It is time for me to replace the cutlass bearing in the shaft support. This morning I went and removed all the bottom paint from the support looking for the elusive set screw that holds the bearing in place. There was none.
I can get the bearing out by making two cuts with a sawzall and tapping out the pieces, but. My question is, does the bearing slide in from the inside end of the support and is held by a snug fit or am I missing something.
Any experience that you can foward is appreciated.

I replaced my cutless bearing last spring, so my memory of the job is fairly fresh.
My p-bracket (what you call the shaft support) has two allen screws in line with the shaft on its port side. Once those were out, I was able to cut the bearing shell in two places and pound the cutless bearing with a hammer and screwdriver until it fell out. This is apparently the approved way of doing this. Once you have done this, you will doubtless locate the set screws.
The sawzall sounds a bit brutal, because the p-bracket isn't very thick, so you don't want to cut any farther than necessary (I sort of overdid it the first time I did the job, but that boat is now someone else's problem). I cut my cutless bearing with a fine hacksaw, inspecting the cut every few strokes.
Putting a new bearing in is fairly easy. You need either a bearing insertion tool, or a piece of threaded rod with two locked nuts and a thick washer on one end. Chamfer the end of the bearing you want to insert in the bracket, then pass your threaded rod through the bearing and p-bracket. Put a washer and nut on the end. Position the bearing at the end of the p-bracket and tighten the nut to squeeze the cutless bearing into the bracket.
As you have already taken the paint off your p-bracket, it probably wouldn't hurt to heat it up a bit - brass and bronze expand tremendously, which would ease insertion.

David, Thank you for your quick reply. I have all the paint off the bracket, but there are no set screws visable. I will follow your suggestion and use a fine hacksaw blade.... I am sure that once I have the old bearing our I will find the set screws, or I will make a new threaded hole etc.....

I changed the cutlass bearing last year on my 1975 Mk III (#466) and there were no setscrews. I cut the old bearing out as described and then gently heated the bracket and cooled the new bearing in ice water. It slid in easily by hand and expanded to fit tightly. I did not add any setscrew, and I have not had any issue with it moving.
Good Luck!
