I was anchored in a crowded area on a VERY windy day. When it was time to leave I untied my anchor line from my bow and returned to the helm. I planned on putting the boat in forward and gathering up the line as I advanced. WRONG, the wind blew me over my line and the anchor chain and anchor wrapped around my prop. The shaft of the anchor actually bent around the base of the prop. At that time a fellow boater lent a hand. It took about fifteen minutes to free the anchor from my drive.
Luck would have it I had a two day old prop on that day. Luckily the only damage was a small chip on my drive case and a very small nick on the prop.
