Hello old salts on this list
I am presently building a 701 floatplane on Czech amphibious floats.
My friends bought exactly the same plane ready-to-fly from CZAW,
After a year they have already experienced multiple roller bearing
failures of the float main wheels and corrosion of all landing gear axles.
This might have to do with using the plane in brackish water
and as I will need to land in salt water too, I am very interested
to hear about what can be done as prevention.
For example, using other bearings and axles than the stock ones,
using certain protective oils and procedures, perhaps a change to
nylon wheels etc. Any suggestions and experiences are welcome.

I'm not expert at all, but given the extreme lack of participation on this list,
I'll step up to the plate and offer this: On my Aventura, the legs are nickel-coated
to resist corrosion from the salt spray, so -- although I know it's
stating the obvious -- it would seem to be a matter of selecting the correct metals,
e.g., instead of standard bearings, get stainless steel bearings, etc.
My only personal experience has been with nickel-plated steel, and 316 stainless
steel, and both of those hold up very well against salt water corrosion.
