Coat every stainless steel machine screw with Ultra Tef-Gel at reassembly. This is an anti seize compound and corrosion inhibitor all in one, a very good product for our Marinettes. Don't be cheap, coat every screw generously! You will appreciate it later when you have to remove them and they back right out with no corrosion to boot!

Looking good, but I'd use small nylon flat washers instead of that full pattern piece. The reason is to let water flow below the connection, to reduce crevasse corrosion.

Jeff's suggestion is the one that makes best practice. Using thicker rubber or (better) Starboard as Carl did are OK, but the former is less complicated and certainly separates metal from metal. As I reflect on what I did (now nearly 20 yrs ago, I took the base pieces to a machine shop and had them deepen the original channels under the rail feet to promote better drainage. But the use of cheap washers is the elegant solution. (That's why some call Jeff Capt Elegance)

Happy 4th

The nylon washer worked well for me also. I put a dab of silicone on each washer and positioned over the screw hole and let it dry in place before I started replacing the rails. This was the "Jeff" method and sure beat trying to get a washer between the base and deck with silicone screws in hand. You really can't tell that the washers are in place once I reinstalled the rail.

Good luck

Sorry to disappoint you Gentlemen but I am not going with the nylon washer fix. I am blowing out all of the "Pit Corrosion" with glass bead, etching, priming, filling, priming and then painting these areas before installing my 1/4" white Starboard insulators with all new fine thread ribbed aluminum 10-32 threaded inserts, fine thread 10-32 fasteners and Ultra Tef Gel on the threads. I am also implementing this fix on all of my Aft Deck rail bases, cleats, handrails and everything else that fastens to my Marinette topside this way. Gentlemen, this is preventive maintenance 101, this is a bona fide and sound fix for the problem spots arising out of a poor decision by the factory aboard our beloved Marinettes, this is a sure fire way (albeit an expensive one) to completely isolate the dissimilar metals on our boats so pay attention, watch and learn, more to come and photos will follow...

Here is a photo of one of my six cleats installed using the 1/4" Starboard isolator spacers I had CNC machined to match the footprint of my cleats. I'm using 18-8 stainless steel 1 1/4" long allen flat head machine screws and stainless steel washer faced lock nuts (with ridges). These washer faced lock nuts eliminate the need for a separate lock washer, handy considering the tight hand holes your working through to tighten them down. More to come on this topic...

Good work getting access to the underside of the cleats.
