I would like to replace the c board pivot pin . Monty17 It will not budge Any ideas? Also ,what size and type of bolt was stock? Thanks Jon Montgomery 17 Ol'44
My Monty 17 had a ss 1/2 inch bolt. Get a drift pin (long flat end punch) and start by tapping on it with a hammer. This is after you carefully clean out both sides of the pivot pin pockets to be sure which end is the one to tap on. Mine had a nut and bolt head on them, respectively. Check to see what was used on your hull. Be sure to support the board before driving the pin out and, actually wedge it up to take the weight off the pin. It would be a good idea too to remove the stop bolt at the aft lower end of the board which is 3/8th inch in diameter before removing the pivot bolt. When replacing that lower stop pin, while doing so slip a piece of nylon reinforced fuel line hose with a 3/8 inch diameter hole in it to act as a bumper in the future. Having that rubber hose on that stop bolt works wonders when cushioning the contact between center board and stop bolt! As long as the board is out, it would be a good time to check the lanyard knot connecting the board raising line to the centerboard.

Carlos, I removed the old pin completely so I could inspect the bore for the pin as it passed through the cb trunk. I found gaps or holes in the walls of the drilled hole. Those led into the cb innards where the steel punchings live in older Monties. I then plugged one end with a wood dowel and and used a second dowel to plug the other end of the hole. This second plug had a hole drilled into it along the bore line such that when I inserted my caulking tube into the hole I could use the caulking gun to force rubberized caulking into the cb pivot hole and fill all the imperfections in the sides of the pivot hole walls. This effectively filled the voids that had been allowing water to seep into the cb well walls. Thickened epoxy may also be used here instead of caulking. It is a matter then of finding an empty caulking tube which can be loaded with your thickened epoxy. Once whatever you injected into the pivot hole has cured you can remove the plugs and carefully drill out the bore to remove the extra filler. Now your pivot hole bore is truly watertight along its entire length. Then, lube and insert your new pivot bolt. On Fri, Sep 18, 2020 at 1:33 PM carlos navarro <chisailor1@gmail.com> wrote:

Why are you replacing the pin, Jon? Problems? As I recall, your boat Ol'44 had the centerboard and keel completely reworked when Sean had the boat, not that many years ago. On Fri, Sep 18, 2020 at 10:54 AM Thomas Buzzi <thomaspbuzzi@gmail.com> wrote:

Larry is correct. 44 has a new bottom, lead ballast and a new pin. The board was already epoxied by Sean. Bob Sent from my iPad
