I'm doing a paper for products liability......does anyone know if outboard motors on recreational boats usually come equipped with propeller guards to prevent injury?

Thanks for the info Jim. This should help me prove a case----It seems like manufacturers would be smart enough to place propeller guards to avoid liability in case someone ever comes in contact the engine......

yeah,
I used to know someone when I was a kid living in Dallas, who at the lake (Grapevine) got sucked into the prop in a freak accident. Her leg was badly lacerated and much of the meat in her leg was lost. She will have to wear a brace the rest of her life. She can't walk without it. Apparently the boat driver did not know she was in the water, by the motor, she was about to climb in the boat. He thought everyone was in the boat, and put it in drive. She was rushed to the hospital and fortunately did not completely lose her leg.

Wouldn't a propeller guard decrease performance signifcantly?

Matt: I'm clueless when it comes to boats---tell me more---why would it decrease performance? Would a propeller guard weigh all that much? Would it slow the boat down?

Actually I love your argument Matt.....I think you just made the difference between an A and a B for me in this course.....
Ryan,
I'm not a boat nut. (I see where you are going I think).
I am just saying that a propeller needs to be as unencumbered as possible. Guards would restrict the flow of water into and around the propeller, thereby decreasing the effectiveness of the engine, and increasing fuel costs.
Best of luck.

well, have you seen the design of props on research submarines? The housing is sheetmetal that goes around the prop, but does not restrict flow, since it is thin and the water passes over it easily. I was thiking of something like that. Then again, I know shit about fluid dynamics and water propulsion methods.

why not just make like those UK sub's like Trafalgar: a "pump-jet" system ? just an idea........
