As far as I know, Suzuki is still one of the worst for corrosion. They use ALOT of zincs in them to help deal with it. For a newer engine like that,vyou do have the advantage of knowing it should still be good, and you could keep on the flushing and protection. Yamaha is still the best from what I've seen. Yes there were some problem childs like the 1st big 4 strokes, but they have gotten those issues worked out(I know of an 05 225 that gets used strictly in salt water, only gets flushed via the flush hose hookup for 2 or 3 minutes, and that engine is great with virtually no corrosion). I don't have much experience with Honda, but I know Spare says they're the worst, and I would be inclined to believe him from the amount of corrosion that was on my 05 75hp that had very little use in salt water. And I would say Evinrude and Merc are top notch as well.

The biggest killer in salt water is lack of preventative maintence. Keep them flushed, change the zincs every couple of years, spray em down with corrosion block every month or so, and most any of them will treat you well.
