Does the rudder need to be dropped in order to change the cutlas bearing? Or can the the prop and the cutlas bearing bracket be removed and slide it though the end of the prop shaft and a new bearing replaced? Thank you all Ed

I did it myself
I did exactly the same exercise on an hun 31. Over the weekend, replaced the bearing, and guess what !the shaft did not pass the rudder, Boat on the dry and no crane operators over the weekend. We ended up dropping the rudder and digging 4 ft into the ground. Dropped the rudder into the hole and removed the propshaft, then used a saw to split the old bearing, used a jig from autodiscount to press the new bearing in (20 bucks the jig and $60 for the bearing). Took about 4-5 hours to do the whole job. I got photos if needed. have fun siggi

Dropped the rudder?
Siggi and all, Thank you very much for your prompt responses and please forgive my ignorance. Why is it necessary to pull the prop shaft from the couplings with the transmission? Is it not possible to simply pull the bearing from the shaft while mounted on the boat? The other response to my post indicated that the rudder did not have to be dropped. Are there different shaft/engine mount configurations for the H31? Thank you all Ed

Just did mine last month
Mine is a 37.5 but I pulled the prop, removed the flange from the shaft, pulled the shaft and pushed out the bearing with a piece of pipe. I found that there is an allen screw which holds it in place so it would have been much easier if I had loosened that. I used a piece of 3/8 all thread and some large washers to press in the new one. In retrospect, I think that the old bearing could have been removed without removing the shaft but I have not tried it.

right tools for the job
If you have the right tools which most yard do, the rudder absolutely does not have to be dropped nor does the shaft have to be removed. The yards have a hydraulic tool that will press the bearing out without removing the shaft. Only the propeller needs to be removed. The $30.00 or so it cost to have them do it is well worth the loss of headache of dropping the rudder and removing the shaft. Which is another method of doing it, just the least desireable one.

don't need to drop rudder
the cutlass bearing can be removed with the shaft in place. The yard I was at had a half-round (steel pipe cut in half) that fit over the shaft (1 in diameter). This was used to force the bearing out. New one went in easier. You can pull the shaft w/o dropping the rudder, if you can get the cutlass bearing out, once the shaft is out of the coupler, it should have enough movement side-to-side to slide past the rudder.
