On Yamahas, is there a difference b/w Saltwater Series and HPDI engines?

[johnk86]

I'm in the 175hp to 225hp engine range. Looking at the Yamaha page, the "Saltwater Series" is only offered with EFI. But the HPDI Series has a freshwater flush as standard as well as "advance corrosion protection". In two strokes, is there a difference between the two as far as how well they will take saltwater? If it is, then it seems that to get a motor that will "live" in saltwater one is limited to an EFI engine if one is narrowed down to a 2-stroke Yamaha.

Found out the answer to my own question by contacting Yamaha directly. All of their HPDI engines are "Saltwater Series" engines with the additional stainless steel and anodes. At least that's what the guy said.
