Salt Water Operation

I am about to relocate from downstate Illinois to the west coast of
Florida. I have a Nitro bass boat w/ a 115 hp Merc 4-stroke outboard. Can I
use this rig in sal****er w/o inviting serious damage?

I have seen many Florida boats with outboards badged for "Sal****er". I
assume they have a cooling water system designed to resist sal****er
corrosion. Is there a significant difference between these outboards and
mine?

Any advice and recommendations would be greatly appreciated.

Thanks to all.
