Cutlass bearing replacement...

Cutlass, cutless? Whatever...

Step one! Pull rudder (see other thread )

Find the setscrews through the 3" of bottom paint, remove 2.9" of bottom paint helps (why did he paint the strut? Dunno...)


Cut the inside, I used a reciprocating saw CAREFULLY. Better to use a hacksaw if you don't have a recip saw or are ham fisted and like to hack everything. Then peel it inside all the way through, if it's hard, cut it a little more. Then just grab it with vice grips and it comes right out


lightly sand the inside, mine was pretty clean...


Then take a blowtorch and melt all the snow around the boat, better do the whole yard...

coat the bearing and the inside of the strut with dishwashing liquid, assemble the threaded rod (yes, 3/4" rod is overkill, It's what I have, left over from another project) coat the nut and washer with more soap, and tighten carefully making sure it goes in straight


Then cut this part off, I used a oscillating saw (harbor freight $39 special) and clean up the edges

Great job! This is a pretty easy job and I don't know why more people don't attempt it. I've written the procedure a number of times on SailNet and the onlt suggestion that I have is that the bearing goes in real easy if it's frozen overnight.

Get rid of all the bottom paint on the strut....it isn't good for the strut.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

Yes this is an easy job but when you have to remove a rudder not so simple.. doh'

The only thing I'll add is that I use the set screw hols to split the bearing. You don't actually need to cut all the way through and risk scoring the strut, just leave a paper thin piece and snap it with the push bolts..

On thin walled bearings, like sailboats have, this is not an issue but as the bearing walls get thicker it is tougher to peel them so you usually need two cuts which is a PITA.









As eMKay said.. easy..


Oh, and do strip that paint off and check for de-zincification..

does't really matter what you turn with, just as long as you don't turn too hard You can strip that soft bronze very easily

That isn't a bolt, it's a Maine Sail designed cutlass bearing removal tool.

Looks easy enough, but the rudder removal and prop shaft removal (and re-installation) are what scare me.
