M17 centerboard, thanks everyone for all the help on the CB. After reading I find I was on the right tract. I made a cardboard pattern using a tick stick, transferred to 1/4" ply, used a marker to find pivot pin point, drilled ply, inverted 1/2" pivot to check swing, went to fabricater and he cut it out of 1/2" plate, drilled both holes, being epoxied as I write, using cutting board plastics for shims. I can feel the movement on the water. Thanks again, Mike.
Great hearing about the progress, Mike. On Thu, May 19, 2016 at 2:44 PM, michael beebe via montgomery_boats < montgomery_boats@mailman.xmission.com> wrote:

Quick progress. What kind of plate- steel? lead? At some point I am going to add cutting board HDPE shims to the centerboard trunk on my M15, mostly because it fits in there extremely loose and makes quite a bit of noise in light winds or at anchor. HDPE can adhere with excellent strength to fiberglass with West G/flex epoxy, and the alcohol wipe + flame treatment protocol (www.westsystem.com/ss/assets/gflex/GluingplasticGflex.pdf). Tyler

Good for you. I recommend that anyone who is buying a Mr. Jerry Montgomery boat just do a simple Check. Take a portable drill motor and a 3 inch hole saw and drill a hole in the keel about 6 inches up from the bottom. Take a look and if you see Mush like this photo pass on it. We've done a lot of repairs and new center boards over the last 18 years and A boat with severe rust isn't worth buying. After drilling out a 3 inch plug its easy To patch with some glass. Takes about 10 minutes. Be well Bob Montgomery boats and NorSea Yachts. 949-489-8227
