corrosion under chain plates

Hi. Have mid 70s 14 turbo retrofit (inherited); noticed a bit of corrosion peaking out where stainless chain plate attaches to alloy side rail. Not sure if its really going to break next time but . . . any ideas on a fix without forking out dough (much as I love the boat) for new side rails? Is there a way to reinforce the area? does swapping or reversing the side rail (i.e. put the weak point aft and refasten the chain plates on fresh alloy) help -- and any hints about getting the frame off the pylons (sealed on with corrosion) if I do that? Alternatively, how much does it (a) help fix the problem; (b) effect performance if I just move the chain plate aft a couple of inches (i.e. not having to get around frame-corroded-onto-pylons prob)?

Any other ideas or opinion on those options above welcome.

PS New to this site, but I been really enjoying the info on it...sure to be back

You can reinforce it like shown in another article (I think you responded in that one, too): http://www.hobiecat.com/community/viewtopic.php?t=4056


However, I wouldn't go turning them around because you would have even more holes in the sidebars. I have a bunch of them for sale if you need one.

I rarely have seen one that does not have corrosion at the chainplate. Hobie 16 siderails are the same extrusion as the 14s, but are about a foot longer. I rebuilt my 14 siderail by cutting a 16 down and riveting the chainplates on. That way, I had a fresh bar with no corrosion. Don't forget to put some tape between the chainplate and sidebar to prevent the interaction of the stainless and aluminum.
