Yes I installed one about 100 feet from the sea with plenty of surf 
and it lasted a few months.  Parts were replaced and it lasted for 
several years running hard in a different location, until it was idle 
for some months due to alternative power from temporary huge diesels 
on site.  When it was turned back on it failed due to the salt 
attracting water to the parts that had not been replaced.  Keeping it 
warm had delayed this failure for years.  Salt attract water but heat 
evaporates it.

I'd seriously consider putting one in a good sized, well sealed room 
close to the sea. Separate diesel and battery compartments.  Access 
via dead lobby space, to minimise air changes to outside salty air in 
stormy weather.
