My only thought is like others, make certain that there is no chlorine. Obviously, there shouldn’t be if all you do is make RO water. Do you ever put water in the tank from the marina? We often have both RO and shore water, tough to tell how much chlorine, although you can buy test strips. I will sometimes flush with a couple of gallons of RO water drawn from the control panel tap, rather than flush with water from the tank.
Assuming the above is useless advice, you might try looking at https://www.genesysro.com/uploads/docs/STUDY%20OF%20THE-PHYSICAL-AND-CHEMICAL-DAMAGE-ON-REVERSE-OSMOSIS-MEMBRANES-DETECTED-BY-AUTOPSIES-NURIA.pdf
This details some of what can go wrong, including post-mortem pictures. Interestingly, there are several causes for physical damage to the membranes (as opposed to chemical) that might have some bearing on your issue.
