I have to replace a cracked lower chainplate on my 1995 36MK11. Any experienced information, step by step approach would be appreciated. I have replacement plate coming from Catalina Direct. Also was courious on recommended caulking. I hear 2 different opinions, silicone vs higher strengths like 4000, 4200 or 5200.
Any experience appreciated.

Lower chainplate replacement
John, When you get the chainplate removed allow the hole, time to dry. You may want to use a hair dryer to assist in this process. Always use Butyl Cauking. This cauking does not harden and remains pliable. 5200 is an adhesive, and I do not recommend using in this application.

I think cracking a chainplate is very hard to do. Wonder how it happened. I've had everything else that can go wrong on a boat go wrong but not that. Butyl tape is the way to go imho. Easy to work with, easy to not make a mess, effective and it lasts.

John, I have those chainplates if you need them.
Don't use 5200, clear marine silcone works fine, just keep an eye on them and re-caulk before a drip can cause damage.

I would recommend either Butyl Tape or Boat Life polysulfide calking over silicone. Both will adhere better and remain tacky. Silicone tends to shrink as it cures and pulls away from surfaces.
