I can't see something like that lasting more than a few months before corrosion starts. Then you have new holes in your wood.
What is on the door now? Chances are anything not specific for marine won't fit (door thickness, et al) and won't last.
It is always easy to spend other peoples money, but after a couple months search for replacement exterior sliding door hardware to replace 35 year old stuff, which you can't get replacements or parts for, I settled on Izerwaren. Pricey but now I'm done.

Mary at The Brass Works has amazing knowledge. They sell the Izewaren line and others. She probably knows what came on your boat off the top of her head.
