What is well known are filters.
No need for water in various forms to pass through the injection circuit to see damage to the injectors.
You still have nothing to show degraded !?
AMHA, the only thing that could work, and already works via additives, is the integration of the condensed water molecules from the reservoir. However, the greater the proportion of water, the more it is necessary to increase the amount of additive and more particularly of the essential lubricating elements. More action = more additive = more cost and pollution.
Do you sell additives or lubricants?
To say that some have done 30 or 40000 km is not valid because the various corrosions do not yet have time to appear.
Corrosion conditions on boats are much more severe than in cars. (Sea air, permanent spray, confined atmosphere, etc.). Considering the price of the boat, he spends little time sleeping at the dock .... the immobilizations and repairs are of an "astronomical" cost and therefore the specifications are very strict on this side and the time between the revisions "optimized".
Yet ...... yet they inject water into the engine. What a bunch of unconscious, injecting water into an engine worth several million euros without knowing that it will not hold, that it will be necessary to change the injectors and the valves and all the shaking well before ..... ..

Since then, apart from very targeted industrial applications, the file has hardly advanced. Manufacturers always stumble on the problems mentioned above and speak in terms of a negative overall balance sheet.
The problems mentioned above are part of the legends, with the means at their disposal, they are still able to do better than amateurs ...
I have long approached the world of automotive equipment manufacturers and the answer has always been the same: we do not know how to do it reliably.
It is rather, we have not studied anything for, but since it is not seller and economical for them, we say "we do not know how to do in a reliable way".
It would be interesting for an engineer who worked directly on the engines of a large automobile manufacturer to come and detail the state of the art of the studies carried out and the problems encountered.
Preferably in retirement, that he has nothing to sell ....
The more advanced the engine, the lower the lubrication provided by the fuel. This point must be taken into account.
Your latest generation car injector is more fragile with or without water.
