Can't see how it wouldn't hurt performance. Edited by Tom W Clark on 01/14/10 - 12:30 PM Kevin 1988 11' Super Sport, 1987 Johnson 15hp.

Quite a bit safer for anything that strikes you at very low speed from the side. An example of such a strike would be... uhm...uhhhh... Well, I can't think of any apart from what was demonstrated. Someone help me out with another example. Edited by Tig on 01/14/10 - 6:06 PM 1995 Dauntless 15, Honda 50

You can tap your cleats with a bat and it's not going to hurt; take a full swing, and it will. The video shows a propeller spinning out of the water at idle speeds. Big deal. A boat cruising at a typical 4000 RPM with a motor that has a 2:1 gear ratio will have it propeller spinning 2000 RPM. The blade tip of a 14" diameter prop will be traveling about 84 MPH. I don't care if the leading edge is rounded or not, it is going to hurt.

If a careless operator starts the engine and puts it in gear while people were still climbing into the boat via a stern ladder, I can see the potential for this to be less painful if it came in contact with someone than if they were hit by a regular propeller. However at higher RPMs as mentioned above, the Safety Propeller going to cause some damage. Cliff 1966 13' Sport with a 1993 40hp Yamaha 2 Smoker
