Dave brings up a good point. I have a line cutter on my prop shaft. I selected the Prop Protector rather than the Spurs. My thinking was that the Spurs model has rotating blades that cut in a scissors fashion. Depending on the size of line to be cut, this chop, chop, chop action could put periodic shock loads on the transmission and running gear. The Prop Protector is a round disk that is razor sharp on the outer circumference that cuts through the line as the line tightens. I don't know if I'm right, but that was my thinking. I don't know if my Prop Protector has ever been put to use. If I did encounter a line, I didn't realize it. I don't have any idea how large a line these shaft line cutters provide protection. But to echo Dave's words, the last place I want to be is under my stern in a seaway with a knife, cutting away the line from a relatively sharp prop and line cutter. Now medical emergency comes into play!

Freeing it of a serious wrap of commercial nets at sea might be more than the crew can manage. Not life threatening but certainly will require outside assistance unless one is a "seal" or similar underwater expert.
