How often are you clouting the prop?

Not that often thankfully .. but I like to have the blades as near perfect as possible and hate seeing imperfections in them .. it must be the yachtie coming out in me,... where i'll do anything to gain half a knot

That will be cosmetic. It does not affect the stainless in any meaningful way.

It's caused by small pieces of mild steel on the file transferring to the stainless, where it discolors.

As an aside, most files will rust anyway, so you'll have some potential for the same staining, even with a new file.

Agreed. Also, the oxide film that stops stainless from rusting will only form properly on a highly polished surface, so unless you follow up the filing with ever finer grades of emery to polish it, the stainless steel will rust.

Your average wire brush will certainly put too many scratches on the steel for it to remain rust free, especially in a marine environment.

Sorry to hear about your mishap Keith, bring your prop up to me if you want. I can clean up the edge and re-polish the whole thing, still got my mobile?

Kind offer, thanks very much (and yes I still have your number). I've filed the edge smooth without getting too carried away, so will see if it affects performance in any way. Had planned for a spin out tonight, but by the time I got home I had lost all enthusiasm. One hot day and suddenly total lethargy sets in! The garden and the barbecue won me over.

Fantastic vis this afternoon, could just make out the Brittany coastline due south when coming down Les Varines. That must be at least 35 miles.

Yes I've noticed a few good days recently, normally I can see the light at Cap Frehal from my bedroom window but the other night I could also see houses and street lights etc. Last saturday was a public holiday in France, I was watching a firework display near Mont St Michel at the same time as another somewhere near Paimpol!

Would that be the Indian Summer they've forecast for the last few years running?. About bloody time it turned up. 'spose they'll be right eventually if they say it often enough.
