Damned rocks

Managed to miscalculate the tide just a tiny bit last Saturday on my way back from France, and clipped a rock on the entrance to my beach mooring/harbour. Guess if I'd not bought so much wine the boat may have been riding a little higher in the water and all would have been well. Photo shows the passage I have to take (and no, the tide wasn't quite that low when I tried to return )

However, the upshot is, I've burred the edge of one of the baldes (and probably left a groove in the granite). Is this likely to be enough to cause a balance issue or vibration. I'm presuming I should just lightly file the rough edge and go for a spin and see.

Doesn't look bad at all, a quick file would sort any sharp edges out. Use a file thats never been used on mild steel though.

A decent prop shop could dress most of that out.

Just file it.

That's one thing - we may have bigger tides than you but we don't have much rock!!!

Sometimes I'll take the prop off and lightly hammer the edges to restore the leading edges of the cup profile if its had a ding, which one blade looks to have had, before finishing with a file, but as said, it doesnt look too bad

Thanks guys. I'll gently take a file to it. I don't think the blade is twisted or damaged except for the burr on the edge. I was at tickover speed and as soon as it caught, the engine stalled.

The mild steel will end up in the stainless steel and cause it to rust.

Someone I know did it on a stainless mast, used a wire brush to clean the surface up, the mast started to rust and said person denied all knowledge. Had to paint it in the end.

Yep or things that should be on land rather than in the sea!
