall the rudder and then inject epoxy with 50/50 mixture of silica and graphite. In my case I drilled three holes on each side and three on the front. As you can see from the photo the epoxy merged into one big pad. I like this technique as it creates a zero tolerance fitting that would be difficult to achieve otherwise and I suspect is better then when it left the factory.

It stood a season and seems fine – there is a posting out there with
