Mounted on a Tohatsu 9.9 it worked great as advertised. Be careful when drilling holes as if they are off because the drill bit walked it does take some fiddling to get the bolt thru the hole. Mounting is straight forward Im running a slightly larger prop and I did have to trim some of the plastic. It looked like it would work with a factory prop though. It was very windy and really cant compare to base line top speed. BBBUUUTTTT I can say it will come out of the hole sooner conspired with out it used a timer to check it.
