Re: Polish props

every time I hit the silt on the side of the ever changing ICW channels here I polish the props.

Re: Polish props

Just simply for the sake of over thinking things....wouldn't polishing a prop possibly create more prop slip? :noidea::noidea::noidea:

Re: Polish props

The cleaner the better. But if you have an ol' slug like mine, it dosen't much matter. She is in the water, I only clean her once a month.

Now!....If I had an ol' red and white Donzi Sweet 16 sittin' in the drive.....heck ye I would polish it....probably everytime I walked past her.

Sno-Bol toilet cleaner cleans up the stainless ones pretty good!

Google "Reynolds number" and "boundary layer". That'll keep you busy for a while overthinking this. Happy reading. ;)

You're technically correct, but in a pleasure boat the difference will be in tenths of a %. It matters on a race boat (or a billion dollar naval vessel), not so much for the rest of us.

If you really want to show love to your props, keep 'em clean, inspect after every outing and occasionally go over the leading edge with some 400 grit wet or dry to smooth out the nicks. That's where cracks start.
