Well after getting my prop tangled up in a lobster line for the second time in 3 years (each locking up the prop and requiring a diver), I think I need to install something to prevent this from occurring again. I did see one boat this spring that had a thin skeg bolted to the strut that looked like it may deflect the line away from the prop but not sure where to find that. The other alternative is to install line cutters on the prop shaft. I would be very interested in hearing from people on what works for them. I have a fin keel, spade rudder with a 3-blade prop.
