      In the top of this pic is my old bearing, notice the recessed holes
      for the set screws. My new bearing doesn’t have those. Should I do
      that, not worry about it… Any ideas?

      The two cutlass bearings I have installed did not have a recess for set screws.
      Furthermore, I remember the fit being so tight I'm not sure I could have located a recess in front of the holes if I wanted to

      The new bearings will not have recesses–rather when you tighten down the set screws you will be forming the recesses yourself in the bearing. This is so one size bearing can be used in many different struts with different set screw placement.

      In the case of the attached photo, I looks as if the previous installer drilled the set-screw holes before inserting the screws. He would have used a bit smaller than the screw hole. I don’t see why he would have done this. You’d risk damaging the threads for no purpose.

      Thanks for the clarification everyone. I’ll be putting the cutless bearing and the propshaft in on my next evening work session. Well be able to float again after that!

      Sorry I was in Mexico the last two weeks and away from all my PC’s

      You need to place the bearing into the strut and take a drill bit just under the size of the screw holes and drill into the bearing (both set of holes) about 1/4 of the thickness of the bronze outer shell.

      Don’t tighten the set screws too tight as you don’t want to deform the bearing. Use Loc-Tight to hold the allen screws place.

      If you have any questions give me a call.

      Funny thing… Nigel Calder’s books:
      Cruising Handbook – uses Cutless Bearing
      BoatOwner’s Mechanical and Electrical Manual – uses cutlass

      The crusing handbook also mentions the set screws should be set into
      dimples, but does explain how the dimples should be created. Thanks Don!
