Discover the secret that commercial fishermen all know about preventing line and weed tangles on their props and shafts. The Shaft Shark has been installed successfully on hundreds of trawlers, ski boats, commercial working boats, power cruisers and sailboats. The U.S. Coast Guard installs serrated-edge weed and line cutters on their boat’s prop shafts so they will never be disabled with a fouled prop. A simple, serrated, circular blade that is made in two pieces that fit easily around any size prop shaft without removing the propeller, the stainless steel Shaft Shark can be installed in minutes and will save you thousands of dollars in repair bills. The Shaft Shark is simple, durable and effective. For more details visit us at www.AB-Marine.com or call 800-801-8922.
