What precipitates out of seawater in the engine is mostly calcium carbonate ("lime"). Salt is very easy to dissolve, so that isn't the biggest part of the blockage.

Any decent acid will react with the calcium carbonate. I tested some that I scraped out of a project motor and found that Vinegar also does the job, just takes longer than the concentrated acid.

The phosphoric acid is used in rust converters to convert rust to a layer of iron phosphate.
