    thread locker for below waterline- SS to bronze

    I am about to reinstall my rudder that I have rebuilt.

    The rudder has a cast bronze shoe that fits to the bottom of the skeg with 2 5/16 flat head stainless steel bolts. The bolt heads fit into a recess in the shoe, pass thru the skeg (about 2 inches) then thread into the other side of the shoe.

    This is the only support for the rudder. It worked for the past 40 years, 20 in my experience. When I disassembled it a few months ago the bolts came right out with a good crank on a screwdriver.

    The shoe fits close to the skeg but I wont put adhesive because disassembly would be very difficult.

    I am not too worried about the bolts loosening, but some thread locker would be nice to use.

    guys, what do you think? What would you use?

    Should be a picture attached.

    Btw, the shoe is the lower pintle, with a nub that mates with the lower end of the rudder post.
    The shoe has been cleaned up and a new bearing was made.

    If it's any help, I believe that a couple of the prop and shaft zinc manufacturers use Vibra-Tite and others just specify 'Loctite'.

      Thanks Van.

      Guess the others are out sailing.

      Think I will use blue locktite.
