When I installed a lift motor mount in my M15 I was faced with the same problem. How can I add backing plates to spread the load? My answer; after a lot of head scratching and contemplation, was to buy a rectangular plastic hatch, with gasket and latch, and install it between the aft end of the sail locker lid and the end of the cockpit coaming I cut the opening for the lid, mounted it per specs; and then it was easy to reach the inside transom wall to add the backing plats; hold a wrench; etc. In the end, it was a big improvement to the boat. I now had an easily reachable small sail locker where I stowed my pail and cleaning materials. Connie ex M15 #400 LEPPO On 8/6/2018 11:25 PM, Lawrence Winiarski via montgomery_boats wrote:
I had a couple of pieces of stainless bent for this purpose for the outside and inside of the transom. It's a job to get in there, but I could (barely) get the nuts on by reaching through the lockers...

Just got a transom ladder for my M-15. Obviously the transom needs some help to support the weight on the ladder without it ripping the transom off the boat. So how is this done. It seems impossible to get inside the transom from inside the boat to add some sort of weight distribution plate on the inside. And what about the outside. Does anyone add a weight distributing piece of wood, brass, bronze, metal, carbon fiber on the outside to support the ladder weight when used? Just wondering how to proceed.
